Class TXTState

java.lang.Object
org.apache.fop.render.txt.TXTState
public class TXTState extends Object

    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.
    Point
    transformPoint(int x, int y)
    Transforms point (x, y) using resultCTM.
    Point
    transformPoint(Point p, CTM ctm)
    Transforms point using ctm.
