use of java.awt.image.ReplicateScaleFilter in project jdk8u_jdk by JetBrains.
the class Image method getScaledInstance.
/**
* Creates a scaled version of this image.
* A new <code>Image</code> object is returned which will render
* the image at the specified <code>width</code> and
* <code>height</code> by default. The new <code>Image</code> object
* may be loaded asynchronously even if the original source image
* has already been loaded completely.
*
* <p>
*
* If either <code>width</code>
* or <code>height</code> is a negative number then a value is
* substituted to maintain the aspect ratio of the original image
* dimensions. If both <code>width</code> and <code>height</code>
* are negative, then the original image dimensions are used.
*
* @param width the width to which to scale the image.
* @param height the height to which to scale the image.
* @param hints flags to indicate the type of algorithm to use
* for image resampling.
* @return a scaled version of the image.
* @exception IllegalArgumentException if <code>width</code>
* or <code>height</code> is zero.
* @see java.awt.Image#SCALE_DEFAULT
* @see java.awt.Image#SCALE_FAST
* @see java.awt.Image#SCALE_SMOOTH
