https://bugzilla.novell.com/show_bug.cgi?id=882456 https://bugzilla.novell.com/show_bug.cgi?id=882456#c0 Summary: Image Magick display will not show image through pipe Classification: openSUSE Product: openSUSE 13.1 Version: Final Platform: x86-64 OS/Version: openSUSE 13.1 Status: NEW Severity: Normal Priority: P5 - None Component: Other AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: david.westfall@red-inc.us QAContact: qa-bugs@suse.de Found By: --- Blocker: --- User-Agent: Opera/9.80 (X11; Linux x86_64) Presto/2.12.388 Version/12.16 I have a perl script that draws a test pattern using GD and pipes it to display. This works in 12.2 and before, I do not have any 12.3 to test. It does not work in 13.1. To find the problem I sent the output from perl to a files then display was able to open the file. bin/TestPattern.V2.0.pl --raw-output>junk.png;display junk.png To test if the problem was in perl or with display I use the following command. cat junk.png|display This command works in 12.2 but fails in 13.1. The problem is with any png not just waht was created by my perl script. Dave W Reproducible: Always Steps to Reproduce: 1. Normal: Run bin/TestPattern.V2.0.pl 2. Command line pipe bin/TestPattern.V2.0.pl --raw-output|display 3. Work around bin/TestPattern.V2.0.pl --raw-output>junk.png;display junk.png 4. Any PNG: cat image.png|display Actual Results: display: no decode delegate for this image format `/tmp/magick-7619a7kj6Q1HIKoE' @ error/constitute.c/ReadImage/552. Expected Results: Image is displayed. This is how my perl script either pipes to display or does raw out put. if ($RawOutput eq "No") { $png_data = $img->png; open (DISPLAY,"| display -geometry ".$DeskTopWidth."x".$DeskTopHight."+0+0") || die; binmode DISPLAY; print DISPLAY $png_data; close DISPLAY; } else { print $img->png; } -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
