Manju,
When you rotate an image by any non-right angle (not
multiple of 90 degrees), the corners of the resulting image need to be filled
with something.
What exactly do you want to put there?
Please note that there is no special part of the image called
'background' that you can rotate without changing it, unless the image has a
majority area filled with a special color or pattern. In that case, you need to
rotate first, then fill the corners with this special color or pattern.

Manju,
What exactly do you mean by transparent color?
Are you trying to save a GIF or PNG image that has a
transparent color defined? If yes, simply pass the value of your transparent
color as the fill color of the rotate function.
