while playing around with PNMBrush i’ve encountered a “problem”, while the blend mode works fine, the other modes confuse me.
BESet doesnt seem to do anything.
BEDarken: does darken down a area, but it stops at 0.5 (0,1,0,1) darkened by (0,0,0,0) will get you (0,.5,0,.5). i would expect it to go to fully darkened.
BELighten: the same as darken (but reversed of course).
i have only tried working with drawPoint. so i dont know if the other painting tools do it correctly.
i have also seen that painting (BEBlend) with low alpha values dont change anything anymore (im talking about values above 0.01, where it still should change colors).
i also have a feature request:
- it would be great if there were more modes. like a smoothing brush (averaging between neighbooring pixels).
