Class BufferedImageBackgroundPainterStrategy
java.lang.Object
org.fife.ui.rtextarea.ImageBackgroundPainterStrategy
org.fife.ui.rtextarea.BufferedImageBackgroundPainterStrategy
- All Implemented Interfaces:
- BackgroundPainterStrategy
public class BufferedImageBackgroundPainterStrategy
- extends ImageBackgroundPainterStrategy
A strategy for painting the background of an RTextAreaBase
as an image. The image is always stretched to completely fill the
RTextAreaBase
.
A java.awt.image.BufferedImage
is used for rendering;
theoretically, for performance you should use
java.awt.image.VolatileImage
; see
org.fife.ui.RTextArea.VolatileImageBackgroundPainterStrategy
for this.
You can set the scaling hint used when stretching/skewing the image
to fit in the RTextAreaBase
's background via the
setScalingHint
method, but keep in mind the more
accurate the scaling hint, the less responsive your application will
be when stretching the window (as that's the only time the image's
size is recalculated).
