Web : Reducing the number of colors in GIF files
Quick links to procedures on this page:
Web designers are always seeking a careful balance when creating graphics for the web. Artwork and images must be as rich and vibrant as possible while remaining small and easily downloadable.
One way of keeping the file size small is to reduce the number of colors used to create the image. Reducing the number of colors reduces file size and, therefore, download time.
A web artist may end up saving multiple versions of the same graphic element, varying the number of colors used. These versions must then be placed on a web page to determine if the quantity of colors used is acceptable. This whole process can be time-consuming.
In Corel Painter, you can make this decision during the process of saving the image to GIF format, by using the Preview window on the Save As GIF Options dialog box.

Quantize to Nearest Color — causes Corel Painter to look at each pixel and pick the nearest color. This is useful when the image you are saving has broad areas of a single color. |
|

Dither Colors — causes Corel Painter to apply a stippled effect to the chosen colors to generate a more accurate, less banded result. |
The RIFF format contains data about your image that is lost when you convert it to GIF. If you want to edit the file later, save a RIFF copy before you generate a GIF version.
