Subject: Accessing GD's alphaBlending() from Imager
Hi, I think it would be nice to have the possibility of blending color with Imager. In my case, I am plotting graph with Imager::Plot and the line for the last dataset rendered cover the previous one. I would like the color to blend where line cross instead. Apparentely, recent GD have the alphaBlending function which could permit this. I swear I saw something about about accessing the gd object directly in the doc but I can't remember where. If it is possible at all, let me know !

Imager does not use GD in any form. Hence there is no access to an underlying GD object. Tony

> Sorry for the mistake. Color blending would still be nice.
You're right. I've chanaged the subject of the ticket to indicate this. It's a big change, but a useful one. The only way I can see to do this right now would be to draw to a temp image and use that as a pattern fill with the appropriate combining mode. Of course, if we enable alpha blending, we should allow all the other combining modes that the fill objects allow ;) Tony
