Fields

color_matrix: [f32; 16]

sample_offset: [f32; 2]

The origin of the image placed in texture. Used to locate the original image position in the texture.

offset: [f32; 2]

Filter effect offset for drop-shadow etc. This offset is applied during filter convolution sampling to create displaced effects like shadows.

mask_offset: [f32; 2]

The origin of the mask layer in the texture.

kernel_size: [i32; 2]

The size of the filter kernel.

mask_head: i32

The index of the head mask layer.

composite: i32

The composite mode for filter application.

• 0 = Replace: filter result completely replaces the original content
• 1 = ExcludeSource: filter result is only applied where original alpha is 0

dummy: [f32; 2]

Explicit padding to align base_color to the 16-byte boundary required by WGSL vec4<f32>. Do NOT remove — removing this will corrupt the GPU struct layout and cause base_color to be read as zeros.

base_color: [f32; 4]

the final pix color will be color * color_matrix + base_color

Trait Implementations

impl AsBytes for FilterPrimitive

where [f32; 16]: AsBytes, [f32; 2]: AsBytes, [i32; 2]: AsBytes, i32: AsBytes, [f32; 4]: AsBytes,

fn as_bytes(&self) -> &[u8]

Gets the bytes of this value.

fn write_to(&self, bytes: &mut [u8]) -> Option<()>

Writes a copy of self to bytes.

fn write_to_prefix(&self, bytes: &mut [u8]) -> Option<()>

Writes a copy of self to the prefix of bytes.

fn write_to_suffix(&self, bytes: &mut [u8]) -> Option<()>

Writes a copy of self to the suffix of bytes.

impl Clone for FilterPrimitive

fn clone(&self) -> FilterPrimitive

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FilterPrimitive

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for FilterPrimitive

fn eq(&self, other: &FilterPrimitive) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
