Hi All,

I've been messing around with blend, trying to create glow effects.

I'm drawing an ellipse to a PGraphics buffer and using .filter() to blur it.

This is all fine, but when it comes to rendering the buffer and using translate to position it, image() works fine and renders to the correct position but blend() ignores the translation.

eg.
Code:

translate(50,50);
//below in correct postition
image(pg,0,0);
//below in wrong position
blend(pg,0,0,w,h,0,0,w,h,ADD);
//below in correct position
blend(pg,0,0,w,h,50,50,w,h,ADD);
 

Anyone have any advice on this?

Thanks in advance,

David
