Examples with AreaAveragingScaleFilter java.awt.image.AreaAveragingScaleFilter used on opensource projects

Example 1 with AreaAveragingScaleFilter

use of java.awt.image.AreaAveragingScaleFilter 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.
