SUL to PNG Conversion: FAQ

What are SUL files?

SUL is an old and obsolete image format file associated with GFA RayTrace — a program designed for Atari ST computers. The software was released in the late 1980s and allowed users to operate with 3D objects in an incipient stage, usually implying a lot of time for required calculations. SUL files are now considered rare, so opening them probably requires conversion.

What are PNG files?

The PNG (Portable Network Graphics) file format was designed in the mid-1990s as an improved alternative to the previously existing JPG and GIF formats, and as an extension which would be particularly web-friendly. In time, PNG files have gained a wide popularity and are highly appreciated at the moment for their ability to provide a lossless compression of images, which translates in high-quality and detailed renderings.
