The solution writes the image into an opened file. The file format might fail to work on certain [[OS]]es, because output might mangle control characters like LF, CR, FF, HT, VT etc. The OS might also limit the line length of a text file. In general it is a bad idea to mix binary and text output in one file. This solution uses ''stream I/O'', which should be as portable as possible.

The static file provides templates for writing a PPM in either raw or plain format, regardless of what type you use to represent a pixel. The dynamic file, however, provides implementations ''only'' for the <code>rgb24</code> type defined in <code>bitmap_task.sats</code>.
