Struct AnyChannel
pub struct AnyChannel<Samples> { pub name: Text, pub sample_data: Samples, pub quantize_linearly: bool, pub sampling: Vec2<usize> }A single arbitrary channel.
Samples can currently only be FlatSamples or Levels<FlatSamples>
Fields
name: TextOne of "R", "G", or "B" most of the time.
sample_data: SamplesThe actual pixel data. Can be
FlatSamplesorLevels<FlatSamples>.quantize_linearly: boolThis attribute only tells lossy compression methods whether this value should be quantized exponentially or linearly.
Should be
falsefor red, green, blue and luma channels, as they are not perceived linearly. Should betruefor hue, chroma, saturation, and alpha channels.sampling: Vec2<usize>How many of the samples are skipped compared to the other channels in this layer.
Can be used for chroma subsampling for manual lossy data compression. Values other than 1 are allowed only in flat, scan-line based images. If an image is deep or tiled, the sampling rates for all of its channels must be 1.
Implementations
impl<'s, SampleData: 's> AnyChannel<SampleData>
fn new(name: impl Into<Text>, sample_data: SampleData) -> Self where SampleData: WritableSamples<'s>,Create a new channel without subsampling.
Automatically flags this channel for specialized compression if the name is "R", "G", "B", "Y", or "L", as they typically encode values that are perceived non-linearly. Construct the value yourself using
AnyChannel { .. }, if you want to control this flag.
