getSoftFont

public PCLSoftFont getSoftFont(Typeface font,

Finds a soft font associated with the given typeface. If more than one instance of the font exists (as each font is bound and restricted to 255 characters) it will find the last font with available capacity.

Parameters:

font - The typeface associated with the soft font

Returns:

Returns the PCLSoftFont with available capacity

countNonMatches

private int countNonMatches(PCLSoftFont font,
 String text)

                  throws IOException

Throws:

IOException
