[TYPO3-english] GIFBUILDER and blending

[Christian Hennecke]

Hello,

I would like to blend two images using the "Multiply" effect. Both 
GraphicsMagick and ImageMagick support this (e.g., via "gm composite 
-compose Multiply"), but GIFBUILDER does not seem to support this. In 
fact, the "TypoScript by Example" documentation states that it does not,
but this is several years old.

Does anybody know how to still achieve the effect? I tried using the 
SCALE object with the params option but that does not work as it only 
work on a single image using "convert" instead of "composite".
