About PCT (.PCT)
PCT files are image files used primarily by the Macintosh QuickDraw graphics system. They store bitmap or vector images and were common in early Mac OS environments. Interestingly, the PCT format is an extension of the PICT file format, which was widely used before modern image formats became standard.
Technical Details
A PCT file encodes image data using a combination of vector drawing commands and bitmap pixel data, often compressed to reduce file size. The format supports multiple color depths and resolutions, tailored for QuickDraw rendering. Its structure includes headers that specify image dimensions, color information, and drawing instructions, reflecting its dual nature as both vector and raster.
Additional Information & Use Cases
PCT files can contain both detailed graphics and simple bitmap images, making them versatile for early digital art and desktop publishing. Although largely replaced by formats like PNG and JPEG, some legacy applications and printers still recognize PCT images. The format helped Macintosh users create rich visual content when color displays were less common.
