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