Perl-o-tine filter and JPEG image quality

Hi! Is there a way to control the JPEG image quality settings for the JPEG images that can be generated by the "Perl-o-tine" filter? I'm finding the quality of the JPEGs that are generated by the filter are of lower quality than the source JPEG or XCF file used as the source for the "Perl-o-tine" filter.

I'm using Gimp 1.2.5 on Slackware 8 Linux.

Thanks!

Peace...

Tom

We're having the same problem with gimp on Red Hat. I would love it if someone would take the time to update this feature and I'm sure a lot of the end users would particularly appreciate it too. Our designers end up doing these things by hand or using external tools which seems like such a waste since perl-o-tine is so close to making this really pain-free to do entirely within gimp.

Of course there's a way. Modify the source of perlotine so that it doesn't call the general gimp_file_save() function but uses file_jpeg_save() explicitely. The latter function gives you fine-grained control over the JPEG save parameters such as the quality setting.
