There is clear description for image rotation in the book titled "Digital Media Processing:DSP Algorithms using C", from Newnes publishers

do u have a source to get it

I have a problem i wanted to rotate a picture and calculate the time taken using "C" programming language ..Its really very urgent .. Please help me out ..

USE the trigonometric equation on every pixel location and find out new location then place the pixel there,, u can achieve it simply like this. take care of hight and width changes,
zero padding at line endings of the BMP, BMP data structure.

hey u can rotate an image by using c,,,just use geometric equations and u must have a good knowkedge about cordinate systems , and frame of referances ..i achived it .but the problem is that it losses quality..
there is a problem when rounding the digit .. if u have any doubt u pls mail me...
