Class TXTState


  • public class TXTState
    extends java.lang.Object
    This keeps information about the current state when writing to txt, i.e. manages coordinate transformation matrices for getting absolute coordinates.

      Modifier and Type Method Description
      CTM getResultCTM()  
      void pop()
      Pop the coordinate transformation matrix from the stack and reevaluate resultCTM.
      void push​(CTM ctm)
      Push the current coordinate transformation matrix onto the stack and reevaluate resultCTM.
      CTM refineCTM​(CTM ctm)
      Modifies coordinate transformation matrix in such a way, so x-shift and y-shift will be transformed in text positions.
      java.awt.Point transformPoint​(int x, int y)
      Transforms point (x, y) using resultCTM.
      java.awt.Point transformPoint​(java.awt.Point p, CTM ctm)
      Transforms point using ctm.
