I want to make the picture Indexed color.
With Photoshop, we can do like this.


But how do we do in ImageEN ?

Hi

It is not possible with v6.2.2, but we have an update that supports it. Email me to download it.


  // "Web Safe" Palette (actually this is a 216 colors palette + 32 levels of gray from 216 to 248 + 7 color rainbow from 249 to 255, which are often used together as the web-safe palette)
  WEB_SAFE_PALETTE : array [0..255] of TRGB = ( (B: 0; G: 0; R:0), (B: 51; G: 0; R:0), (B: 102; G: 0; R:0),
