BMP to CG4 Conversion: FAQ

What are BMP files?

The BMP or Bitmap file format is a popular raster graphic format, compatible with a wide array of image processing software, both on PC and Mac computers. BMP files store grids of pixels and detailed information concerning color tones and shades, and are highly appreciated for their ability to provide increased quality images. However, due to the lack of any compression algorithm in storing pixel data, BMP images can often be very large in size and thus difficult to store or transfer.

What are CG4 files?

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.
