Image Mask as Aperture Grille #29

Open ghost opened 5 years ago

ghost commented 5 years ago

Hi again,

I was wondering how feasible would it be to implement a single transparent .png image, either the exact size of the rendered screen or by tiling, over the emulation in a really crude way so that it looks somewhat ok with the bilinear filter but pixel perfect on a 1:1 screen? I don't know how much effort it would take to implement shaders like those of retroarch but I think an overlaid image is comparably easier. I'm more like an aperture grille person but this can also be used to make scanlines of any shape and color too.

What do you think?

This is possible, but quite a bit of work to make it work without slowdown. I will look into it whenever I have a lot of time.

I would also like to see some kind of scanline emulation. It can be real simple, perhaps by letting the integer scaler draw one line per scanline in half brightness, or something similar.
