Converting B_W to CG4

The B_W image format is associated with Image Lab, a software pack that provides several features for capturing and processing images. A B_W file contains a black-and-white image created with this software and is currently considered a rare format, compatible with only a limited number of image handling programs.

CG4 is a raster format associated with CALS (Continuous Acquisition and Life-Cycle Support) — a program initiated by the US Department of Defense to capture and link military data. CG4 is compatible with a very limited number of digital graphics programs. Files with this extension contain a bitmap that often uses the CCITT4 compression, which is an old fax machine standard used for black-and-white images.

So, how to change B_W into CG4?

The quick and simple way to handle your files is to get a quality piece of software, such as reaConverter.
