Class PDFForm

java.lang.Object
com.inductiveautomation.rm.pdf.reader.PDFForm
public class PDFForm extends Object
An object which holds on to a stream of markup operations for later drawing. In PDF a form xobject is a stream. This object saves the stream data and when it comes time to draw, the PageParser will parse the stream. The tokens returned by the lexing portion of the parsing will be held on to by the PDFForm so that the markup operations can be executed over and over without repeating that step. This method can be used by form xobjects as well as pattern colorspaces.
