In the image to be superimposed (indexed color is assumed), a given palette entry plays the role of the transparent color. Usually the index number 0, but other may be chosen if the overlay is performed by software. At design time, the transparent color palette entry is assigned to an arbitrary (usually distinctive) color. I have a device that supports 4-color graphics (much like CGA in the old days). I wanted to use PIL to read the image and convert it using my 4-color palette (of red, green, yellow, black), but I.

I remember in GIMP 2.4 editing palette in an indexed image was as easy as changing the foreground color but I'm a little lost in GIMP 2.8 as there is no Dialog menu. So, I played around a little and found out it was in the colors Map Set color map hit Default scroll to the top right click the image palette and bring up the palette. You only need to upload an image, we can get the main color in the image and automatically generate a color palette. This tool can extract the most important colors according to the complex color of the picture. Simple pictures may only extract 1-2 kinds, and many kinds of color pictures will extract 5-10 colors.

Figure 15.16. An indexed image with 6 colors and its Colormap dialog
The Colormap (Indexed Palette is a better name) dialog allows you to edit the colormap of an indexed image. (If the mode of the active image is RGB or Grayscale instead of Indexed, the dialog is empty and unusable.) This is a dockable dialog; see the section on Dialogs and Docking for help on manipulating it.
The “Colormap” dialog is a dockable dialog; see the section Section 2.3, “Dialogs and Docking” for help on manipulating it.
You can access it:
- from the image menu: Windows → Dockable Dialogs → Colormap;
- from the Tab menu in any dockable dialog by clicking on and selecting Add Tab → Colormap.
In the Windows menu, there is a list of detached windows which exists only if at least one dialog remains open. In this case, you can raise the “Colormap” dialog from the image-menu: Windows → Colormap.
In an Indexed image, instead of being assigned a color directly (as happens in RGB and Grayscale images), colors are assigned to pixels by an indirect method, using a look-up table called a colormap.
To determine the color that should be shown for that pixel, GIMP looks up the index in the image's colormap. Each indexed image has its own private colormap. In GIMP, the maximum number of entries in a colormap is 256. For a maximum-sized colormap, each index from 0 to 255 is assigned an arbitrary RGB color. There are no rules restricting the colors that can be assigned to an index or the order they appear in: any index can be assigned any color.
It is important to realize that the colors in the colormap are the only colors available Houdahgeo 4 3 1 download free. for an indexed image (that is, unless you add new colors to the colormap). This has a major effect on many GIMP operations: for example, in a pattern fill, GIMP will usually not be able to find exactly the right colors in the colormap, so it will approximate them by using the nearest color available. This is sometimes referred to as Quantization. If the colormap is too limited or poorly chosen, this can easily produce very poor image quality.
The Colormap dialog allows you to alter the colormap for an image, either by creating new entries, or by changing the colors for the existing entries. If you change the color associated with a given index, you will see the changes reflected throughout the image, as a color shift for all pixels that are assigned that index. The entries are numbered with 0 in the upper left corner, 1 to its right, etc.
Here are the operations you can perform using this dialog:
This sets GIMP's foreground color to the color you click on, as shown in the Toolbox color area. As a result, this color will be used for the next painting operation you do.
This sets GIMP's background color to the color you Ctrl-click on, as shown in the Toolbox color area.
This sets GIMP's foreground color to the color you click on, and also brings up a Color Editor that allows you to change that colormap entry to a new color.
You can select a different colormap entry by typing its index here, or clicking the spinbutton to the right.
This area shows a hex-code representation (such as is used in HTML) for the color assigned to the currently selected colormap entry. You can edit the color here, instead of using a Color Editor, if you want to. See HTML notation
This button (in the lower left corner of the dialog) brings up a Color Editor that allows you to change the color for the currently selected colormap entry. The effect is similar to double-clicking on the entry, except that it does not set GIMP's foreground color.
Pick Color Palette From Image
This button (in the lower right corner of the dialog) allows you to add new colors to the colormap. If you click on the button, the current foreground color, as shown in the Toolbox, will be tacked on to the end of the colormap. If instead you hold down Ctrl and click, the background color from the Toolbox will be added. (If the colormap contains 256 entries, it is full, and trying to add more will have no effect.)

If you make a mistake, you can undo it by focusing the pointer in the image whose colormap you have changed, and then pressing Ctrl+Z or choosing Edit → Undo in the image menu. |

This dialog provides the most commonly used methods for altering the colormap for an indexed image. The color tools, such as Brightness/Contrast, Hue/Saturation, etc, do not operate on indexed images. There are a few plug-ins that do so, including the “Normalize”, “VColor Enhance”, and “Stretch Contrast” operations, and it is possible to create others as well. |
Note |
---|
If you paint an indexed image with a color which is not in the Colormap, GIMP will use the most similar color of the Colormap. |
Right-clicking on a color in the Colormap selects this color and opens a pop-up submenu:

This command opens a color selector which allows you to modify the color.
This command is enabled only if the indexed palette contains less than 256 colors. The background color of the Toolbox is appended to the color map.
