This doesn't appear to have been fixed in 1.5.0. Please update if this is not correct.

The problem seems to still persist in version 1.9.5.

Is there a fix available somewhere or is someone working on this already?

Any news on this?

Will evaluate during the bughuntdays (this Friday). If I can't figure it out, I will reassign it to Alex

so Dolf any news on this or can you give a hint about the problem?

Nope, I got caught up doing other stuff. Will try to evaluate asap though.

Dolf, is there any chance this bug could get fixed soon? regards

I wanted to do this during some BHD's, so we're basically waiting for the next BHD.

Can you give as a hint in which file we should look for this bug? We can't wait for the next bhd!

I haven't dug into it myself. Feel free however to take over this issue, I just felt like resolving a couple of _pdf issues ;) I think chances are that it's somewhere in zend_pdf_color, but I'm absolutely not sure about that.

Has this been fixed, or is there any work around?

Any ideas here?

Postponing as per ralph's request. Under protest...
