Struct CapturedImage 

pub struct CapturedImage {
    pub width: u32,
    pub height: u32,
    pub rgba: Vec<u8>,
}

Decoded RGBA8 image.

Fields

width: u32

Width in pixels.

height: u32

Height in pixels.

rgba: Vec<u8>

Tightly-packed RGBA8 pixels, row-major (width * height * 4 bytes).

Implementations

impl CapturedImage

pub fn pixel(&self, x: u32, y: u32) -> Option<[u8; 4]>

The RGBA bytes of the pixel at (x, y), or None if out of bounds.

pub fn crop(&self, rect: Region) -> CapturedImage

Crop to rect (in this image’s pixel space), clamped to the bounds. Returns the overlapping sub-image; empty (0×0) if there is no overlap.

pub fn blit_into( &self, dst: &mut [u8], dst_w: u32, dst_h: u32, at_x: i32, at_y: i32, )

Composite this image into a dst_w × dst_h RGBA8 buffer at (at_x, at_y), clipping to the destination. Used to stitch per-output captures into one multi-output region.
