Remember in the days when graphics cards had limited amount of
pixels, and the graphic bitmaps had graphic lookup tables?
For those of us who do, we also remember Color Table Animation, a
cute trick where we created animation not by modifying the bits in
the bitmap, but by modifying the content of the color lookup table.
If you rotated the values, you would create a cool Rainbow pattern
rotation.
Has anyone create this same effect using NSImages (or possibly Core
Images)? Has anyone posted any source code examples? Most image
manipulation is with 24 bits per pixel data, where there is no color
lookup table. If anyone would have some suggestions or examples, I
would appreciate it.
Thank you,
