paintToBufferedImage
protected java.awt.image.BufferedImage paintToBufferedImage(org.apache.xmlgraphics.java2d.Graphics2DImagePainter painter,
RendererContext.RendererContextWrapper context,
int resolution,
boolean gray,
boolean withAlpha)
- Paints the image to a BufferedImage and returns that.
- Parameters:
painter
- the painter which will paint the actual imagecontext
- the renderer context for the current rendererresolution
- the requested bitmap resolutiongray
- true if the generated image should be in grayscaleswithAlpha
- true if an alpha channel should be created
- Returns:
- the generated BufferedImage
setRenderingHintsForBufferedImage
protected void setRenderingHintsForBufferedImage(java.awt.Graphics2D g2d)
- Sets rendering hints on the Graphics2D created for painting to a BufferedImage. Subclasses
can modify the settings to customize the behaviour.
- Parameters:
g2d
- the Graphics2D instance
paintImage
public void paintImage(Graphics2DImagePainter painter,
RendererContext context,
int x,
int y,
int width,
int height)
throws java.io.IOException
- Paints an arbitrary images on a given Graphics2D instance. The renderer
providing this functionality must set up a Graphics2D instance so that
the image with the given extents (in mpt) can be painted by the painter
passed to this method. The Graphics2DImagePainter is then passed this
Graphics2D instance so the image can be painted.
- Specified by:
paintImage
in interface Graphics2DAdapter
- Parameters:
painter
- the painter which will paint the actual imagecontext
- the renderer context for the current rendererx
- X position of the imagey
- Y position of the imagewidth
- width of the imageheight
- height of the image
- Throws:
java.io.IOException
- In case of an I/O error while writing the output format
