Struct DecodedLayer 

pub struct DecodedLayer {
    pub pixels: Vec<u8>,
    pub tag: Option<u8>,
}

A decoded layer mask.

Fields

pixels: Vec<u8>

One byte per pixel, in row-major order, total_pixels long.

tag: Option<u8>

The tag the stream carried, or None for the empty-layer form.

Implementations

impl DecodedLayer

pub fn empty(total_pixels: u32) -> DecodedLayer

All-black layer, carrying no stream: every LTBL entry of the layer has data_size == 0.

pub fn is_empty(&self) -> bool

Whether this is the empty-layer form.

pub fn is_binary(&self) -> bool

Whether every pixel is 0x00 or 0xFF.
