Type Alias exr::block::lines::LineRefMut

pub type LineRefMut<'s> = LineSlice<&'s mut [u8]>;

A reference to a single mutable line of pixels. May go across the whole image or just a tile section of it.

This line contains a mutable slice that all samples will be written to.

Aliased Type

struct LineRefMut<'s> {
    pub location: LineIndex,
    pub value: &'s mut [u8],
}

Fields

location: LineIndex

Where this line is located inside the image.

value: &'s mut [u8]

The raw bytes of the pixel line, either &[u8] or &mut [u8]. Must be re-interpreted as slice of f16, f32, or u32, according to the channel data type.

Implementations

impl<'s> LineRefMut<'s>

pub fn write_samples_from_slice<T: Data>(self, slice: &[T]) -> UnitResult

Writes the samples (f16, f32, u32 values) into this line value reference. Use write_samples if there is not slice available.

pub fn write_samples<T: Data>( self, get_sample: impl FnMut(usize) -> T, ) -> UnitResult

Iterate over all samples in this line, from left to right. The supplied get_line function returns the sample value for a given sample index within the line, which starts at zero for each individual line. Use write_samples_from_slice if you already have a slice of samples.
