Frag selects the fragment shader that colors a covered pixel.

Variants

Solid

Image

ImageMatrix

Direct-image color filters run after texture sampling.

ImageBlend

Linear

Radial

Sweep

BlendSolid

Advanced blend, solid src × dst snapshot (group1 = snapshot).

BlendTexture

Advanced blend, texture src (layer / desugared draw) × dst snapshot (group1 = snapshot + src texture).

RRectBlur

Closed-form blurred solid (r)rect — soft coverage, zero filter passes.

Blur

One direction of a separable gaussian (filter passes only).

MaskCombine

Blur style combine: blurred layer × sharp layer → one texture (filter passes only; blend layout: 0 = blurred, 2 = sharp).

DropShadow

Drop-shadow combine: the sharp layer over its offset blurred shadow (filter passes only; blend layout: 0 = shadow, 2 = sharp).

MaskComposite

Mask layer composite: texture → coverage in alpha (luminance or alpha per payload flag), drawn with DstIn.

LinearRamp

Gradients past 8 stops sampling a baked 1D ramp texture.

RadialRamp

SweepRamp

ColorMatrix

Colour filters over a layer’s texture (filter passes only): a 4×5 matrix, or a constant colour blended as the source.

ColorBlend

Pattern

An image tiled across the shape, sampled through the paint’s own local matrix — Canvas2D’s pattern.
