takepic Function Specifications

-----------------------------------

Can someone possibly tell me how the pixel data is stored in the integer array when you use the takepic function?

Any information would be appreicated.

Well, Turing first takes your picture and then squishes it so that it is really small and then chops it up into equal slices to fit in the integer arrray! :wink:  :D 

Seriously, takepic works by recording the pixel values in your rectangular area that you define in the procedure.

I know what it does, and I've taken a look at the integer values...

For example, the first 18 (or was it 22, haven't worked on it in a while) values store the data describing the picture and that the pixel data does not start until afterwards.  

The pixel data is stored with the colour's r, g, b component each being multiplied by 256 and stored as r * 2^16 + g * 2 ^ 8 + b.

In the header there is also data stored about the image size....

But that's all I know about it for now, I want to be able to master the format so I can say.... take an image, and create slices of it and being able to manipulate them without drawing it on the screen.
