Macro Definition Documentation

HISTN

#define HISTN   (1 << 11)

color transfer somewhat based on the glorious paper ‘color transfer between images’ by erik reinhard, michael ashikhmin, bruce gooch, and peter shirley, 2001. chosen because it officially cites the playboy.

workflow:

• open the target image, press acquire button
• right click store as preset
• open image you want to transfer the color to
• right click and apply the preset

MAXN

#define MAXN   5
