Good to see you again - where have you been the last year or two?DaveC said:Yes and when you letterbox the sides you have to scale fractionally both directions by doubling some pixels, and not others as 220 doesn't go into 272 evenly. Then you put a *filter* over that to blend it together. When you do that you lose sharpness and contrast, that is a fact.
No, you don't "double some pixels", you completely redraw the image, with each pixel created from a combination of nearby pixels in the source image. The "filter" is what determines which source pixels are selected, e.g. Gaussian blur. This process, if done correctly, will not result in a significant drop in visual quality, as I'm sure people who watch movies and upscaled games on their PSP/DSs can attest.
