I don't know if this is the most efficient way, but you could try separating the image and the alpha channel, modify the image, then recombine the alpha channel with the modified image.
convert image \ \( -clone 0 +matte -fuzz 4 % -fill "#FFFFFF" -opaque "#000000" \) \ \( -clone 0 -channel matte -separate +matte \) \ -delete 0 +matte -compose copy_opacity -composite result see http://www.imagemagick.org/Usage/compose/#copyopacity >Hi guys, > >I've a vector graphic with a single color as an png file.
