Importing and Exporting 615

If you choose 256 colors of less, you have the option to use simple transparency (Wine
glass icon-see below). This doesn't support semi-transparent pixels, only "on/off" fully
opaque or fully transparency pixels, and so can produce jagged edges.

Max Colors
If you select a Color Depth of 256 or less you can control exactly how many colors are
used in the file. This provides a high degree of control over quality vs. file size. Just enter
the required number of colors and press the PREVIEW button to preview.
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.
