Hi, When I use a gimp_file_load followed by a gimp_file_save in perl script with a jpg for instance, it doesn't work ... What method should I use to have a "transparent" process about the format (I don't mean indexed/others but simply RGB-layer merged pictures of any fmt). gimp_file_save as explained in PDB ought to look for the right method ... ($img->layer)[0]->gimp_jpeg_save() for instance (using source compression level and so on). Regards, Fabian -- Sent through GMX FreeMail - http://www.gmx.net
