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_sharpen=0, for no sharpening effect.
Compensate for the slight blurriness caused by image resampling. We also increase the JPEG quality to avoid additional JPEG artifacts along the sharpened edges.
