I can convert png transparent to png with specify background color :
nconvert -quiet -transpcolor 50 50 50 -merge_alpha -out -o test.png plein.png

but don't know how to do with eps. (ghostscript is install)
can you say me how it's possible

Thanks

Hi!
We have eps images and we need to convert them in jpeg images but keeping the transparent background color.
I have just read that It's not possible to convert an eps image to jpeg or png keeping transparent background color. That was in 2008...It is still impossible or the last version solves this problem?

Thanks in advance.

Hi Pierre!

Maybe we misunterstood each other about this issue.
What we really needed was to convert an EPS image with transparent background to a JPEG image with white background. This morning we found out the solution! The solution was to install Ghostscript!
Without Ghostscript the following instruction doesnt'work, we get an error about f the image format is wrong....
nconvert -out jpeg -o [JPEG_img] -bgcolor 255 255 255 -merge_alpha [EPS_img]

After installing Ghostscript, the same instruction works perfectly an we get a beautiful jpeg image with white background.

Thanks in advance for your help.
