Method Detail

dispose

void dispose()

release resources associated with this object.

Specified by:

dispose in interface Renderer

updateOffScreen

void updateOffScreen(int width,
                     int height)

Update the required size of the offscreen buffer.

setTransform

void setTransform(java.awt.geom.AffineTransform usr2dev)

Sets the transform from the current user space (as defined by the top node of the GVT tree, to the associated device space.

Specified by:

setTransform in interface Renderer

Parameters:

usr2dev - the new user space to device space transform. If null, the identity transform will be set.

getTransform

java.awt.geom.AffineTransform getTransform()

Returns the transform from the current user space (as defined by the top node of the GVT tree) to the device space.

Specified by:

getTransform in interface Renderer

setRenderingHints

void setRenderingHints(java.awt.RenderingHints rh)

Sets the specified rendering hints to be used for future renderings. This replaces current set of rendering hints.

Parameters:

rh - the rendering hints to use

getRenderingHints

java.awt.RenderingHints getRenderingHints()

Returns the rendering hints this ImageRenderer is using for its rendering.

Returns:

the rendering hints being used

getOffScreen

java.awt.image.BufferedImage getOffScreen()

Get the Current offscreen buffer used for rendering

clearOffScreen

void clearOffScreen()

Tells renderer to clear current contents of offscreen buffer

flush

void flush()

Flush any cached image data (preliminary interface).

flush

void flush(java.awt.Rectangle r)

Flush a rectangle of cached image data (preliminary interface).

flush

void flush(java.util.Collection areas)

Flush a list of rectangles of cached image data (preliminary interface). Each area are transformed via the usr2dev's renderer transform before the flush(Rectangle) is called.
