What is the GraphicsMagick equivalent of ImageMagick's +opaque?
Extracting a specific color (red) from an indexed BMP in ImageMagick goes like this:
convert input.bmp +opaque "#FF0000" red.png
Trying it with GraphicsMagick fails as it appears to not support +opaque, only -opaque.
How does one do the equivalent with GraphicsMagick? Perhaps there is a cheatsheet for migrating from ImageMagick to GraphicsMagick?
