Custom Color Depth
The Color Depth options allow you to customize the color depth, dithering, and palette features of an image capture.
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.
Select the Filters button. From the fly-out menu, select Custom Color Depth.
A Color Depth task page will open allowing you to customize the filter.
Use the preview image to see the effect of the filter. When the filter is set correctly, select OK.
Continue with Custom Color Depth Filter (Image & Printer Capture).

The following table describes each of the Custom Color Depth options along with its use.
Option Description & Use
Colors The options available range from Monochrome (1-bit) to True Color (32-bit).
Select the desired image resolution from the Colors list box.
Color Order
(This option is only available with 16-bit or higher color, and only from the Preview Window or Editor)
This option allows you to specify the Color Order: Red-Green-Blue or Blue-Green-Red.
Select the desired image resolution from the Color Order list box.
Dither Method
(This option will be available only if Colors is set to 256 or fewer colors.)
Use the Dither Method list box options to make the image look smoother when an image’s color resolution is decreased.

Select the desired image resolution from the Dither Method list box.
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.
OK Select OK to save changes and exit out to the previous task page, dialog box, or main SnagIt interface.
Cancel Select Cancel to exit to the previous task page, dialog box, or main SnagIt interface without saving changes.
