Struct exr::block::chunk::CompressedDeepScanLineBlock

pub struct CompressedDeepScanLineBlock {
    pub y_coordinate: i32,
    pub decompressed_sample_data_size: usize,
    pub compressed_pixel_offset_table: Vec<i8>,
    pub compressed_sample_data: Vec<u8>,
}

This Block consists of one or more deep scan lines. Corresponds to type attribute deepscanline.

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.

decompressed_sample_data_size: usize

Count of samples.

compressed_pixel_offset_table: Vec<i8>

The pixel offset table is a list of integers, one for each pixel column within the data window. Each entry in the table indicates the total number of samples required to store the pixel in it as well as all pixels to the left of it.

compressed_sample_data: 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.
