amount as the original translation. This is equivalent to the
following sequence of calls:
translate(x, y); rotate(theta); translate(-x, -y);Rotating with a positive angle theta rotates points on the positive x axis toward the positive y axis.

AffineTransform
object with the
Transform
in this Graphics2D
according
to the rule last-specified-first-applied. If the current
Transform
is Cx, the result of composition
with Tx is a new Transform
Cx'. Cx' becomes the
current Transform
for this Graphics2D
.
Transforming a point p by the updated Transform
Cx' is
equivalent to first transforming p by Tx and then transforming
the result by the original Transform
Cx. In other
words, Cx'(p) = Cx(Tx(p)). A copy of the Tx is made, if necessary,
so further modifications to Tx do not affect rendering.

A scaled version of an image will not necessarily be available immediately just because an unscaled version of the image has been constructed for this output device. Each size of the image may be cached separately and generated from the original data in a separate image production sequence.

ImageObserver.imageUpdate(java.awt.Image, int, int, int, int, int)
public boolean drawImage(java.awt.Image img, int x, int y, java.awt.Color bgcolor, java.awt.image.ImageObserver observer)
This operation is equivalent to filling a rectangle of the width and height of the specified image with the given color and then drawing the image on top of it, but possibly more efficient.
This method returns immediately in all cases, even if the complete image has not yet been loaded, and it has not been dithered and converted for the current output device.
If the image has not yet been completely loaded, then
drawImage
returns false
. As more of
the image becomes available, the process that draws the image notifies
the specified image observer.

The image is drawn inside the specified rectangle of this graphics context's coordinate space, and is scaled if necessary. Transparent pixels are drawn in the specified background color. This operation is equivalent to filling a rectangle of the width and height of the specified image with the given color and then drawing the image on top of it, but possibly more efficient.
This method returns immediately in all cases, even if the
entire image has not yet been scaled, dithered, and converted

This method always uses the unscaled version of the image to render the scaled rectangle and performs the required scaling on the fly. It does not use a cached, scaled version of the image for this operation. Scaling of the image from source to destination is performed such that the first coordinate of the source rectangle is mapped to the first coordinate of the destination rectangle, and the second source coordinate is mapped to the second destination coordinate. The subimage is scaled and flipped as needed to preserve those mappings.

applying a transform from image space into user space before drawing.
The transformation from user space into device space is done with
the current Transform
in the Graphics2D
.
The specified transformation is applied to the image before the
transform attribute in the Graphics2D
context is applied.
The rendering attributes applied include the Clip
,
Transform
, and Composite
attributes. Note
that no rendering is done if the specified transform is
noninvertible.
Rendering hints set on the Graphics2D
object might
be used in rendering the RenderableImage
.
If explicit control is required over specific hints recognized by a
specific RenderableImage
, or if knowledge of which hints
are used is required, then a RenderedImage
should be
obtained directly from the RenderableImage
and rendered using
drawRenderedImage
.
