pub fn id(&self) -> &'static str
pub fn is_format(&self, data: &[u8]) -> bool
pub fn from_stream<'a>( &self, stream: &'a mut impl Read, ) -> Result<Codec<'a>, SkCodec_Result>
§impl Handle<SkBitmap>
impl Handle<SkBitmap>
pub fn new() -> Handle<SkBitmap>
pub fn new() -> Handle<SkBitmap>
Creates an empty Bitmap without pixels, with ColorType::Unknown, AlphaType::Unknown,
and with a width and height of zero. PixelRef origin is set to (0, 0).
Use Self::set_info() to associate ColorType, AlphaType, width, and height after
Bitmap has been created.
pub fn info(&self) -> &Handle<SkImageInfo>
pub fn info(&self) -> &Handle<SkImageInfo>
Returns width, height, AlphaType, ColorType, and ColorSpace.
pub fn width(&self) -> i32
pub fn width(&self) -> i32
Returns pixel count in each row. Should be equal or less than row_bytes() /
info().bytes_per_pixel().
May be less than pixel_ref().width(). Will not exceed pixel_ref().width() less
pixel_ref_origin().x.
pub fn height(&self) -> i32
pub fn height(&self) -> i32
Returns pixel row count.
Maybe be less than pixel_ref().height(). Will not exceed pixel_ref().height() less
pixel_ref_origin().y.
pub fn color_type(&self) -> ColorType
pub fn alpha_type(&self) -> SkAlphaType
pub fn color_space(&self) -> Option<RCHandle<SkColorSpace>>
pub fn color_space(&self) -> Option<RCHandle<SkColorSpace>>
Returns ColorSpace, the range of colors, associated with ImageInfo. The returned
ColorSpace is immutable.
pub fn bytes_per_pixel(&self) -> usize
pub fn bytes_per_pixel(&self) -> usize
Returns number of bytes per pixel required by ColorType.
Returns zero if color_type() is ColorType::Unknown.
pub fn row_bytes_as_pixels(&self) -> usize
pub fn row_bytes_as_pixels(&self) -> usize
Returns number of pixels that fit on row. Should be greater than or equal to width().
pub fn shift_per_pixel(&self) -> usize
pub fn shift_per_pixel(&self) -> usize
Returns bit shift converting row bytes to row pixels.
Returns zero for ColorType::Unknown.
pub fn draws_nothing(&self) -> bool
pub fn draws_nothing(&self) -> bool
pub fn row_bytes(&self) -> usize
pub fn row_bytes(&self) -> usize
Returns row bytes, the interval from one pixel row to the next. Row bytes is at least as
large as: width() * info().bytes_per_pixel().
Returns zero if color_type() is ColorType::Unknown, or if row bytes supplied to
set_info() is not large enough to hold a row of pixels.
pub fn set_alpha_type(&mut self, alpha_type: SkAlphaType) -> bool
pub fn set_alpha_type(&mut self, alpha_type: SkAlphaType) -> bool
Sets AlphaType, if alpha_type is compatible with ColorType. Returns true unless
alpha_type is AlphaType::Unknown and current AlphaType is not AlphaType::Unknown.
Returns true if ColorType is ColorType::Unknown. alpha_type is ignored, and
AlphaType remains AlphaType::Unknown.
Returns true if ColorType is ColorType::RGB565 or ColorType::Gray8.
alpha_type is ignored, and AlphaType remains AlphaType::Opaque.
If ColorType is ColorType::ARGB4444, ColorType::RGBA8888,
ColorType::BGRA8888, or ColorType::RGBAF16: returns true unless alpha_type is
AlphaType::Unknown and AlphaType is not AlphaType::Unknown. If AlphaType is
AlphaType::Unknown, alpha_type is ignored.
If ColorType is ColorType::Alpha8, returns true unless alpha_type is
AlphaType::Unknown and AlphaType is not AlphaType::Unknown. If AlphaType is
kUnknown_SkAlphaType, alpha_type is ignored. If alpha_type is AlphaType::Unpremul,
it is treated as AlphaType::Premul.
This changes AlphaType in PixelRef; all bitmaps sharing PixelRef are affected.
pub fn set_color_space(
&mut self,
color_space: impl Into<Option<RCHandle<SkColorSpace>>>,
)
pub fn set_color_space( &mut self, color_space: impl Into<Option<RCHandle<SkColorSpace>>>, )
Sets the ColorSpace associated with this Bitmap.
The raw pixel data is not altered by this call; no conversion is performed.
This changes ColorSpace in PixelRef; all bitmaps sharing PixelRef
are affected.
pub fn pixels(&mut self) -> *mut c_void
pub fn pixels(&mut self) -> *mut c_void
Returns pixel address, the base address corresponding to the pixel origin.
pub fn compute_byte_size(&self) -> usize
pub fn compute_byte_size(&self) -> usize
Returns minimum memory required for pixel storage.
Does not include unused memory on last row when row_bytes_as_pixels() exceeds width().
Returns usize::MAX if result does not fit in usize.
Returns zero if height() or width() is 0.
Returns height() times row_bytes() if color_type() is ColorType::Unknown.
pub fn is_immutable(&self) -> bool
pub fn is_immutable(&self) -> bool
Returns true if pixels can not change.
Most immutable Bitmap checks trigger an assert only on debug builds.
pub fn set_immutable(&mut self)
pub fn set_immutable(&mut self)
pub fn reset(&mut self)
pub fn reset(&mut self)
Resets to its initial state; all fields are set to zero, as if Bitmap had
been initialized by Bitmap::new().
Sets width, height, row bytes to zero; pixel address to None; ColorType to
ColorType::Unknown; and AlphaType to AlphaType::Unknown.
If PixelRef is allocated, its reference count is decreased by one, releasing its memory
if Bitmap is the sole owner.
pub fn compute_is_opaque(bm: &Handle<SkBitmap>) -> bool
pub fn compute_is_opaque(bm: &Handle<SkBitmap>) -> bool
Returns true if all pixels are opaque. ColorType determines how pixels are encoded, and
whether pixel describes alpha. Returns true for ColorType without alpha in each pixel;
for other ColorType, returns true if all pixels have alpha values equivalent to 1.0 or
greater.
Returns false for ColorType::Unknown.
pub fn dimensions(&self) -> ISize
pub fn dimensions(&self) -> ISize
Returns ISize { width(), height() }.
pub fn get_subset(&self) -> IRect
pub fn get_subset(&self) -> IRect
Returns the bounds of this bitmap, offset by its PixelRef origin.
pub fn set_info(
&mut self,
image_info: &Handle<SkImageInfo>,
row_bytes: impl Into<Option<usize>>,
) -> bool
pub fn set_info( &mut self, image_info: &Handle<SkImageInfo>, row_bytes: impl Into<Option<usize>>, ) -> bool
Sets width, height, AlphaType, ColorType, ColorSpace, and optional row_bytes.
Frees pixels, and returns true if successful.
row_bytes must equal or exceed image_info.min_row_bytes(). If image_info.color_space()
is ColorType::Unknown, row_bytes is ignored and treated as zero; for all other
ColorSpace values, row_bytes of zero is treated as image_info.min_row_bytes().
Calls reset() and returns false if:
- rowBytes exceeds 31 bits
image_info.width()is negativeimage_info.height()is negativerow_bytesis positive and less thanimage_info.width()timesimage_info.bytes_per_pixel()
pub fn try_alloc_pixels_flags(
&mut self,
image_info: &Handle<SkImageInfo>,
) -> bool
pub fn try_alloc_pixels_flags( &mut self, image_info: &Handle<SkImageInfo>, ) -> bool
Sets ImageInfo to info following the rules in set_info() and allocates pixel memory.
Memory is zeroed.
Returns false and calls reset() if ImageInfo could not be set, or memory could not
be allocated, or memory could not optionally be zeroed.
On most platforms, allocating pixel memory may succeed even though there is not sufficient
memory to hold pixels; allocation does not take place until the pixels are written to. The
actual behavior depends on the platform implementation of calloc().
pub fn alloc_pixels_flags(&mut self, image_info: &Handle<SkImageInfo>)
pub fn alloc_pixels_flags(&mut self, image_info: &Handle<SkImageInfo>)
Sets ImageInfo to info following the rules in set_info() and allocates pixel memory.

pub fn try_alloc_pixels_info( &mut self, image_info: &Handle<SkImageInfo>, row_bytes: impl Into<Option<usize>>, ) -> bool
Sets ImageInfo to info following the rules in set_info() and allocates pixel memory.
row_bytes must equal or exceed info.width() times info.bytes_per_pixel(), or equal
None. Pass in None for row_bytes to compute the minimum valid value.
Returns false and calls reset() if ImageInfo could not be set, or memory could not be
allocated.
On most platforms, allocating pixel memory may succeed even though there is not sufficient
memory to hold pixels; allocation does not take place until the pixels are written to. The
actual behavior depends on the platform implementation of malloc().

)
pub fn alloc_pixels_info( &mut self, image_info: &Handle<SkImageInfo>, row_bytes: impl Into<Option<usize>>, )
Sets ImageInfo to info following the rules in set_info() and allocates pixel memory.
row_bytes must equal or exceed info.width() times info.bytes_per_pixel(), or equal
None. Pass in None for row_bytes to compute the minimum valid value.
Aborts execution if SkImageInfo could not be set, or memory could be allocated.

is_opaque: impl Into<Option<bool>>,
) -> bool
pub fn try_alloc_n32_pixels( &mut self, _: (i32, i32), is_opaque: impl Into<Option<bool>>, ) -> bool
Sets ImageInfo to width, height, and native color type; and allocates pixel memory. If
is_opaque is true, sets ImageInfo to AlphaType::Opaque; otherwise, sets to
AlphaType::Premul.
Calls reset() and returns false if width exceeds 29 bits or is negative, or height is
negative.
Returns false if allocation fails.
Use to create Bitmap that matches crate::PMColor, the native pixel arrangement on
the platform. Bitmap drawn to output device skips converting its pixel format.
pub fn alloc_n32_pixels(
&mut self,
_: (i32, i32),
is_opaque: impl Into<Option<bool>>,
)
pub fn alloc_n32_pixels( &mut self, _: (i32, i32), is_opaque: impl Into<Option<bool>>, )
Sets ImageInfo to width, height, and native color type; and allocates pixel memory. If
is_opaque is true, sets ImageInfo to AlphaType::Opaque; otherwise, sets to
AlphaType::Premul.
Aborts if width exceeds 29 bits or is negative, or height is negative, or allocation fails.

pixels: *mut c_void,
row_bytes: usize,
) -> bool
pub unsafe fn install_pixels( &mut self, info: &Handle<SkImageInfo>, pixels: *mut c_void, row_bytes: usize, ) -> bool
Sets ImageInfo to info following the rules in set_info(), and creates PixelRef
containing pixels and row_bytes.
If ImageInfo could not be set, or row_bytes is less than info.min_row_bytes(): calls reset(), and returns false`.
Otherwise, if pixels equals ptr::null_mut(): sets ImageInfo, returns true.
Caller must ensure that pixels are valid for the lifetime of Bitmap and PixelRef.
pub fn try_alloc_pixels(&mut self) -> bool
pub fn try_alloc_pixels(&mut self) -> bool
Allocates pixel memory with HeapAllocator, and replaces existing PixelRef. The
allocation size is determined by ImageInfo width, height, and ColorType.
Returns false if info().color_type() is ColorType::Unknown, or allocation fails.
pub fn alloc_pixels(&mut self)
pub fn alloc_pixels(&mut self)
Allocates pixel memory with HeapAllocator, and replaces existing PixelRef. The
allocation size is determined by ImageInfo width, height, and ColorType.
Aborts if info().color_type() is ColorType::Unknown, or allocation fails.
pub fn pixel_ref_origin(&self) -> IPoint
pub fn pixel_ref_origin(&self) -> IPoint
Returns origin of pixels within PixelRef. Bitmap bounds is always contained
by PixelRef bounds, which may be the same size or larger. Multiple Bitmap
can share the same PixelRef, where each Bitmap has different bounds.
The returned origin added to Bitmap dimensions equals or is smaller than the
PixelRef dimensions.
Returns (0, 0) if PixelRef is None.
pub fn set_pixel_ref(
&mut self,
pixel_ref: impl Into<Option<RCHandle<SkPixelRef>>>,
offset: impl Into<IPoint>,
)
pub fn set_pixel_ref( &mut self, pixel_ref: impl Into<Option<RCHandle<SkPixelRef>>>, offset: impl Into<IPoint>, )
Replaces pixel_ref and origin in Bitmap. offset specifies the offset within the
PixelRef pixels for the top-left corner of the bitmap.
Asserts in debug builds if offset is out of range. Pins offset to legal range in release builds.
The caller is responsible for ensuring that the pixels match the ColorType and
AlphaType in ImageInfo.
pub fn is_ready_to_draw(&self) -> bool
pub fn is_ready_to_draw(&self) -> bool
Returns true if Bitmap can be drawn.
pub fn generation_id(&self) -> u32
pub fn generation_id(&self) -> u32
pub fn notify_pixels_changed(&self)
pub fn notify_pixels_changed(&self)
Marks that pixels in PixelRef have changed. Subsequent calls to generation_id() return
a different value.
pub fn erase_color(&self, c: impl Into<Color>)
pub fn erase_color(&self, c: impl Into<Color>)
Replaces pixel values with c, interpreted as being in the sRGB ColorSpace. All pixels
contained by [bounds(&self)] are affected. If the [color_type(&self)] is
ColorType::Gray8 or ColorType::RGB565, then alpha is ignored; RGB is treated as
opaque. If [color_type(&self)] is ColorType::Alpha8, then RGB is ignored.
Input color is ultimately converted to an Color4f, so Self::erase_color_4f will have
higher color resolution.
pub fn erase_color_4f(&self, c: impl AsRef<Color4f>)
pub fn erase_color_4f(&self, c: impl AsRef<Color4f>)
Replaces pixel values with c, interpreted as being in the sRGB ColorSpace. All pixels
contained by [bounds(&self)] are affected. If the [color_type(&self)] is
ColorType::Gray8 or ColorType::RGB565, then alpha is ignored; RGB is treated as
opaque. If [color_type(&self)] is ColorType::Alpha8, then RGB is ignored.
pub fn erase_argb(&self, a: u8, r: u8, g: u8, b: u8)
pub fn erase_argb(&self, a: u8, r: u8, g: u8, b: u8)
Replaces pixel values with unpremultiplied color built from a, r, g, and b,
interpreted as being in the sRGB ColorSpace. All pixels contained by [bounds(&self)]
are affected. If the [color_type(&self)] is ColorType::Gray8 or ColorType::RGB565,
then a is ignored; r, g, and b are treated as opaque. If [color_type(&self)] is
ColorType::Alpha8, then r, g, and b are ignored.
pub fn erase(&self, c: impl Into<Color>, area: impl AsRef<IRect>)
pub fn erase(&self, c: impl Into<Color>, area: impl AsRef<IRect>)
Replaces pixel values inside area with c. interpreted as being in the sRGB ColorSpace.
If area does not intersect bounds(), call has no effect.
If the color_type() is ColorType::Gray8 ColorType::RGB565, then alpha is ignored;
RGB is treated as opaque. If color_type() is ColorType::Alpha8, then RGB is ignored.
Input color is ultimately converted to an Color4f, so Self::erase_4f will have
higher color resolution.
pub fn erase_4f(&self, c: impl AsRef<Color4f>, area: impl AsRef<IRect>)
pub fn erase_4f(&self, c: impl AsRef<Color4f>, area: impl AsRef<IRect>)
Replaces pixel values inside area with c. interpreted as being in the sRGB ColorSpace.
If area does not intersect bounds(), call has no effect.
If the color_type() is ColorType::Gray8 ColorType::RGB565, then alpha is ignored;
RGB is treated as opaque. If color_type() is ColorType::Alpha8, then RGB is ignored.
pub fn get_color(&self, p: impl Into<IPoint>) -> Color
pub fn get_color(&self, p: impl Into<IPoint>) -> Color
Returns pixel at (x, y) as unpremultiplied color.
Returns black with alpha if ColorType is ColorType::Alpha8
Input is not validated: out of bounds values of x or y trigger an assert().
Fails if ColorType is ColorType::Unknown or pixel address is nullptr.
ColorSpace in ImageInfo is ignored. Some color precision may be lost in the
conversion to unpremultiplied color; original pixel data may have additional precision.
pub fn get_color_4f(&self, p: impl Into<IPoint>) -> Color4f
pub fn get_color_4f(&self, p: impl Into<IPoint>) -> Color4f
Returns pixel at (x, y) as unpremultiplied color.
Returns black with alpha if ColorType is ColorType::Alpha8
Input is not validated: out of bounds values of x or y trigger an assert().
Fails if ColorType is ColorType::Unknown or pixel address is None.
ColorSpace in ImageInfo is ignored. Some color precision may be lost in the
conversion to unpremultiplied color.
pub fn get_alpha_f(&self, p: impl Into<IPoint>) -> f32
pub fn get_alpha_f(&self, p: impl Into<IPoint>) -> f32
Look up the pixel at (x,y) and return its alpha component, normalized to [0..1]. This is
roughly equivalent to get_color().a(), but can be more efficient (and more precise if the
pixels store more than 8 bits per component).
pub fn get_addr(&self, p: impl Into<IPoint>) -> *const c_void
pub fn get_addr(&self, p: impl Into<IPoint>) -> *const c_void
Returns pixel address at (x, y).
Input is not validated: out of bounds values of x or y, or ColorType::Unknown,
trigger an assert(). Returns nullptr if ColorType is ColorType::Unknown, or
PixelRef is nullptr.
Performs a lookup of pixel size; for better performance, call one of: get_addr8(),
get_addr16(), or get_addr32().
pub fn extract_subset(
&self,
dst: &mut Handle<SkBitmap>,
subset: impl AsRef<IRect>,
) -> bool
pub fn extract_subset( &self, dst: &mut Handle<SkBitmap>, subset: impl AsRef<IRect>, ) -> bool
Shares PixelRef with dst. Pixels are not copied; Bitmap and dst point to the same
pixels; dst Self::bounds() are set to the intersection of subset and the original
Self::bounds().
Subset may be larger than Self::bounds(). Any area outside of Self::bounds() is
ignored.
Any contents of dst are discarded.
Return false if:
- dst is
nullptr PixelRefisnullptr- subset does not intersect
Self::bounds()
pub unsafe fn read_pixels(
&self,
dst_info: &Handle<SkImageInfo>,
dst_pixels: *mut c_void,
dst_row_bytes: usize,
src_x: i32,
src_y: i32,
) -> bool
pub unsafe fn read_pixels( &self, dst_info: &Handle<SkImageInfo>, dst_pixels: *mut c_void, dst_row_bytes: usize, src_x: i32, src_y: i32, ) -> bool
Copies a crate::Rect of pixels from Bitmap to dst_pixels. Copy starts at (src_x, src_y), and does not exceed Bitmap (width(), height()).
dst_info specifies width, height, ColorType, AlphaType, and ColorSpace of
destination.
dst_row_bytes specifics the gap from one destination row to the next. Returns true if
pixels are copied. Returns false if:
dst_infohas no addressdst_row_bytesis less thandst_info.min_row_bytes()PixelRefisnullptr
Pixels are copied only if pixel conversion is possible. If Self::color_type() is
ColorType::Gray8, or ColorType::Alpha8; dst_info.color_type() must match. If
Self::color_type() is ColorType::Gray8, dst_info.color_space() must match. If
Self::alpha_type() is AlphaType::Opaque, dst_info.alpha_type() must match. If
Self::color_space() is nullptr, dst_info.color_space() must match. Returns false
if pixel conversion is not possible.
src_x and src_y may be negative to copy only top or left of source. Returns false if
Self::width() or Self::height() is zero or negative. Returns false if abs(src_x)
=
Self::width(), or ifabs(src_y)>=Self::height().
pub fn extract_alpha(
&self,
dst: &mut Handle<SkBitmap>,
paint: Option<&Handle<SkPaint>>,
) -> Option<IPoint>
pub fn extract_alpha( &self, dst: &mut Handle<SkBitmap>, paint: Option<&Handle<SkPaint>>, ) -> Option<IPoint>
Sets dst to alpha described by pixels. Returns false if dst cannot be written to or
dst pixels cannot be allocated.
If paint is not None and contains crate::MaskFilter, crate::MaskFilter generates
mask alpha from Bitmap. Uses HeapAllocator to reserve memory for dst PixelRef.
Returns offset to top-left position for dst for alignment with Bitmap; (0, 0) unless
crate::MaskFilter generates mask.

§impl Handle<SkPath>
impl Handle<SkPath>
Path contain geometry. Path may be empty, or contain one or more verbs that
outline a figure. Path always starts with a move verb to a Cartesian coordinate,
and may be followed by additional verbs that add lines or curves.
Adding a close verb makes the geometry into a continuous loop, a closed contour.
Path may contain any number of contours, each beginning with a move verb.
Path contours may contain only a move verb, or may also contain lines,
quadratic beziers, conics, and cubic beziers. Path contours may be open or
closed.
When used to draw a filled area, Path describes whether the fill is inside or
outside the geometry. Path also describes the winding rule used to fill
overlapping contours.
Internally, Path lazily computes metrics likes bounds and convexity. Call
Path::update_bounds_cache to make Path thread safe.
pub fn new_from(
points: &[Point],
verbs: &[u8],

) -> Handle<SkPath>
pub fn new_from( points: &[Point], verbs: &[u8], conic_weights: &[f32], fill_type: SkPathFillType, is_volatile: impl Into<Option<bool>>, ) -> Handle<SkPath>
Create a new path with the specified segments.
The points and weights arrays are read in order, based on the sequence of verbs.
Move 1 point Line 1 point Quad 2 points Conic 2 points and 1 weight Cubic 3 points Close 0 points
If an illegal sequence of verbs is encountered, or the specified number of points or weights is not sufficient given the verbs, an empty Path is returned.
A legal sequence of verbs consists of any number of Contours. A contour always begins with a Move verb, followed by 0 or more segments: Line, Quad, Conic, Cubic, followed by an optional Close.

pub fn interpolate(
&self,
ending: &Handle<SkPath>,
weight: f32,
) -> Option<Handle<SkPath>>
pub fn interpolate( &self, ending: &Handle<SkPath>, weight: f32, ) -> Option<Handle<SkPath>>
Interpolates between Path with Point array of equal size.
Copy verb array and weights to out, and set out Point array to a weighted
average of this Point array and ending Point array, using the formula:
(Path Point * weight) + ending Point * (1 - weight).
weight is most useful when between zero (ending Point array) and
one (this Point_Array); will work with values outside of this
range.
interpolate() returns false and leaves out unchanged if Point array is not
the same size as ending Point array. Call is_interpolatable() to check Path
compatibility prior to calling interpolate().
pub fn fill_type(&self) -> SkPathFillType
pub fn fill_type(&self) -> SkPathFillType
Returns PathFillType, the rule used to fill Path.
Returns: current PathFillType setting
pub fn set_fill_type(&mut self, ft: SkPathFillType) -> &mut Handle<SkPath>
pub fn set_fill_type(&mut self, ft: SkPathFillType) -> &mut Handle<SkPath>

that ft is legal, values outside of FillType are not supported.
pub fn is_inverse_fill_type(&self) -> bool
pub fn is_inverse_fill_type(&self) -> bool
Returns if FillType describes area outside Path geometry. The inverse fill area
extends indefinitely.
Returns: true if FillType is InverseWinding or InverseEvenOdd
pub fn toggle_inverse_fill_type(&mut self) -> &mut Handle<SkPath>
pub fn toggle_inverse_fill_type(&mut self) -> &mut Handle<SkPath>

pub fn reset(&mut self) -> &mut Handle<SkPath>
pub fn reset(&mut self) -> &mut Handle<SkPath>
pub fn rewind(&mut self) -> &mut Handle<SkPath>
pub fn rewind(&mut self) -> &mut Handle<SkPath>
Sets Path to its initial state, preserving internal storage.
Removes verb array, Point array, and weights, and sets FillType to Winding.
Internal storage associated with Path is retained.
Use rewind() instead of reset() if Path storage will be reused and performance
is critical.
Returns: reference to Path
pub fn is_last_contour_closed(&self) -> bool
pub fn is_last_contour_closed(&self) -> bool
Returns if contour is closed.
Contour is closed if Path Verb array was last modified by close(). When stroked,
closed contour draws crate::paint::Join instead of crate::paint::Cap at first and last Point.
Returns: true if the last contour ends with a Verb::Close
example: https://fiddle.skia.org/c/@Path_isLastContourClosed
pub fn is_volatile(&self) -> bool
pub fn is_volatile(&self) -> bool
Returns true if the path is volatile; it will not be altered or discarded
by the caller after it is drawn. Path by default have volatile set false, allowing
crate::Surface to attach a cache of data which speeds repeated drawing. If true, crate::Surface
may not speed repeated drawing.
Returns: true if caller will alter Path after drawing
pub fn set_is_volatile(&mut self, is_volatile: bool) -> &mut Handle<SkPath>
pub fn set_is_volatile(&mut self, is_volatile: bool) -> &mut Handle<SkPath>
Specifies whether Path is volatile; whether it will be altered or discarded
by the caller after it is drawn. Path by default have volatile set false, allowing
Device to attach a cache of data which speeds repeated drawing.
Mark temporary paths, discarded or modified after use, as volatile
to inform Device that the path need not be cached.
Mark animating Path volatile to improve performance.
Mark unchanging Path non-volatile to improve repeated rendering.
raster surface Path draws are affected by volatile for some shadows.
GPU surface Path draws are affected by volatile for some shadows and concave geometries.

pub fn swap(&mut self, other: &mut Handle<SkPath>) -> &mut Handle<SkPath>
pub fn swap(&mut self, other: &mut Handle<SkPath>) -> &mut Handle<SkPath>
Exchanges the verb array, Point array, weights, and FillType with other.
Cached state is also exchanged. swap() internally exchanges pointers, so
it is lightweight and does not allocate memory.
swap() usage has largely been replaced by PartialEq.
Path do not copy their content on assignment until they are written to,
making assignment as efficient as swap().

pub fn bounds(&self) -> &Rect
pub fn bounds(&self) -> &Rect
Returns minimum and maximum axes values of Point array.

Verb::Move that define empty contours.
pub fn update_bounds_cache(&mut self) -> &mut Handle<SkPath>
pub fn update_bounds_cache(&mut self) -> &mut Handle<SkPath>
Updates internal bounds so that subsequent calls to bounds() are instantaneous.
Unaltered copies of Path may also access cached bounds through bounds().
For now, identical to calling bounds() and ignoring the returned value.
Call to prepare Path subsequently drawn from multiple threads,
to avoid a race condition where each draw separately computes the bounds.
pub fn compute_tight_bounds(&self) -> Rect
pub fn compute_tight_bounds(&self) -> Rect

contours.
Behaves identically to bounds() when Path contains
only lines. If Path contains curves, computed bounds includes
the maximum extent of the quad, conic, or cubic; is slower than bounds();
and unlike bounds(), does not cache the result.
Returns: tight bounds of curves in Path
pub fn conservatively_contains_rect(&self, rect: impl AsRef<Rect>) -> bool
pub fn conservatively_contains_rect(&self, rect: impl AsRef<Rect>) -> bool
Returns true if rect is contained by Path.

If Path is empty, or last Verb
is Verb::Close, last point is set to (0, 0) before adding cubic.
Appends Verb::Move to verb array and (0, 0) to Point array,
if needed; then appends Verb::Cubic to verb array; and appends cubic
control and cubic end to Point array.
Cubic control is last point plus vector (dx1, dy1).
Cubic end is last point plus vector (dx2, dy2).
Function name stands for “relative cubic to”.

pub fn arc_to( &mut self, oval: impl AsRef<Rect>, start_angle: f32, sweep_angle: f32, force_move_to: bool, ) -> &mut Handle<SkPath>
Appends arc to Path. Arc added is part of ellipse
bounded by oval, from start_angle through sweep_angle. Both start_angle and
sweep_angle are measured in degrees, where zero degrees is aligned with the
positive x-axis, and positive sweeps extends arc clockwise.
arc_to() adds line connecting Path last Point to initial arc Point if force_move_to
is false and Path is not empty. Otherwise, added contour begins with first point
of arc. Angles greater than -360 and less than 360 are treated modulo 360.

pub fn arc_to_tangent( &mut self, p1: impl Into<Point>, p2: impl Into<Point>, radius: f32, ) -> &mut Handle<SkPath>
Appends arc to Path, after appending line if needed. Arc is implemented by conic
weighted to describe part of circle. Arc is contained by tangent from
last Path point to (x1, y1), and tangent from (x1, y1) to (x2, y2). Arc
is part of circle sized to radius, positioned so it touches both tangent lines.
If last Path Point does not start Arc, arc_to appends connecting Line to Path.
The length of Vector from (x1, y1) to (x2, y2) does not affect Arc.
Arc sweep is always less than 180 degrees. If radius is zero, or if
tangents are nearly parallel, arc_to appends Line from last Path Point to (x1, y1).
arc_to_tangent appends at most one Line and one conic.
arc_to_tangent implements the functionality of PostScript arct and HTML Canvas arc_to.

Appends arc to Path. Arc is implemented by one or more conics weighted to
describe part of oval with radii (rx, ry) rotated by x_axis_rotate degrees. Arc
curves from last Path Point to (x, y), choosing one of four possible routes:
clockwise or counterclockwise, and smaller or larger.
Arc sweep is always less than 360 degrees. arc_to_rotated() appends line to (x, y) if
either radii are zero, or if last Path Point equals (x, y). arc_to_rotated() scales radii
(rx, ry) to fit last Path Point and (x, y) if both are greater than zero but
too small.
arc_to_rotated() appends up to four conic curves.
arc_to_rotated() implements the functionality of SVG arc, although SVG sweep-flag value
is opposite the integer value of sweep; SVG sweep-flag uses 1 for clockwise,
while Direction::CW cast to int is zero.

Appends arc to Path, relative to last Path Point. Arc is implemented by one or
more conic, weighted to describe part of oval with radii (r.x, r.y) rotated by
x_axis_rotate degrees. Arc curves from last Path Point to relative end Point:
(dx, dy), choosing one of four possible routes: clockwise or
counterclockwise, and smaller or larger. If Path is empty, the start arc Point
is (0, 0).
Arc sweep is always less than 360 degrees. arc_to() appends line to end Point
if either radii are zero, or if last Path Point equals end Point.
arc_to() scales radii (rx, ry) to fit last Path Point and end Point if both are
greater than zero but too small to describe an arc.
arc_to() appends up to four conic curves.

pub fn close(&mut self) -> &mut Handle<SkPath>
pub fn close(&mut self) -> &mut Handle<SkPath>
Appends Verb::Close to Path. A closed contour connects the first and last Point
with line, forming a continuous loop. Open and closed contour draw the same
with fill style. With stroke style, open contour draws
crate::paint::Cap at contour start and end; closed contour draws
crate::paint::Join at contour start and end.
close() has no effect if Path is empty or last Path Verb is Verb::Close.
Returns: reference to Path

pub fn convert_conic_to_quads( p0: impl Into<Point>, p1: impl Into<Point>, p2: impl Into<Point>, w: f32, pts: &mut [Point], pow2: usize, ) -> Option<usize>
Approximates conic with quad array. Conic is constructed from start Point p0,
control Point p1, end Point p2, and weight w.
Quad array is stored in pts; this storage is supplied by caller.
Maximum quad count is 2 to the pow2.
Every third point in array shares last Point of previous quad and first Point of
next quad. Maximum pts storage size is given by:
(1 + 2 * (1 << pow2)) * sizeof(Point).
Returns quad count used the approximation, which may be smaller than the number requested.
conic weight determines the amount of influence conic control point has on the curve. w less than one represents an elliptical section. w greater than one represents a hyperbolic section. w equal to one represents a parabolic section.
Two quad curves are sufficient to approximate an elliptical conic with a sweep of up to 90 degrees; in this case, set pow2 to one.
pub fn is_rect(&self) -> Option<(Rect, bool, SkPathDirection)>
pub fn is_rect(&self) -> Option<(Rect, bool, SkPathDirection)>
Returns Some(Rect, bool, PathDirection) if Path is equivalent to Rect when filled.
If false: rect, is_closed, and direction are unchanged.
If true: rect, is_closed, and direction are written to.
rect may be smaller than the Path bounds. Path bounds may include Verb::Move points
that do not alter the area drawn by the returned rect.
Returns: Some(rect, is_closed, direction) if Path contains Rect

) -> &mut Handle<SkPath>
pub fn add_rect( &mut self, rect: impl AsRef<Rect>, dir_start: Option<(SkPathDirection, usize)>, ) -> &mut Handle<SkPath>
Adds a new contour to the path, defined by the rect, and wound in the specified direction. The verbs added to the path will be:
Move, Line, Line, Line, Close
start specifies which corner to begin the contour: 0: upper-left corner 1: upper-right corner 2: lower-right corner 3: lower-left corner
This start point also acts as the implied beginning of the subsequent,
contour, if it does not have an explicit move_to(). e.g.
path.add_rect(...)
// if we don’t say move_to() here, we will use the rect’s start point

) -> &mut Handle<SkPath>
pub fn add_oval( &mut self, oval: impl AsRef<Rect>, dir_start: Option<(SkPathDirection, usize)>, ) -> &mut Handle<SkPath>
Adds oval to Path, appending Verb::Move, four Verb::Conic, and Verb::Close.
Oval is upright ellipse bounded by Rect oval with radii equal to half oval width
and half oval height. Oval begins at start and continues
clockwise if dir is Direction::CW, counterclockwise if dir is Direction::CCW.

pub fn add_open_oval( &mut self, oval: impl AsRef<Rect>, dir_start: Option<(SkPathDirection, usize)>, ) -> &mut Handle<SkPath>
Experimental, subject to change or removal.
Adds an “open” oval to Path. This follows canvas2D semantics: The oval is not
a separate contour. If the path was empty, then Verb::Move is appended. Otherwise,
Verb::Line is appended. Four Verb::Conic are appended. Verb::Close is not appended.

) -> &mut Handle<SkPath>
pub fn add_circle( &mut self, p: impl Into<Point>, radius: f32, dir: impl Into<Option<SkPathDirection>>, ) -> &mut Handle<SkPath>
Adds circle centered at (x, y) of size radius to Path, appending Verb::Move,
four Verb::Conic, and Verb::Close. Circle begins at: (x + radius, y), continuing
clockwise if dir is Direction::CW, and counterclockwise if dir is Direction::CCW.
Has no effect if radius is zero or negative.
pub fn add_arc(
&mut self,

) -> &mut Handle<SkPath>
pub fn add_arc( &mut self, oval: impl AsRef<Rect>, start_angle: f32, sweep_angle: f32, ) -> &mut Handle<SkPath>
Appends arc to Path, as the start of new contour. Arc added is part of ellipse
bounded by oval, from start_angle through sweep_angle. Both start_angle and
sweep_angle are measured in degrees, where zero degrees is aligned with the
positive x-axis, and positive sweeps extends arc clockwise.
If sweep_angle <= -360, or sweep_angle >= 360; and start_angle modulo 90 is nearly
zero, append oval instead of arc. Otherwise, sweep_angle values are treated
modulo 360, and arc may or may not draw depending on numeric rounding.

pub fn add_round_rect( &mut self, rect: impl AsRef<Rect>, _: (f32, f32), dir: impl Into<Option<SkPathDirection>>, ) -> &mut Handle<SkPath>
Appends RRect to Path, creating a new closed contour. RRect has bounds
equal to rect; each corner is 90 degrees of an ellipse with radii (rx, ry). If
dir is Direction::CW, RRect starts at top-left of the lower-left corner and
winds clockwise. If dir is Direction::CCW, RRect starts at the bottom-left
of the upper-left corner and winds counterclockwise.
If either rx or ry is too large, rx and ry are scaled uniformly until the
corners fit. If rx or ry is less than or equal to zero, add_round_rect() appends
Rect rect to Path.
After appending, Path may be empty, or may contain: Rect, oval, or RRect.

Adds rrect to Path, creating a new closed contour. If dir is Direction::CW, rrect
winds clockwise; if dir is Direction::CCW, rrect winds counterclockwise.
start determines the first point of rrect to add.

pub fn add_poly(&mut self, pts: &[Point], close: bool) -> &mut Handle<SkPath>
pub fn add_poly(&mut self, pts: &[Point], close: bool) -> &mut Handle<SkPath>
Adds contour created from line array, adding pts.len() - 1 line segments.
Contour added starts at pts[0], then adds a line for every additional Point
in pts slice. If close is true, appends Verb::Close to Path, connecting
pts[pts.len() - 1] and pts[0].
If count is zero, append Verb::Move to path.
Has no effect if ps.len() is less than one.
