Paints the image to a BufferedImage and returns that.

Parameters:

painter - the painter which will paint the actual image

targetDimension - the target dimensions of the image to be converted to a bitmap

resolution - the requested bitmap resolution

gray - true if the generated image should be in grayscales

withAlpha - 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 behavior.

Parameters:

g2d - the Graphics2D instance
