The WPG format was developed by WordPerfect for use with its software products. WPG can store Vector Formats and Bitmap data.
Technical stuff
The WordPerfect (WPG) format can contain vectored or raster images.
Note: PostScript information is lost in Encapsulated PostScript images embedded in WordPerfect Graphics files. WordPerfect Graphics files with large embedded bitmaps may not appear properly on computers that use the Mach series video drivers from ATI. If you think you have this problem, try running Windows Setup and changing your video driver to the 8514/a drivers supplied with Windows.
