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
-
mpt2px
protected int mpt2px(int unit, int resolution)
Converts millipoints to pixels- Parameters:
unit
- the unit to convert in mptsresolution
- the target resolution- Returns:
- the converted unit in pixels
-
createGrayBufferedImageWithAlpha
private static java.awt.image.BufferedImage createGrayBufferedImageWithAlpha(int width, int height)
-
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
Deprecated.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 interfaceGraphics2DAdapter
- 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
