Looking for some general help about drawing Images efficiently and possibly using openGL

[fabien]

It seems OpenGL use may greatly help, there was a similar question (but not about svg) here:

Looking for advice on optimized image rendering, taking cache into account

I have an app that copies an image into a larger image, doing a tiling of it, and I wonder if there is a way to optimize that with cache in mind. The number of vertical/horizontal images can vary, so the final output may be arbitrarily large. My initial thought is that I want to copy the first row of source pixels into the first row of destination pixels, and repeat for the number of horizontal tiles, then the second row, etc, and repeat once I get to the next vertical tile. But I also wonder if…

But maybe just caching your svg rendered bitmap and reusing the cache might suffice, don’t know yet how it works there but I could have a look if you’re really stuck.
