Resizing PNG files causes multiple coloration errors.
Hi,
I've been experiencing a strange problem with my Piwigo gallery for a long time. Whenever Piwigo resizes certain PNG files, their contrast is altered in a terrible way. It can be seen very clearly through multiple examples:
From the album http://jb2448.info/index.php?/category/2237
Original: http://jb2448.info/galleries/Pokemon_Sp … 04_005.png
Resize: http://jb2448.info/_data/i/galleries/Po … 005-xl.png
From the album http://jb2448.info/index.php?/category/2221
Original: http://jb2448.info/galleries/Pokemon_Sp … 01_011.png
Resize: http://jb2448.info/_data/i/galleries/Po … 011-me.png
More examples can be provided if necessary. What can I do to correct this situation? Is it a Piwigo-wide bug, or simply a bug on my installation of it?
Piwigo version: 2.8.6
PHP version: 5.2.17
MySQL version: 5.6.32-78.1-log
Piwigo URL: http://jb2448.info/
