What is the .pct file extension used for?
The .pct file extension format or PICT format was developed by Apple Macintosh in the year 1984. It was a metafile container element which recorded a series of images created using the Apple QuickDraw application. Apple QuickDraw was a 2D graphics library which was a part of the Apple Macintosh OS and was derived from the Apple’s application Lisa. The image data was represented in 2 formats:
- PICT 1 – This was the original format developed for QuickDraw which was used to create images using 8 colors. It was first released with QuickDraw version 1 and was supported on the monochrome graphics (black and white) with 72DPI as its fixed resolution.
- PICT 2 – This was a newer format released for QuickDraw version 2 which was developed for color monitors. This color format had 256 colors and was represented in a palette and supported multiple resolutions. The PICT 2 format was updated to support 24 and 32-bit colors and included support for raster and vector images.
The .pct file extension format was used to represent Bitmap which was compressed using the PackBits compression algorithm. The JPEG compression algorithm was used once the QuickTime application was included in Mac OS.
