Converting CALS to APNG

The CALS image format includes a compressed raster/bitmap file. Though considered rare by mainstream users, CALS files are used by many document-handling, DTP and image processing applications employed by the US government. The format itself was created by the Department of Defense as a standard for storing an interchanging graphics data. CALS stands for "Computer Aided Acquisitions and Logistics Support", which is an office inside the Department of Defense.

The APNG format is also known as "animated PNG" and is made up of a series of PNG files of the same size that are connected as an animation. APNG files are similar in function with GIFs, but they support better quality images and transparency.

So, how to change CALS into APNG?
