Struct FilterInstanceData 

#[repr(C)]
pub struct FilterInstanceData {
    pub source_origin: u32,
    pub source_size: u32,
    pub dest_origin: u32,
    pub dest_size: u32,
    pub dest_texture_size: u32,
    pub filter_data_offset: u32,
    pub original_size: u32,
    pub filter_pass_kind: u32,
}

One filter pass’s per-instance vertex data.

Must stay byte-compatible with FilterInstanceData in shaders/filter.wgsl. Every extent is a u16 pair packed into one word, the same packing the strip and copy instances use.

Fields

source_origin: u32

Origin of the source region inside the source page.

source_size: u32

Extent of the source region.

dest_origin: u32

Origin of the destination region inside the destination page.

dest_size: u32

Extent of the destination region.

dest_texture_size: u32

Extent of the whole destination page.

filter_data_offset: u32

Texel offset of this filter’s parameter block in the filter-data texture.

original_size: u32

Extent of the filter layer before any decimation, which bounds the transparent border a decimated pass overdraws.

filter_pass_kind: u32

Which pass of the filter’s sequence this instance runs, one of FilterPassKind::code’s values.

Implementations

impl FilterInstanceData

pub fn new( step: &FilterStep, filter_data_offset: u32, source_origin: (u16, u16), dest_origin: (u16, u16), dest_texture_size: SizeU16, original_size: SizeU16, ) -> Self

The instance running step of a filter whose parameters start at filter_data_offset, from source_origin of the source page into dest_origin of a destination page of dest_texture_size.

original_size is the filter layer’s own extent, before decimation.
