public bool PickSamePalette { get; set; }
Value that indicates whether to generate a unique global palette for all GIF frames or generate a separate palette for each frame. Possible values are:
Value | Description |
---|---|
true | Generate a unique global palette for all GIF Frames. |
false | Generate an individual palette for each GIF Frame. |
This example will optimize a Gif image file and then save it to a separate folder
