Re: new Wiki File

Hi Dominic,

A small correction for the description with camera_get_image:

"
To retrieve the red value use: image[i] & 0xff0000 To retrieve the
green value use: image[i] & 0x00ff00 To retrieve the blue value use:
image[i] & 0x0000ff 
"

For green and blue you need to mask of the higher color bits, so use:
 green => image[i] & 0x00ff00 
 blue  => image[i] & 0x0000ff 

To get values from 0..255, you need to do some bitshifting too:
 red   = (image[i] & 0xff0000)>>16
 green = (image[i] & 0x00ff00)>>8 
 blue  =  image[i] & 0x0000ff
