OOP JpegScaler API : Java API for scaling JPEG image by Java Advanced Imaging API (JAI)
Java API for scaling JPEG image by Java Advanced Imaging API (JAI). The width/hight of the JPEG image will be reduced to fit within the specified rectangle. The ratio of width/height of the original JPEG image will be left unchanged. This Java API is useful to show the large JPEG image on the small screen of the WAP phone. For example, your Servlet can send the binary contents of the scaled JPEG image to the WAP device.
