Convert PCT to SR

The PCT (Personalized Image Capture Technology) file extension, developed by Apple in 1984, is a graphics file format used primarily for exchanging images between Macintosh applications. It supports both vector and bitmap graphics and was the native format for the QuickDraw graphics library. Over time, PCT has been largely replaced by PDF, but it remains supported by some applications for legacy purposes.

The Sun Raster (SR) file extension, is a raster graphics file format developed by Sun Microsystems for use on their SunOS operating system. This format, which stores black-and-white, grayscale, and color bitmapped data, was widely used in UNIX-based systems and supported by various imaging applications. The Sun Raster format includes a header, an optional color map, and the bitmapped image data. Although it does not support transparency, it remains a simple and widely distributed bitmap format.
