Use the Paint Shop Pro GIF Optimizer feature to save GIF files that maximize quality while minimizing file size. You can save images with or without transparency, depending on how you want to display them on your Web pages.
Paletted images (those with 256 or fewer colors, such as GIF or PNG files) do not support transparent backgrounds, but you often need to make part of your image transparent when displayed 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 that color transparent. Use the GIF optimizer to choose the color to make transparent.
To optimize and save a GIF file:
Choose File > Export > GIF Optimizer to open the GIF Optimizer dialog. The preview windows show the current image on the left and the resulting GIF file on the right.
Do one of the following:
Configure the settings on the Transparency, Partial Transparency, Colors, and Format tabs. For more information, see Choosing GIF Optimizer Settings.
Click the Use Wizard button to let Paint Shop Pro guide you through the process. For more information see, Using the GIF Wizard.
