A GIF with a transparent background (the airplane) is displayed over a blue
background image.
In Corel Painter, the method of defining transparency during GIF export is to define
the transparent areas based on the content of the selected layers. The edges of the
floating elements on the layers help define the transparent areas. For more information,
see “Layers” on page 479.
When saving to the GIF file format, you can reduce the number of colors, which
translates into smaller files.
To create a transparent GIF from a layer or group of layers
1 From the Layers panel, select a layer or group of layers.
To output transparency in a GIF, you need an active selection.
2 Choose Select Select Layer Content.
3 Choose File Save As.
4 Choose GIF from the Save As Type list box.
5 Specify a location and filename, and click Save.
6 In the Save As GIF options dialog box, enable the Output Transparency check
box to make the selected area the only part of the canvas displayed on your web
page.
7 Enable one of the following options:
• Background is WWW gray — sets the transparent color to 75% gray
• Background is BG color — sets the transparent color using the additional
color specified in the Colors panel. Note that this setting does not refer to the
HTML page’s background color.
