Method Details

updateCtm

             public void updateCtm
             (Matrix newCtm)
            

Description copied from class: CanvasGraphicsState

Updates current transformation matrix.

Overrides:

updateCtm in class CanvasGraphicsState

Parameters:

newCtm - new current transformation matrix.

clip

             public void clip
             (Path path, int fillingRule)
            

Intersects the current clipping path with the given path.

Note: Coordinates of the given path should be in the transformed user space.

Parameters:

path - The path to be intersected with the current clipping path.

fillingRule - The filling rule which should be applied to the given path. It should be either PdfCanvasConstants.FillingRule.EVEN_ODD or PdfCanvasConstants.FillingRule.NONZERO_WINDING

getClippingPath

             public Path getClippingPath()
            

Getter for the current clipping path.

Note: The returned clipping path is in the transformed user space, so if you want to get it in default user space, apply transformation matrix (CanvasGraphicsState.getCtm()).

Returns:

The current clipping path.

setClippingPath

             public void setClippingPath
             (Path clippingPath)
            

Sets the current clipping path to the specified path.

Note:This method doesn't modify existing clipping path, it simply replaces it with the new one instead.

Parameters:

clippingPath - New clipping path.
