Re: how to edit tiffs without zuking up the alpha
Your aim was to use the GIMP to crop the pictures, but did you try anything else? I tried some color related operations (color compose) and it returned "Compose: Image is not a gray image (bbp=3)". The bbp bit means bits per pixel (I think), and don't know if this has any real bearing on what your doing. I tried some other color operations, most return " operates only on RGB color drawables. To me this suggests the GIMP doesn't like something about these files, rather than a problem when saving. You must tell me what the image is supposed to be, it doesn't look very recognisable to me. My knowledge of the GIMP is not very deep, I'm not an image artist, developer or anything - I just like playing with the GIMP occasionally. Dave, you obviously know more than me but I hope my suggestions help guide you in the right direction. __ Do You Yahoo!? Send instant messages with Yahoo! Messenger. http://im.yahoo.com/

If you really can't load it at all, try http://24.16.52.60/~dm/before.xcf This seems identical to what I get in memory after loading http://24.16.52.60/~dm/before.tif All my gnuish utilities complain slightly about before.tif: /net/home/dm/public_html/before.tif: Warning, incorrect count for field "MinSampleValue" (1, expecting 4); tag ignored. /net/home/dm/public_html/before.tif: Warning, incorrect count for field "MaxSampleValue" (1, expecting 4); tag ignored. But that's it, and the image looks fine. I have come to expect those warnings after years of seeing it. Hm, it is a good point that gimp-created-alphad-tiffs load with completely different channels, appearance, etc than these photoshop tiffs. Either Photoshop is screwing up the save, or Gimp is subtly screwing up the load, or Gimp is screwing up the save. How to tell which one is the case?
Re: how to edit tiffs without zuking up the alpha
I tried downloading the two files to play with them. The second file 'after.tiff' is fine, but opening 'before.tiff' using the gimp gives errors - about unknown data segments. This is probably because Photoshop is using a newer(or non-standard) file format than the GIMP. The file itself was created using Photoshop version 5. I tried using GIMP version 1.1.23 to open it, what version is Dave using? Dave Morse requested all repies are CC'd to him, his address is: [EMAIL PROTECTED] __ Do You Yahoo!?

how to edit tiffs without zuking up the alpha
Hi, I've got tiffs created in Photoshop that I need to crop using Gimp. They have alpha. If I open the up in Gimp, use the crop tool, then resave, the next time I open them I discover that only the alpha-mask has been saved in place of the rgb data. before save: http://24.16.52.60/~dm/before.tif after save: http://24.16.52.60/~dm/after.tif Needless to say, this is not what I want. How do I do what I want? (Please CC me on replies, as I don't subscribe to gimp-user)
