Examples of org.axsl.ps.PsInput

org.axsl.ps.PsInput
Interface for objects that wish to be used as input to the PostScript interpreter. This interface is needed because a variety of file types may be used as input to a PostScript interpreter. For example, Type 1 font files are frequently packaged in operating-system-specific wrapper files that must be unwrapped (and sometimes decoded) before they can be consumed by the PostScript interpreter. This interface allows other classes to do that work and pass the results through to the interpreter. Please note that the implementing class is responsible for any buffering of the data for i/o efficiency purposes.
