Buttons
These buttons (except Transparent Background) apply when exporting 256 color images or less.
These files are created with a limited palette of colors, and these controls provide a great degree of
control over those palette colors. See Color Selector above on how to select a color, or click on a
color in the Color Palette
).
Lock a Color
You can specify the number of colors you want in the palette of exported bitmaps. You may want to
ensure that certain colors always appear in the palette; you can lock these colors. Click on a color to
select it, then select the Lock
button. A small square appears in the bottom left of the color to tell you it is a locked color.
Make a Palette Color Web Safe
When clicked this button will shift the selected color to be one of the 216 common web browser palette
colors. This is a legacy system that is no longer particularly important or relevant, as nearly all computers
can display millions of colors, and there's no benefit in restricting web graphics to only this limited
palette.
Make the Image Background Transparent
Make any areas not covered by the selected objects transparent. Selecting this option automatically
makes one entry in the palette transparent.
Make a Palette Color Transparent
Make this color entry transparent. Note the difference between this option, which makes parts of the
selected objects transparent, and Make The Image Background Transparent
which makes those areas behind the selected objects transparent.
Delete a Palette Color
Delete this color from the palette. Any areas in the bitmap that use the deleted color then use the nearest
color in the palette. The fewer colors in the palette, the smaller the bitmap file.
Restore a Previously Deleted Color
Undelete a deleted color.
Add system colors
Adds 28 colors to the palette. These colors are the regular Windows system colors and a number of
primary colors. This ensures the palette includes a spread of colors and may improve the quality of the
image, particularly if it contains a wide range of colors. You may need to experiment with this option to
get the best results.
Bitmap Size tab
