Description of problem: Strange hieroglyphics instead of "hello" text appearing in image. Version-Release number of selected component (if applicable): netpbm-10.47.13-1.fc12.x86_64 netpbm-devel-10.47.13-1.fc12.x86_64 netpbm-progs-10.47.13-1.fc12.x86_64 How reproducible: Always Steps to Reproduce: 1. ppmlabel -x 50 -y 100 -text 'hello' bit3.ppm >! a.ppm 2. display a.ppm 3. Actual results: See attached image Expected results: Additional info: Problem also appears to occur on F11 system too.

This is a show stopper for me, since software that I developed under FC9 makes heavy use of ppmlabel. Is there a work-around? SOMETHING? This works correctly in the netpbm implementation running under MacOS, but I'd really like it to work here.
Could you please attach the bit3.ppm to this bug to let me reproduce or, alternatively, could you provide an easier reproduce case?

Created attachment 441252 [details] After I executed ppm label command OK, here's the same ppm file after I issue the command: ppmlabel -x 50 -y 100 -text 'hello' before.ppm > after.ppm Note the Druidic runes above and to the left of the eye's pupil (in red).
Do we have a workaround for this?
I've got the obvious work-around: I went back to a release I know worked (FC10), and grabbed, the FC10, FC11, FC12 and FC13 src.rpm files. I built static versions of each and discovered that the problem occurred between FC11 (netpbm-10.35.62) and FC12 (netpbm-10.47.04), which is not surprising considering the quantity of changes between those two releases. My work-around is there to use the fc11 version (calling it something else). Since it is statically built (at least for netpbm), my new (old) version won't interfere with anything else on the system. I believe the bug was introduced in lib/libppmd.c. The diff between the 10.35.62 and the 10.47.04 version of that file is 1414 lines long! Most of the changes have to do with variable name changes (e.g. "cx0 became c0.x, which is to say that the concept of "c0" became a struct rather than just a bunch of variables.) In any case, someone with the ability to build all of the interim versions and test each one will probably be able to narrow it down to a smaller number of changed lines). At least for right now, since I have a work-around, I should be working on other things, but I'm happy to help time permitting. Diff between 10.35.62 and 10.47.04 versions of lib/libppmd.c attached.

This message is a reminder that Fedora 12 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 12. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '12'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 12's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 12 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
This is still a problem with FC13. It basically makes the ppmlabel command useless and large parts of the ppmdraw command are also useless. I am surprised there isn't some kind of regression test against this package!
It works for me with netpbm-10.47.17 on F14 so it seems the problem is only in the old netpbm-10.47.13 in F13. I will release updates to address this soon. Thanks for the feedback!
