Hi, I need to make transparent some zones in an image but not others that have the same color. For example if I take logo: image (the ImageMagick wizard), I want to turn transparent all white zones but not the white beard.
In other words, I want to make transparent the background of an image but not the inner zones that have same color as background is. I try to use Masking Simple Backgrounds (floodfill) example from Anthony Thyssen's example page http://www.imagemagick.org/Usage/channels/ Below the DOS script: convert logo: ( +clone -fx "p{0,0}" ) -compose ifference -composite -modulate 100,0 +matte difference.png convert difference.png -threshold 0 boolean_mask.png convert logo: boolean_mask.png +matte -compose CopyOpacity -composite logo_boolean.png but the beard turn transparent...! Can anyone help me? Thanks in advance.
