Enum PixelFormat 

pub enum PixelFormat {
    Rgb888,
    Bgr888,
    Rgba8888,
    Bgra8888,
    Xrgb8888,

    Rgb565,
    Bgrx8888,
    Gray8,
    Xbgr8888,
    Abgr8888,
}

Canonical pixel format descriptor.

This is the single source of truth for pixel formats across all subsystems (drivers, video, graphics acceleration, Wayland buffers).

Implementations

impl PixelFormat

pub fn bytes_per_pixel(&self) -> usize

Number of bytes per pixel.

pub fn bpp(&self) -> u32

Bytes per pixel (alias for bytes_per_pixel, returns u32).

pub fn has_alpha(&self) -> bool

Whether this format carries an alpha channel.

pub fn from_wl_format(code: u32) -> Option<Self>

Convert a Wayland wl_shm format code to our enum.

pub fn to_wl_format(self) -> u32

Convert our format to the Wayland wl_shm format code.

Trait Implementations

impl Clone for PixelFormat

fn clone(&self) -> PixelFormat

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PixelFormat

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

Formats the value using the given formatter.

impl PartialEq for PixelFormat

fn eq(&self, other: &PixelFormat) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for PixelFormat

impl Eq for PixelFormat

impl StructuralPartialEq for PixelFormat
