Image stored in the Macintosh PICT format, which was developed by Apple in 1984 for storing images using Apple QuickDraw technology; contains image data in one of two formats, PICT 1, the original format that stores 8 colors, or PICT 2, a newer format that allows thousands of colors (24 and 32-bit images); supports both raster and vector images. While PICT images most commonly use the .PICT file extension on Macintosh computers, they typically are seen with a ".pct" extension in Windows. The PICT format has largely been deprecated to the more flexible .PDF format in Mac OS X.
