Graphics / Appropriate way to do get/set render buffer directly

« on: February 08, 2016, 06:29:01 am »

Hello

I use sfml to make some 2d game (400x300 px) and finding the way to do image scale up & filter to 800x600.
I have scale up module API and algorithm already.
Just want to know a good way to get render buffer to be input of scale up/filter module.
And how to set the output scaled buffer back to draw on screen.

Thanks
