[Typo3] GIFBUILDER quality issue (jpg with rendered text on it)

Hi Rafael:

Assuming you have GD > 2.0 and PHP compiled accordingly, you still need to
extend your typo3 installation, as typo3 don't use the imagecreatetruecolor
function but just imagecreate.

The easiest way to do it, in my opinion, without messing the core code, is
to extend the tslib_cObj class and modify its getImgResource function, using

$TYPO3_CONF_VARS["FE"]["XCLASS"]["tslib/class.tslib_content.php"] =

method, allowing it to handle your own image rendering code.

Right now, this function has a SWITCH construct that allows default and
GIFBUILDER. Put a third option to handle your own option, where you can then
include your own php image rendering code with true colors handling.

This is the method I chose until the core code is upgraded to handle true

Hope this helps, best regards,

Hi folx

finally I'm asking again, because, I only found obselete answers 
concerning this topic.


JPG Images combined with Text results in a 256 color gif,... 
back-converted to jpg, but this is not useful at all.
What to do? Does anybody know, if this will be fixed? Or Is there 
already a solution?

I tried it with:

typo3 version 3.7.0
typo3 version 3.8.0-dev

both versions:
imagemagick 4.2.9 and imagemagick 6.0.6

Thanx a lot in advance for an answer
