Constructor Details

ParserGraphicsState

ParserGraphicsState()

Internal empty and default constructor.

ParserGraphicsState

ParserGraphicsState(ParserGraphicsState source)

Copy constructor.

Parameters:

source - the Graphics State to copy from

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.

transformClippingPath

private void transformClippingPath(Matrix newCtm)
