Struct exr::image::read::specific_channels::OptionalSampleReader

source · 
pub struct OptionalSampleReader<DefaultSample> {
    reader: Option<SampleReader<DefaultSample>>,
    default_sample: DefaultSample,
}
Expand description

Reader for a single channel. Generic over the concrete sample type (f16, f32, u32). Can also skip reading a channel if it could not be found in the image.
