[Bug 134313] Re: pdfimages produces inverted image for black & white image
Related: "In general, Acrobat and Reader will show a negative image when the image data indicates that it needs to be inverted. When you have images that are compressed with the CCITTG4 algorithm, there is a flag in the image data that indicates if a logical "1" indicates black or white. The software that created this document must have used the wrong value for this flag. I've seen similar effects also with certain CMYK JPEG images (but it's been years since I encountered the last one of those) where the PDF generator created corrupt data."

[Bug 134313] Re: pdfimages produces inverted image for black white image
Hello Greg, Thanks for looking into this issue. No, everything works now fine with the pdfimages program on uptodate Hardy. I had added poppler because the package poppler-utils, is the one hosting the pdfimages command on a vanilla Ubuntu system, so it is no longer an issue with poppler as well : I have just tested on a system with poppler-utils installed. I confirm the bug is still there on uptodate Hardy with the GIMP.

This behavior can be reproduced with the GIMP : - Open the attached file test.gif in the GIMP : - Save it as test.pbm, choosing raw data formatting. - Close the image window - Open the previously saved file test.pbm - The image is inverted I confirm the behavior with pdfimages included in package poppler-utils All of this is tested on an up to date Gutsy as of 2nd of October 2007 gimp 2.4.0~rc1-3ubuntu2 poppler-utils 0.6-0ubuntu1 gimp and poppler-utils should be added to the list of affected packages. ** Attachment added: File to be opened in the GIMP for testing http://launchpadlibrarian.net/9669657/test.gif ** Also affects: gimp (Ubuntu) Importance: Undecided Status: New -- pdfimages produces inverted image for black white image https://bugs.launchpad.net/bugs/134313 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug contact for gimp in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
