SCALERS : 2XPM
|Reported by:||SF/gustavejr||Owned by:|
2XPM, based on the Scale2X idea, analyzes any pixel relation with its eight neighbouring pixels, to guess some diagonal lines and rounded edges and apply the obtained information in the four resulting pixels.
There are two versions of this scaler, HQ and LQ.
HQ is the "full-featured" version, its main purpose is to enhance image quality, withouth worrying about CPU usage. It uses different levels of alpha-blending to enhance image quality when necessary.
LQ is the low-quality version, which detects most of the lines detected in HQ, making it faster but the resulting image will be more pixelated. Also, alpha-blends are limited to 50% only, which is optimized. LQ aims for speed, HQ aims for image quality.
The programmer of this scaler says that it's a work-in-progress and unfortunately he hasn't developed a 16 bit version of the scaler, I am sure you guys can work around with it.
