- Description
- Compressed bitmap image that uses wavelet compression instead of the DCT compression used by standard .JPEG images; supports 16-bit color, alpha transparency, and lossless compression.
- 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.
