[magick-users] Composing Tif-files

[Fred Weinhaus]

To use transparency, you probably need to convert to png


convert image1.tif -fill cyan -opaque black image1_cyan.png
convert image2.tif -fill magenta -opaque black -transparent white 
image2_magenta.png
convert image3.tif -fill yellow -opaque black -transparent white 
image3_yellow.png
convert image4.tif -transparent white image4_transparent.png
