Isn't it better to upscale pictures using Gimp's bicubic interpolation prior to printing on a high resolution print device? Rather than relying on gimp-print? Or is gimp-print using as sophisticated an algorithm (or perhaps exactly the same algorithm) at print time? ___ Gimp-developer mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-developer

It might improve quality if you have some kind of printing mechanism that upscales by pixel replication or something. Then upscaling in GIMP with bicubic interpolation might very well improve the quality of the resulting image. Agreed you cannot add useful information - but having a fuzzy image is generally better than having a pixellated image.

What does Genuine Fractals do? Please do not expect us to know every graphics tool and plug-in that is out there. I briefly looked at their web page, but that seem to be squarely aimed at artists, with only a few examples. -- branko collin [EMAIL PROTECTED] ___ Gimp-developer mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-developer

What are you expecting by upscaling pictures? Why do you do that? It will definitely not improve quality as there is no gain in information. Just enter your favorite size in /Image/Scale Image in section "Print Size & Display Unit". HTH!
