SpotTintFunction

Struct SpotTintFunction 

Source
pub struct SpotTintFunction {
    pub input_dim: usize,
    pub samples_per_dim: usize,
    pub cmyk_samples: Arc<Vec<f64>>,
}
Expand description

A spot/DeviceN tint transform reduced to a uniform sampled grid.

Carries enough information for the PDF writer to round-trip the source’s /ColorSpace [/Separation … <tintFunc>] or /ColorSpace [/DeviceN … <tintFunc>] dictionary as a SampledFunction without losing the spot identity.

Fields§

§input_dim: usize

Number of input channels (1 for Separation, N for DeviceN).

§samples_per_dim: usize

Samples per input dimension. For Separation this is the length of samples / 4. For DeviceN this is the per-axis count of a grid of total size samples_per_dim.pow(input_dim).

§cmyk_samples: Arc<Vec<f64>>

Flat row-major grid of CMYK output samples, length samples_per_dim^input_dim * 4. The reader builds this by evaluating the source PDF’s tint function at uniform input points; the writer emits it back as a FunctionType-0 /Function.
