Replace
Replaces all pixels the color of the point clicked with Paint Color. Optional channel
Replace Transparent
Changes any pixel that matches color with the color defined by fill with option to change its transparecy. Enter transparent as the paint color or 0 for the alpha to make the target color transparent.
Color Flood Fill
Changes the color value of any pixel that matches target and is an immediate neighbor to Paint Color until Border Color is encountered.
Alpha
The level of transparency: 1.0 is fully opaque and 0.0 is fully transparent.
Paint Flood Fill
Changes the color value of any pixel that matches the point clicked and is an immediate neighbor to Paint Color while Border Color is matched.
Set Opacity
For PNG's. Sets the image to the specified opacity level. Set Alpha. Click anywhere on image
Channel
Color channel
Fuzz
The fuzz member of image defines how much tolerance is acceptable to consider two colors as the same.
