Custom Color Depth Effect Options Description Table
Note: This task page can also accessed from the Capture Preview window or SnagIt Editor by choosing Colors > Color Depth.
You get the best possible image quality by using a unique, Optimized palette. To make sure a bitmap has a unique palette, open an image from a file that is 8 bits per pixel (256 colors) or fewer. This file contains a unique palette for the image. By default, SnagIt loads the palette that is stored in the file and relates it to the bitmap in memory. Or let SnagIt make an optimized palette for the image by decreasing a 24-bit image (16 million colors) to 8 bits per pixel (256 colors). Images with optimized palettes may exhibit some palette shift.
The following table describes each of the Custom Color Depth options along with its use.

(This option will be available only if Colors is set to 256 or fewer colors.)

Palette
(This option will be available only if Colors is set to 256 or fewer colors.)
|
Four Palette options are available:
- Fixed
Saves the image using a fixed palette. The advantage to using a fixed palette is that it prevents a decrease in the quality of image appearance when more than one image is open.
- Optimized
(Recommended) saves the image using a palette optimized for this image. In general, use an Optimized palette if the image is to be viewed by itself.
- Identity
Saves the image using the Windows system palette. Use this selection if the image contains Windows screen colors.
- Netscape Fixed
Saves the image using the palette used by Netscape Navigator and Microsoft Internet Explorer.
Select the desired palette from the Palette list box.
