pub fn read_pixels<P>( &self, dst_info: &Handle<SkImageInfo>, pixels: &mut [P], dst_row_bytes: usize, src: impl Into<IPoint>, ) -> bool

pub fn bytes(&self) -> Option<&'pixels [u8]>

Access the underlying pixels as a byte array. This is a rust-skia specific function.

pub fn bytes_mut(&mut self) -> Option<&'pixels mut [u8]>

pub fn pixels<P>(&self) -> Option<&'pixels [P]>

where P: Pixel,

Access the underlying pixels. This is a rust-skia specific function.

The Pixel type must implement the unsafe trait Pixel and must return true in Pixel::matches_color_type() when matched against the ColorType of this Pixmap’s pixels.

impl Pixmap<'_>

pub fn encode( &self, format: SkEncodedImageFormat, quality: impl Into<Option<u32>>, ) -> Option<Vec<u8>>

Trait Implementations

impl Debug for Pixmap<'_>

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.
