Description

Currently, GIFGUILDER does not support blend-modes other than "over" (gm composite -compose over) for overlaying images. Having modes like "Multiply", "Difference", "Bumpmap", etc. available would greatly enhance the image processing abilities.

As this report is very old, is the handling in newer TYPO3 CMS Versions (like 6.0/6.1) more like you expect it?

As far as I can tell from checking the latest TSref, this particular aspect has not changed since then.

Which GIFBUILDER property would that affect?

I think this would need to be set on the respective IMAGE objects.

OK, and which properties of the IMAGE object? Or: How do you set blend-mode "over"? Concerning the structure of TypoScript properties I think the other blend modes should work similarly then?!

The blend-mode "over" is currently hard-coded in class.t3lib_stdgraphic.php (at least in TYPO3 4.7, don't know about 6.x). See the function combineExec(). What we need is a new parameter "blendMode" for the IMAGE object that is then used to generate a suitable GraphicsMagick command.

The file is GraphicalFunctions.php in 6.x.

However, GraphicalFunctions.php is only the place, where it is hardcoded one time, but when you need the option for the IMAGE object, then you should edit the PHP file, which defines the IMAGE object, add a new option there and remove the hardcoded parameter from combineExec() (as otherwise you would get a command with two blend modes).

Hey Christian,

I'd really like to tackle this issue, but I'd love to have more information on how you really want your TypoScript to be written in order to make this happen.

Thanks in advance.
