Edit Color Palette
Every GIF image file contains within it a color palette that defines the number of colors an image contains and the colors each index represents. The maximum number of colors that can be used in a frame is 256.
There are two kinds of palettes: Global and Local.
A Global Palette is used by all those frames in the GIF which do not have a Local Palette associated with them. The scope of the Global Palette is the entire GIF. A Local Palette is limited to a single frame. A Local Palette supersedes a Global Palette. Both types of color palettes are optional, making it possible for a GIF to contain numerous frames without a color palette at all.
To view/edit the Global Palette of the animation, select the Animation -> Global Palette... menu item. Please note, this menu item may be disabled if the animation doesn't contain Global Palette.
To view/edit the Local Palette of the selected frame, select the Frame -> Local Palette... menu item. Please note, this menu item may be disabled if the selected frame doesn't contain Local Palette. |
