Come together with the global Drupal community in Rotterdam, 28 Sept – 1 Oct 2026. Sessions, contribution, connection, and Early Bird savings until 8 June.I really enjoy using the image_cache and image_cache_actions modules.
But what i just cant seem to get working is to set the actual transparency of the png in a layer.
So far it just blends colors instead of letting me see the sites (or whatever) background.
Using imagecache to write pictures into other folders for usage outside Drupal; i tried googling the GD2 documentation and forums so i could add a custom action.
But im just to stupid to understand the imagecache ap.
thanks in advance to whoever can help me further on this.

dman commentedWherever possible, I've tried to support transparency through the processes.
If you use a transparent input, and pass some actions over it, it should produce a transparent output.
If your input is not transparent, it can be ghosted out using the alpha action.
You'll have to describe an example of your preset for more info. There may be a few actions (like scaling) that somehow destroy transparency.

dman commentedany more detail? transparency is supposed to work, but there may be some order of actions where it gets lost. Specifically some of the (original imagecache actions) do a image copy rather than a transform, and this loses an alpha setting in the process.
