Two versions of the WordPerfect Graphic format exist:
- WPG1, used by WPDOS 5.1, WPWin 5.x, DrawPerfect, and other products from the same period (WPG1 graphics can be imported into all later versions of WordPerfect, not only in 5.1).
- WPG2, used by WPDOS 6.x, WPWin 6.x, and all later WP versions, and by Corel Presentations and similar programs (WPG2 must be converted into WPG1 in order to be used in WPDOS 5.1).
Both these formats can incorporate vector (scalable) and raster (bitmap) graphic data. Vector graphics retain their quality when scaled up or down (like a scalable font); raster graphics lose quality when scaled up (and usually, but not always, when scaled down), and look their best only at the scale for which they were designed.
