Struct exr::block::chunk::CompressedScanLineBlock

source ·
pub struct CompressedScanLineBlock {
    pub y_coordinate: i32,
    pub compressed_pixels: Vec<u8>,
}
Expand description

A Block of possibly compressed flat scan lines. Corresponds to type attribute scanlineimage.

Fields§

§y_coordinate: i32

The block’s y coordinate is the pixel space y coordinate of the top scan line in the block. The top scan line block in the image is aligned with the top edge of the data window.

§compressed_pixels: Vec<u8>

One or more scan lines may be stored together as a scan line block. The number of scan lines per block depends on how the pixel data are compressed. For each line in the tile, for each channel, the row values are contiguous.
