[TYPO3-english] alpha background GIFBUILDER TYPO3 problem

[Lukas Stancik]

Hi Francisco,

IMHO it can not be achieved at all. I mean without changing the core.
The combine/composite command of ImageMagick is always called with 
"+matte" option (see t3lib/class.stdgraphic.php around line 2549) which 
disables the alpha channel of the output image.

I have tried to set it to "-matte" and "-alpha On" but without any effect :(

But trying to run this in console:
Note: image1.png contains some graphic with transparent background, 
image2.png is fully opaque

composite -compose src-over -matte image2.png image1.png output.png

behaves as intended = the resulting image is a composition of the two 
images with transparent background...

Regards,

Lukas
