This function derives the content of the object as it will be
inserted into the final PDF document.
There are many ways in which a string may be represented. The
format string allows more control over how this is done.
The following options may be used in combination.
- nXX - the number of items per line where XX is the number
If format options are not specified then ABCpdf will select a
sensible set depending on context.
The number of items per line, determines how many array items
will be written on one line. If the number is less than or equal to
zero then ABCpdf will dynamically determine an appropriate number
of items to be written. Note that items may themselves be ArrayAtom
or DictAtom so they may contain their own line breaks.
