Making a palette color transparent

Paletted images (those with 256 or fewer colors) do not support

transparent backgrounds, but you often need a way to make part of

your image transparent when you are using an image on a Web page.

For example, you may have a round logo and you want the

background of the Web page to display around the logo.

Most Web browsers can choose not to display one color, effectively

making it transparent. In Corel PaintShop Pro, you have two ways to

make a color transparent:

• You can make one color in an image palette transparent. The color

can be the background color or any color from the image. To set a

transparent color, the image must have only one layer and use an

image palette, which means the image must have a color depth

less than 16 million colors (24-bit).

• You can edit a 16 million-color image, save it to the PspImage file

format, then use the GIF or PNG optimizer to export a copy of the

image. With these optimizers you can set the transparency of the

image. This is recommended because it does not change the color

depth or flatten the layers of your original PspImage file. For more

information saving optimized images, see “Saving images for the

Web” on page 757.
