I thought if I could extract the RGB values from pixels in a picture I
could solve my concern about storing a password that may be read by
someone peaking at the source code of a built rev app.
So I take a short text string
repeat through each character in the string
convert each character to a number using chartoNum()
get the value of that pixel in a particular image ("red" value for even
numbers and "green" value for odd numbers)
convert the returned number to a character using numtochar()
put the original char and the returned pixel colour (converted to a
character) after a temp string to build up a new string
base64encode the new string and use that as my password. :-)
Cheers

Check out the mouseColor function, which returns the color of the
pixel directly under the mouse
If you're looking to figure out the color of the pixel 4,12 in the
image, then you'll need to calculate it using the imageData and the
rect of the image.
best,
