it might be useful if the color to alpha filter could a) interact with the color picker or b) pull the information about the image background from the color tool stuff and use that as the color to replace. it isnt easy for a lot of users to select the color in the color selector without being able to pull that from the image. i just told a user how to use color picker to get the color code and enter that in the selector. it works, but it would be nicer if this tool were more user-friendly. just a thought. no, i can't prrogram it myself. and no, i will not whine about this repeatedly. just trying once to be helpful. :-)
