Subject: Accessing GD's alphaBlending() from Imager
Download (untitled) / with headers
text/plain 493b
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

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
