            Bug ID: 1039268
           Summary: png images not displayed
           Product: Fedora
           Version: 20
         Component: perl-Tk
          Assignee: andreas.bierfert at lowlatency.de

                CC: andreas.bierfert at lowlatency.de,
                    perl-devel at lists.fedoraproject.org
   External Bug ID: CPAN 87016



Description of problem:

png images cannot be displayed anymore using perl-Tk's Tk::PNG module. This is
probably related to https://rt.cpan.org/Public/Bug/Display.html?id=87016

The problem does not appear anymore with a development release of Perl/Tk, e.g.
SREZIC/Tk-804.031_502.tar.gz

Version-Release number of selected component (if applicable):

perl-Tk-804.031-4.fc20.i686


How reproducible:


Steps to Reproduce:
1. Try the following oneliner with a random png image: perl -MTk -MTk::PNG -e
'$mw=tkinit;$mw->Label(-image => $mw->Photo(-file => shift))->pack; MainLoop'
pngtest.png 
2.
3.

Actual results:
Error message "invalid after png_start_read_image or png_read_update_info at
/usr/lib/perl5/vendor_perl/Tk/Image.pm line 21.", no png image is displayed

Expected results:
png image should be visible in a X11 window, like it's the case with fedora 19.
