java.awt.geom.Rectangle2D |
getBounds2D()
Returns the bounds of this Rable in the user coordinate system.

GraphicsNode |
getGraphicsNode()
Returns the
GraphicsNode rendered by this image |
boolean |
isDynamic()
Returns true if successive renderings (that is, calls to
createRendering() or createScaledRendering()) with the same arguments
may produce different results.

public java.awt.image.RenderedImage createRendering(java.awt.image.renderable.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.
renderContext
- the RenderContext to use to produce the rendering.Copyright © 2022 Apache Software Foundation. All Rights Reserved.
