Interface IPdfBoxGraphics2DDrawControl

All Known Implementing Classes:

PdfBoxGraphics2DDrawControlDefault

public interface IPdfBoxGraphics2DDrawControl

Allows you to influence the fill and draw operations. You can alter the shape to draw/fill, you can even filter out the complete draw/fill operation. And you can draw additional stuff after the draw/fill operation, e.g. to implement overfill.

Method Detail

transformShapeBeforeFill

Shape transformShapeBeforeFill(Shape shape,
                               IPdfBoxGraphics2DDrawControl.IDrawControlEnv env)

You may optional change the shape that is going to be filled. You can also do other stuff here like drawing an overfill before the real shape.

Parameters:

shape - the shape that will be drawn

env - Environment

Returns:

the shape to be filled. If you return null, nothing will be filled

transformShapeBeforeDraw

Shape transformShapeBeforeDraw(Shape shape,
                               IPdfBoxGraphics2DDrawControl.IDrawControlEnv env)

You may optional change the shape that is going to be drawn. You can also do other stuff here like drawing an overfill before the real shape.

Parameters:

shape - the shape that will be drawn

env - Environment

Returns:

the shape to be filled. If you return null, nothing will be drawn

afterShapeFill

void afterShapeFill(Shape shape,
                    IPdfBoxGraphics2DDrawControl.IDrawControlEnv env)

Called after shape was filled. This method is always called, even if transformShapeBeforeFill(java.awt.Shape, IDrawControlEnv) returns null.

Parameters:

shape - the shape that was filled. This is the original shape, not the one transformed by transformShapeBeforeFill(java.awt.Shape, IDrawControlEnv).

env - Environment

afterShapeDraw

void afterShapeDraw(Shape shape,
                    IPdfBoxGraphics2DDrawControl.IDrawControlEnv env)

Called after shape was drawn. This method is always called, even if transformShapeBeforeDraw(java.awt.Shape, IDrawControlEnv) returns null.

Parameters:

shape - the shape that was drawn. This is the original shape, not the one transformed by transformShapeBeforeDraw(java.awt.Shape, IDrawControlEnv).

env - Environment
