stbiscalenx's Introduction

stbiscalenx

Stb Image Scale Near X. This algorithm is based on the scale2x pixel graphics algorithm. In this algorithm, “equals” is replaced by “near”, which allows it to work with full-color graphics. The algorithm remained simple, like Scale2x. This implementation can enlarge the image by 2 and 3 times.
