PaintShop Pro (
PSP) is a
raster and
vector graphics editor for
Microsoft Windows. It was originally published by
Jasc Software. In October 2004,
Corel purchased Jasc Software and the distribution rights to Paint Shop Pro. PSP functionality can be extended by
Photoshop-compatible plugins. The X-numbered editions have been sold in two versions: PaintShop Pro, which is the basic editing program, and PaintShop Pro Ultimate, which bundles in other standalone programs. The particular bundled programs have varied with each numbered version and have not been sold by Corel as separate products.
