Method Detail

setGraphics

public void setGraphics(java.awt.Graphics2D g)

Set the Graphics2D object that will do all the rendering.

getGraphics

public java.awt.Graphics getGraphics()

Description copied from class: PDFMarkupHandler

Return an awt Graphics object which will be used for suspect purposes. TODO: this is really to help get the FontMetrics for a given font

Specified by:

getGraphics in class PDFMarkupHandler

setDestinationRect

public void setDestinationRect(java.awt.geom.Rectangle2D r)

Set the bounds in the Graphics2D's coordinate system where the page will be drawn.

beginPage

public void beginPage(float width,
                      float height)

Set the bounds of the page. This will be called before any marking operations.

Specified by:

beginPage in class PDFMarkupHandler

endPage

Overrides:

endPage in class PDFMarkupHandler

clipChanged

public void clipChanged(PDFGState g)

reset the clip

strokePath

public void strokePath(PDFGState g,
                       java.awt.geom.GeneralPath p)

Stroke the current path with the current miter limit, color, etc.

Specified by:

strokePath in class PDFMarkupHandler

fillPath

public void fillPath(PDFGState g,
                     java.awt.geom.GeneralPath p)

Fill the current path using the fill params in the gstate

Specified by:

fillPath in class PDFMarkupHandler

drawImage

public void drawImage(PDFGState g,
                      java.awt.Image i,
                      java.awt.geom.AffineTransform ixform)

Draw an image

Specified by:

drawImage in class PDFMarkupHandler

drawTiledImage

public void drawTiledImage(PDFTiledImage.TiledImageProxy i,
                           java.awt.geom.AffineTransform ixform)

sun_bug_4723021_workaround

public void sun_bug_4723021_workaround(java.awt.Image i,
                                       java.awt.geom.AffineTransform ixform)

http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4723021

Applying a transform to an image with interesting SampleModels fails. To work around this, we try creating an untransformed RGBA image first and then redrawing that with the desired transform.

showText

public void showText(PDFGState g,
                     java.awt.font.GlyphVector v)

Draw some text at the current text position. The glyphVector will have been created by the parser using the current font and its character encodings.

Specified by:

showText in class PDFMarkupHandler

getFontRenderContext

public java.awt.font.FontRenderContext getFontRenderContext()

Description copied from class: PDFMarkupHandler

Return an awt FontRenderContext object which will be used to render the fonts. The same rendercontext is used for the entire page.

Specified by:

getFontRenderContext in class PDFMarkupHandler
