1999
Description
Powerful sharpening
filter, accurate round-off and calculation in 31 bit integer space.
Selection Dropdown
Amount X1,
this is the normal setting. Amount 500% is approximately equal
to Photoshop USM at amount=500%, radius=0.5 and threshold=0. But it produces
better quality especially in the shadows.
Amount X10,
for very low-noise images (and screen captures) there is often a need for
for stronger sharpening that the Photoshop USM allows.
Check Boxes
0/255 Inv
This is a preview
function. When enabled it will give visual feedback for pixels that have
channel value 0 or 255. This greatly helps in setting the black-point and
white-point accurately. Slowly enable/disable the 0/255 Inv
check-box to see the effect.
Sliders
Amount, 0....1000%.
This is multiplied by 10 when Amount X10 is selected in the drop-down.
