SI to PCX Conversion: FAQ

What are SI files?

The SI format is associated with Softimage, a program first released in 1988 for Silicon Graphics workstations. The software specialized in creating 3D animation for the film, broadcasting, gaming and advertising industries, and by 2000 it was replaced by an upgraded version called Softimage XSI. SI images are currently considered rare and obsolete.

What are PCX files?

The PCX (Personal Computer Exchange) image file format is associated with PC Paintbrush, an image editing software initially designed for MS-DOS by ZSoft Corporation. At first, PCX files stored a limited range of colors but in time their range was extended to a 24-bit (true color) palette, and PC Paintbrush was adapted for Windows too. Though widely popular during the days of MS-DOS, the PCX format in time lost its appeal and was gradually replaced by formats such as JPEG and PNG.
