示例1: filterImage

private BufferedImage filterImage(BufferedImage original, int hash, RescaleOp op) {
HashMap<Integer, BufferedImage> imageMap = imageFilterBuffer.get(hash);
float[] scaleFactors = op.getScaleFactors(null);
int opHash = (int) (10*scaleFactors[0]+100*scaleFactors[1]+1000*scaleFactors[2]+10000*scaleFactors[3]);
if(imageMap != null) {
if(imageMap.size() > MAX_IMAGE_BUFFER_SIZE) emptyImageBuffer(); // empty image buffer of this image if it is too full.
else if(imageMap.containsKey(opHash)) return imageMap.get(opHash); // return the buffered resized image if it was resized before.
}
