Transparent color can not be kept from eps

Ok thanks but is it possible to change image color. By example say color 15 154 52 change to 45 52 15 in rgb. (convert jpg to jpg or png to png)

thanks for reply

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.
