Struct GpuFilterData 

pub struct GpuFilterData { /* private fields */ }

A filter’s parameter block with its kind erased, as it is serialized into the filter-data texture.

Every kind casts to this because every kind is FILTER_SIZE_BYTES wide; the fragment stage reads the kind back out of the header.

Implementations

impl GpuFilterData

pub const SIZE_TEXELS: u32

Texels one parameter block occupies in the filter-data texture — the stride a filter’s own texel offset is a multiple of.

pub fn filter_type(&self) -> u32

The filter kind the header names, one of filter_type’s constants.

pub fn n_decimations(&self) -> usize

How many 2x decimation levels the header names, meaningful for a blur.

pub fn words(&self) -> &[u32; 12]

The block’s words, in the order they are uploaded.
