Class used to export maps to GIF (Graphics Interchange Format).
Use the ISupportErrorInfo method InterfaceSupportsErrorInfo to determine if the object supports extended error information. If the object supports extended error info, VC++ developers should use the OLE/COM IErrorInfo interface to access the ErrorInfo object. Visual Basic developers should use the global error object Err to retrieve this extended error information.

Use the ExportGIF CoClass to export your map to GIF (Graphics Interchange Format) format. GIF files are a standard raster format for use on the Web. GIFs cannot contain more than 256 colors (8 bits per pixel), which makes them smaller than other file formats. They are a good choice for maps that contain a limited number of colors, but may not display raster data correctly due to the color limitation. GIF files also have the ability to define a transparent color. This allows part of the image to display as transparent in a web browser, allowing backgrounds images or colors to show through.
