4.1 Algorithm

Step 1: Read the Binary image.

Step 2: Find the position vectors of the black pixels of the Binary image.

Step 3: Transform the position vectors using the transformation matrix to
obtain the new sets of positions.

Step 4: Create the blank image completely filled up with white pixels. Fill
the selected pixels of the blank image described by the positions
obtained in step 3 with black to obtain the rotated image.
