Something about Advanced Sharpen
Posted: April 14th, 2019, 10:36 am
1. Open Advanced Sharpen, go to Sharpen tab, set Radius to show some histogram, set Sharpen Amount and click Compute entire output image
2. Change either Sharpen Radius or Sharpen Amount sliders -> the histogram disappears
3. Move either again and histogram reappears
This does not happen with Noise Reduction
------
When Advanced Sharpen is reopened, edited but cancelled, it still recomputes.
------
Two optimization questions
1. If the Compute entire output image button is followed by OK or Apply, is it necessary to recompute?
2. Dragging transformations dialogs by their title bar triggers some kind of fast recalculation as their operation status bars appear in fast succession. Why is this happening when they have the Compute entire output image button to synchronize the previews?
With the other dialogs there is just a blink of the preview title bars as mouse grabs their dialog title bar.
