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 PaintShop 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, additional artistic tools and/or plugins. The particular bundled programs have varied with each numbered version and have not been sold by Corel as separate products. PSP comes with an interface for automating tasks with scripts written in Python. History Originally called simply Paint Shop, the first version, 1.0, was a basic picture converter between BMP, GIF and PCX formats, conceived by Robert Voit and developed by Joel DeRider. It was released by Robert Voit in August 1990. Paint Shop was originally distributed as shareware and is still available at many download sites (4.12 being a popular version). Most newer versions are only commercially available although some have been distributed in the United Kingdom in computer magazine CDs after they became obsolete. PaintShop Pro 5 added support for layers as well as CMYK and HSL colour modes, included JASC Animation Shop for creating animations and in fact was marketed as "Paint Shop Pro 5.0 with Animation Shop". PaintShop Pro X6 was the first to be available as a native 64 bit version (purchase includes both versions). PaintShop Pro X7 includes content-aware features such as "Magic Fill" and "Smart Edge" as well as support for XMP sidecar files that preserve edit settings for raw formats. From 2006 to 2011 (versions XI to X3), PaintShop Pro was marketed as "Corel Paint Shop Pro Photo". Having dropped the "Photo" part of the name in version X4, Paintshop Pro X5 was derived from Ulead Photo Explorer after Corel's acquisition of Ulead. On November 28, 2007, Corel announced that the office in Eden Prairie, Minnesota, where Paint Shop Pro was created, would be shut down, with development moving to offices in California and China.
