Paint Shop Pro also offers support for more than forty different graphic types (including both raster/bitmap and vector-based images) as well as support for third party Adobe compatible plug-in filters. All the popular graphic types are supported, including GIFs (with transparency and interlacing options), JPEGs (with a progressive JPEG option), Portable Network Graphics (with a PNG transparency option), Windows Bitmap (BMP), Kodak Photo-CD (PCD), Corel Draw (CDR), Microsoft Paint (MSP), and Photoshop (PSD), as well as less familiar file types like Electronic Arts (IFF), GEM Paint (IMG), Truevision (TGA), Portable Bitmap (PPM) images, and a whole lot more. In fact, Paint Shop Pro more than doubles Photoshop's support of graphic formats.
Definitely one of its best features, Paint Shop Pro's on-line help system implements tabbed folders, quick navigation, extensive documentation, and advanced search capabilities, making the task of understanding how to use the program's massive collection of features a surprisingly enjoyable experience.
