Inputs¶
Input | Description | Optional |
---|---|---|
Source | No | |
Mask | Yes |
Controls¶
Parameter / script name | Type | Default | Function |
---|---|---|---|
Colors / colors |
Double | 16 | Number of color levels to use per channel. |
Dither / dither |
Choice | None | Dithering method to apply in order to avoid the banding effect.
None (none): No dithering (posterize), creating abrupt changes.
Ordered (Bayer 2x2) (bayer2x2): Ordered dithering using a 2x2 Bayer matrix.
Ordered (Bayer 4x4) (bayer4x4): Ordered dithering using a 4x4 Bayer matrix.
Ordered (Bayer 8x8) (bayer8x8): Ordered dithering using a 8x8 Bayer matrix.
Ordered (void-and-cluster 14x14) (vac14x14): Ordered dithering using a void-and-cluster 14x14 matrix.
Ordered (void-and-cluster 25x25) (vac25x25): Ordered dithering using a void-and-cluster 25x25 matrix.
Random (random): Random dithering.
|
Seed / seed |
Integer | 2000 | Random seed: change this if you want different instances to have different dithering (only for random dithering). |
Static Seed / staticSeed |
Boolean | Off | When enabled, the dither pattern remains the same for every frame producing a constant dither effect. |
(Un)premult / premult |
Boolean | Off | Divide the image by the alpha channel before processing, and re-multiply it afterwards. Use if the input images are premultiplied. |
Invert Mask / maskInvert |
Boolean | Off | When checked, the effect is fully applied where the mask is 0. |
Mix / mix |
Double | 1 | Mix factor between the original and the transformed image. |
