I'm finding a way to make the solid background of an image become as transparent as possible (with little halo). ImageMagick is a powerful tool however it's not easy to use. I tried one command "convert image.jpg -bordercolor white -border 1x1 -alpha set -channel RGBA -fuzz 20% -fill none -floodfill +0+0 white -shave 1x1 image.png", which works kinda well. However, this requires me to know the exact color of the solid background while I need something to work with any background color. Anyone could help me with this? Th
