Converting JPM to CAL

JPM is an image format included in the JPEG2000 group, together with a series of others such as JPX, JP2 and JPF. JPEG2000 represents a standard of rendering the image, released in the year 2000 as an upgrade of the JPEG format, using a type of technology called "wavelet compression", which delivers an improved quality/size ratio. JPM was designed for documents with several pages including several objects, and hence it is processed by reaConverter as a multi-page format.

A CAL image file represents a monochrome bitmap image that uses the CALS raster image standard for storing graphics data. This standard was created in the 1980s by the US Department of Defence as a compressed interchangeable image format. CAL and CALS are extensions used for similar purposes.
