PCT to STL Conversion: FAQ

What are PCT files?

PCT is an image file format associated with Macintosh QuickDraw, a graphics program developed in the 1980s as part of the Apple Macintosh operating system. The initial version of the format, called PICT 1, could store 8 colors, while the later developed PICT 2 supported 24 and 32-bit color images. In recent years, the format has decreased in popularity, being gradually replaced by more versatile formats.
