Split the Image jai_core.jar

[jayjain]

HI

I am splitting the image, means one image contains 10 page so it will be in 10 file. I am using jai_core.jar and jai_codec.jar.
Currently I am using (.TIF) file for this purpose. But one image split takes around 26 sec. If any body help me to reduce the time line.

I f I use GIF or JPG or any other extension, Will it reduce some time or not.

Thanks in advance.
