The image has a white background (color?), and I would like to replace the white color with transparent color.
(I think it is white

Is it possible with ImageMagick?

Thank you!fmw42 wrote:convert image -fuzz XX% -transparent white result
XX is tolerance to match white, try 5% ......
Good idea!fmw42 wrote:If the image is white at 0,0 (or any other pixel you want to identify), then try
convert image -fill none -fuzz 20% -draw 'matte 0,0 floodfill' result.png
This will floodfill the outside with transparency and not touch inside areas that are near white.
Again adjust the fuzz value as desired.
