Unsharp-mask. Unsharp masks the layer or the final view image, after all scaling, if layer=comp.
The parameters are assumed to apply to the full resolution image and are scaled down when processing a downsampled image.

amount |
Filter strength factor (real 0…5). |
radius |
Filter kernel radius in pixels (real 0…250). |
threshold |
Filter threshold level (int 0…255). |
monochrome |
Set to 0 to apply to each color component separately or to 1 to apply only to the image brightness (intensity). monochrome is ignored for grayscale images. |
The layer mask or composite mask is sharpened as well.
Layer attribute or view attribute. Applies to the current layer or to the final view image if layer=comp
. Ignored by effect layers.
op_usm=0,0,0,0
for no unsharp-masking effect.
