Hey. Thanks for your time. If I have two different sized textures and I want to copy certain pixels from the low res texture to the corresponding location on the high res texture, how can I do that?

depending from your API
you can DX10 UpdateSubResource/Map functions to copy area from 1 texture to another
DX9/OGL lock and unlock ur texture copy data from it
Shader way: copy it in shader with full screen quad

for more help try specifying your API, what u wanna achieve by that, e.t.c
