[Typo3] how can i generate transparent PNG-files with partial transparency?

[Hendrik Stey]

hello,


dear jan, thx for your answer but of course joey is right.

a quite good and simple explanation of the difference of index
transparency and alpha transparency (alpha
transparency is what i need) can be found here:

this must be f***in' possible - i won't give up yet.

thx and bye

hendrik.
