Adobe Photoshop is a bitmap graphics editor (with some text and vector graphics capabilities) developed and published by Adobe Systems. It is the market leader for commercial bitmap image manipulation. It is usually referred to simply as "Photoshop". As with most of Adobe's other applications, Photoshop is available for Mac OS and Microsoft Windows; versions up to Photoshop 7 can also be used with operating systems such as Linux using software such as CrossOver Office.
