Transpcolor option issue [Solved]

[koala76]

Hi,

I try to remove the white background of a picture to make it transparent but the transpcolor option has no effect.
nconvert -out png -o temp2.png -truecolors -transpcolor 255 255 255 temp.jpg

Please see the example file in attachment.

Regards

Try this:
-truecolors -set_alpha -transpcolor 255 255 255 -out png -o temp2.png temp.jpg

Thanks, it works now !
