Method Detail

convertDimen

long convertDimen(Context context,
                  TokenSource source,
                  Typesetter typesetter)
                  throws ConfigurationException,
                         HelpingException,
                         TypesetterException

This method converts a register into a dimen. It might be necessary to read further tokens to determine which value to use. For instance an additional register number might be required. In this case the additional arguments Context and TokenSource can be used. The return value is the length in scaled points.

Parameters:

context - the interpreter context

source - the source for new tokens

typesetter - the typesetter to use for conversion

Returns:

the converted value in sp

Throws:

ConfigurationException - in case of an configuration error

HelpingException - in case of an error

TypesetterException - in case of an error in the typesetter
