ATK to PIC Conversion: FAQ

What are ATK files?

ATK is a raster image file format associated with Andrew Toolkit, a set of tools for distributing documents that contain embedded objects. The format was developed as part of the Andrew Project, launched at the Carnegie Mellon University in the United States, in the early 1980s. The project resulted in the development of several other types of computing infrastructure tools too, and was considered an important step for making such tools more accessible at the time.

What are PIC files?

The PIC file format was first associated with PC Paint and later on with its developed version, Pictor Paint. It was one of the first formats accepted as a standard under the DOS platform, and it was developed by John Bridges. PIC files represent raster images, which can use an up to 24-bit color range. The advanced versions of PC Paint and Pictor Paint support image compression and the PIC files created using these programs are device-independent.
