Description

$TYPO3_CONF_VARS['GFX']['png_truecolor'] needs to be enabled for transparentBackground property of GIFBUILDER objects to work.

Before 4.0 in t3lib_stdGraphic::output, IMreduceColors was only called when reduceColors was enabled.
Since 4.0 it is also called if png_truecolor is disabled and if it is a truecolor image. The latter condition was dropped in 4.4.
I guess that moment GIF transparency stopped working because in 4.2 it was still working.

This is related to #14537 with whose fix the unconditional IMreduceColors call was added and to #14537 where Marius Muehlberger struggles with this problem.

Hi,

as this issue is very old. Does the problem still exists within newer versions of TYPO3 CMS (6.1.7)?
