Constructor Detail
PSState
public PSState()(Code)
Default constructor



PSState
public PSState(PSState org, boolean copyTransforms)(Code)
Copy constructor
Parameters:
  org - the original to copy from
Parameters:
  copyTransforms - true if the list of matrix concats should be cloned, too




Method Detail
checkTransform
public boolean checkTransform(AffineTransform tf)(Code)
Check the current transform. The transform for the current state is the combination of all transforms in the current state. The parameter is compared against this current transform.
Parameters:
  tf - the transform the check against true if the new transform is different then the current transform



concatMatrix
public void concatMatrix(AffineTransform transform)(Code)
Concats the given transformation matrix with the current one.
Parameters:
  transform - The new transformation matrix



getTransform
public AffineTransform getTransform()(Code)
Returns the transform. the current transformation matrix



reestablish
public void reestablish(PSGenerator gen) throws IOException(Code)
Reestablishes the graphics state represented by this instance by issueing the necessary commands.
Parameters:
  gen - The generator to use for output
exception:
  IOException - In case of an I/O problem



useColor
public boolean useColor(Color value)(Code)
Establishes the specified color (RGB).
Parameters:
  value - color as defined by the setrgbcolor command true if the color changed compared to the previous setting



useDash
public boolean useDash(String pattern)(Code)
Establishes the specified dash.
Parameters:
  pattern - dash pattern as defined by the setdash command true if the dash pattern changed compared to the previous setting



useFont
public boolean useFont(String name, float size)(Code)
Establishes the specified font and size.
Parameters:
  name - name of the font for the "F" command (see FOP Std Proc Set)
Parameters:
  size - size of the font true if the font changed compared to the previous setting



useLineCap
public boolean useLineCap(int value)(Code)
Establishes the specified line cap.
Parameters:
  value - line cap (0, 1 or 2) as defined by the setlinecap command true if the line cap changed compared to the previous setting



useLineWidth
public boolean useLineWidth(double value)(Code)
Establishes the specified line width.
Parameters:
  value - line width as defined by the setlinewidth command true if the line width changed compared to the previous setting
