javax.media.jai.RenderableGraphics
public class RenderableGraphics
An implementation of Graphics2D
with
RenderableImage
semantics. In other words, content may be
drawn into the image using the Graphics2D
interface and later
be turned into RenderedImage
s with different resolutions and
characteristics.
A RenderableGraphics
occupies a region of the plane
specified at the time of construction.
The contents of RenderableImage
s that are drawn onto a
RenderableGraphics
are accessed only at the time of rendering,
not the time of drawing.
Since the methods of this class all derive from Graphics2D
and RenderableImage
, they are not all commented individually.

public RenderedImage createRendering(RenderContext renderContext)
The created RenderedImage may have a property identified by the String HINTS_OBSERVED to indicate which RenderingHints (from the RenderContext) were used to create the image. In addition any RenderedImages that are obtained via the getSources() method on the created RenderedImage may have such a property.
The bounds of the RenderedImage
are determined from
the dimensions parameter passed to the RenderableGraphics
constructor. These bounds will be transformed by any
AffineTransform
from the RenderContext
.
The RenderingHints
from the RenderContext
may
be used to specify the tile width and height, SampleModel
,
and ColorModel
by supplying an ImageLayout
hint. The precedence for determining tile width and height is to use
firstly values provided explicitly via the ImageLayout
,
secondly the width and height of the SampleModel
in the
hint, and thirdly the bounds of the RenderableGraphics
object after transformation.
If either the SampleModel
or ColorModel
is null, an attempt will be made to derive a compatible value for the
null object from the non-null object. If they are both null, a 3-band
byte TiledImage
with a null ColorModel
and a
PixelInterleavedSampleModel
will be created.
