i want write a code in C without using OpenCV library to code a Sobel operator to calculate the magnitude and direction of the gradient of an image then use pseudo color to display them using intensity for magnitude and hue for direction display input and output images

how to write a function of image rotation by using the following f is the input image, (x0,y0) is the rotating center & a is the rotating angle. Return value is the output image (using IM & Bilinear interpolation);

how to rotate image using c-- following this byte[,] rotation(byte[,]f, float x0,float y0,float a); f is the input image, (x0,y0) is the rotating center & a is the rotating angle. Return value is the output image (using IM & Bilinear interpolation);
