Could you please look at the algorithm I just figured out and tell me
what you think of it.
If there's a better method, or anything, please let me know.
I am dealing with 1 bit per pixel images.

90 degree rotation

1. Imagewidth := pixels per row
2. Imageheight := pixels per column
3. Newrownumber := imageheight � rownum +1
4. Firstpixelinrow := imagewidth * (rownumber-1) +1
5. Pixelnuminrow := pixelnum � first pixel in row
6. Newpixelnum := pixelnuminrow * imageheight+newrownumber;
7. CorrectByte := newpixelnum div 8 + 1;
8. Allocate enough memory for new image
9. Fill the memory with 0�s
10. AND the current byte to get the current pixel
11. OR the current Pixel with the Byte you want to put it into
12. Do this for entire image.
