Description
A PCT file is an image saved in the Macintosh PICT format, which was developed by Apple in 1984 for storing images using Apple QuickDraw technology. It 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). PCT files support both raster and vector images.
Image file format related to the .PNG format, but uses lossy compression like standard .JPG files; developed as a sub-format for .MNG objects, but can also be used as a standalone raster image format.
