示例1: zoom

/**
* Filters the entire source image.
*
* This is a convenience function which calls
* {@link zoom(WritableRaster, Rectangle, BufferedImage, Filter)},
* setting the destination rectangle as the bounds of the destination
* tile.
*
* @param dst the destination rectangle
* @param src the soure image
* @param filter the filter to apply
* @throws ClassCastException if <code>src</code> does not store its data
* in a {@link DataBufferInt}
*/
