yes, thanks everyone it made sens last night when I got to bed for a
while...:)
yes it's just an image where color are black or
white....1/0...binary-coded...wow! :)
Only for processing, not less space...
thanks ;)

Hi,
BitmapData class has a threshold method that does what Ashim mentioned which
if you were to go to the extreme 0 and 255 of a pixel value you'd ultimately
obtain a black and white image anyway. Main use of thresholding however is
for image processing purposes which I will not go in depth here and not
really to help save size because you won't be able to get your image back
unless you save the pixel values of the original.
I'm guessing you might mean using the ByteArray class which can be used to
store binary data and has a built-in compress method to boot.
HTH
Thanks & Best regards,
Daniel Boey

If you're just after the look the TweenFilterLite library has a great
inbuilt filter. But if you actually want to convert it, I imagine you'd
just
run through every pixel and if the value (calculated however you'd like) is
greater than your decided threshold, make it white, else black. I'm not
sure
what it will save you within flash however.
