getFasterScaledInstance

public static java.awt.image.BufferedImage getFasterScaledInstance(java.awt.image.BufferedImage img,
                                                                   int targetWidth,
                                                                   int targetHeight,
                                                                   java.lang.Object hint,
                                                                   boolean progressiveBilinear)

Convenience method that returns a scaled instance of the provided BufferedImage.

Parameters:

img - the original image to be scaled

targetWidth - the desired width of the scaled instance, in pixels

targetHeight - the desired height of the scaled instance, in pixels

hint - one of the rendering hints that corresponds to RenderingHints.KEY_INTERPOLATION (e.g. RenderingHints.VALUE_INTERPOLATION_NEAREST_NEIGHBOR, RenderingHints.VALUE_INTERPOLATION_BILINEAR, RenderingHints.VALUE_INTERPOLATION_BICUBIC)

progressiveBilinear - if true, this method will use a multi-step scaling technique that provides higher quality than the usual one-step technique (only useful in down-scaling cases, where targetWidth or targetHeight is smaller than the original dimensions)

Returns:

a scaled version of the original BufferedImage
