DOH! me, slaps forehead Yea, it's there. Thanks. I fell dumb. I saw Script-Fu under Filters and I didn't even realize that it also had its own button. Thanks! So I applied the purple fringing fix, and it seems to have done a really marvelous job, but now I got a new problem. When I go to save the fixed image, I am getting a warning message saying: You are about to save a layer mask as JPEG. This will not save the visible layers. I have no idea what this means. Should I be worried? Do I have to do some other magic before I save the fixed image? Oh boy! It gets even weirder. I went ahead and clicked on Confirm and now I'm getting another warning saying: Your image should be exported before it can be saved as JPEG for the following reasons: JPEG plug-in can't handle transparency Flatten image The export conversion won't modify your original image. Hummm... OK, so now one of the options in response to that is export, so take a chance and click on that. Presto! Changeo! Well, whatever the hell all that was about, I guess it all worked. Here's the de-fringed image: ftp://ftp.tristatelogic.com/private/gimp/squirrel-c.jpg Looks OK to me. And definitely less fringe. I still worry a little about the fact that I really don't know what the hell I'm even doing. But what the hell! It wouldn't be the first time. :-) Regards, rfg P.S. This seems rather odd to me, but apparently Darla's defringer will not allow itself to be applied twice, successively, to an image. Once you have defringed using the script, you can't get the script to re-run on the same image, however... If you save the defringed image to a file, exit gimp, and then run gimp again on the defringed .JPG, then you can get the defringer to run anew. I did that, and actually, yes, the specific image I'm working with seems to have benefitted from having the defringer run on it twice. Here's the image after ONE and then TWO defringing steps: ftp://ftp.tristatelogic.com/private/gimp/squirrel-c.jpg ftp://ftp.tristatelogic.com/private/gimp/squirrel-d.jpg The fringing is most notable down at the upper edge of the rain gutter and also to the right of that, on the white stucco. Applying two defringing steps almost eliminated the fringing entirely. (Yippee!) ___ gimp-user-list mailing list gimp-user-list@gnome.org http://mail.gnome.org/mailman/listinfo/gimp-user-list

Hey Ronald, That means that your image in progress includes a layer mask, most likely added by the script you ran against it. That layer mask is the current selection. So you need to find the Layers tab in your Tool Options dock. Left click on the image part of any layer there - that would be any thumbnail that is in the left column - to select it. Now your image will save as JPG without complaint. P.S. This seems rather odd to me, but apparently Darla's defringer will not allow itself to be applied twice, successively, to an image. Once you have defringed using the script, you can't get the script to re-run on the same image, however... If you save the defringed image to a file, exit gimp, and then run gimp again on the defringed .JPG, then you can get the defringer to run anew. That's the same problem again: After running the plugin, it apparently leaves a layer mask selected. Many scripts won't run with a layer mask selected, or at all on a layer with a mask. The same filter can't run against the finished result you see in the main image edit window, because what you are looking at is the base layer, with its appearance changed by the masked layer the script left above it. It may be possible to select the base layer in the Layers tab of your tool options dock, and run the filter against that layer. If this works it will give you an additive effect from both sets of new layers + masks created by the filter. Or you can do Edit Copy Visible followed by Edit Paste, and click on the CReate a new layer button in the Layers tab of your dock window, to get what you see as one layer. You can re-run your filter against that layer. Or you can do the quick and dirty version: Do Image Flatten Image. That will get you a one layer image, where the base layer looks exactly like what your multi-layer image did moments before. Your filter will run against that for sure. I did that, and actually, yes, the specific image I'm working with seems to have benefitted from having the defringer run on it twice. Here's the image after ONE and then TWO defringing steps: ftp://ftp.tristatelogic.com/private/gimp/squirrel-c.jpg ftp://ftp.tristatelogic.com/private/gimp/squirrel-d.jpg As a general rule, it's not a good idea to edit, save, open, and re-edit a .jpg image. The .jpg format is a lossy compressed format: It sacrifices a small amount of detail to make the saved image a much smaller file. How much detail you lose can be adjusted during save with the Quality slider in the GIMP, but even 100% involves some loss: Every time a .jpg is opened and re-saved as .jpg, some loss of resolution happens. Just doing this once, while saving with a high quality setting, does not usually have a noticeable effect, but multiple cycles of save - close - reopen - save can add up to a messed up image, and it gets worse faster, the more you compress the image (= the lower the quality setting). It is better to save your finished image in .xcf then as .jpg, and if you need to work on it some more, start with the saved .xcf file. The .xcf format uses lossless compression, so you can save it as many times over as required without any problems. I understand the next generation of the GIMP will have separate Save and Export commands, where Save creates an .xcf file and Export creates the other format of your choice. :o) Steve ___ gimp-user-list mailing list gimp-user-list@gnome.org http://mail.gnome.org/mailman/listinfo/gimp-user-list

If I was doing this professionally, or for publication, then I would have been more careful and saved the intermediate result as a .XCF file. But I'm just messing around here, trying to see what this whiz-bang purple de-fringer can really do. And so far, I'm pretty damned impressed. It really does a nice job... even better if you run it twice. Regards, rfg ___ gimp-user-list mailing list gimp-user-list@gnome.org http://mail.gnome.org/mailman/listinfo/gimp-user-list
