Field Detail

NO_OP

public static final int NO_OP

End the path object without filling or stroking it. This operator shall be a path-painting no-op, used primarily for the side effect of changing the current clipping path

See Also:

Constant Field Values

STROKE

public static final int STROKE

Value specifying stroke operation to perform on the current path.

See Also:

Constant Field Values

FILL

public static final int FILL

Value specifying fill operation to perform on the current path. When the fill operation is performed it should use either nonzero winding or even-odd rule.

Constructor Detail

PathRenderInfo

public PathRenderInfo(Stack<CanvasTag> canvasTagHierarchy,
                      CanvasGraphicsState gs,
                      Path path,
                      int operation,
                      int rule,
                      boolean isClip,
                      int clipRule)

Creates the new PathRenderInfo instance.

Parameters:

canvasTagHierarchy - the canvas tag hierarchy

gs - the graphics state

path - the path to be rendered

operation - one of the possible combinations of STROKE and FILL values or NO_OP

rule - either PdfCanvasConstants.FillingRule.NONZERO_WINDING or PdfCanvasConstants.FillingRule.EVEN_ODD

isClip - true indicates that current path modifies the clipping path

clipRule - either PdfCanvasConstants.FillingRule.NONZERO_WINDING or PdfCanvasConstants.FillingRule.EVEN_ODD

PathRenderInfo

public PathRenderInfo(Stack<CanvasTag> canvasTagHierarchy,
                      CanvasGraphicsState gs,
                      Path path,
                      int operation)

If the operation is NO_OP then the rule is ignored, otherwise PdfCanvasConstants.FillingRule.NONZERO_WINDING is used by default. With this constructor path is considered as not modifying clipping path.

See PathRenderInfo(Stack, CanvasGraphicsState, Path, int, int, boolean, int)

Parameters:

canvasTagHierarchy - the canvas tag hierarchy

gs - the graphics state

path - the path to be rendered

operation - one of the possible combinations of STROKE and FILL values or NO_OP
