Transparent areas are designated
with a grid.
If necessary, drag in the Preview

8 Choose one of the following
imaging methods:
• 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 colors chosen to
generate a more accurate, less
banded result. Unfortunately,
Dither Colors can reduce the
effectiveness of GIF file com-
pression.
Note
•
The RIFF format contains data about
your image that is lost when you convert it
to GIF or JPEG. If you want to edit the
file later, save a RIFF copy before saving to
the GIF or JPEG file format.
Creating Animated GIFs
Corel Painter can open a QuickTime
movie, which can be painted on, then
saved as an animated GIF.
Additionally, you can create a new
movie or animation from scratch in
Corel Painter and save it as an
animated GIF, QuickTime, or Audio/
Video Interleaved (AVI) movie.
For information about creating
movies, refer to “Creating a Movie” on
page 425. For information about
creating and exporting animated
GIFs, refer to “Animations for the
World Wide Web” on page 442.
Reducing the Number of
Colors
Web designers are always seeking a
careful balance when creating
graphics for the Web. Artwork and
imagery must be as rich and vibrant as
possible while remaining small and
easily downloadable.
One way of keeping an image’s file
size small is to reduce the number of
colors used to create that graphic
element. Reducing the number of
colors used reduces file size and,
therefore, download time.
A Web artist may end up saving
multiple versions (varying in the
number of colors used) of the same
graphic element. These versions must
then be placed on a page, loaded to the
page, and viewed to determine if the
quantity of colors used is acceptable.
This whole process can be time-
consuming and confusing.
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 GIF Save As
dialog.
To visually reduce the number of
colors
1 Choose File menu > Save As and
name your image file.
2 Choose the GIF file format, and
click Save.
3 Click OK to dismiss the layer
warning, if displayed.
4 In the Save As GIF Options dialog
box, in the Number of Colors area,
choose 256 colors.
