Re: [Flashcoders] binary-coded image
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 white1/0...binary-coded...wow! :) Only for processing, not less space... thanks ;) L Daniel Boey a écrit : 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.

Re: [Flashcoders] binary-coded image
No it's more like to obtein a treshold image...I just read that in a publication, in a book... "The reason why the input image is converted to a binary-coded image is because binary-coded image requires less data size than color or B&W image." get not more clue with google :) L David Hershberger a écrit : Also Flex supports PNG and JPEG: mx.graphics.codec.PNGEncoder and mx.graphics.code.JPEGEncoder.

If you mean 'how do I encode a bitmap into an image format' e.g. PNG or JPEG, check out this library: http://code.google.com/p/as3corelib/wiki/Main which has code for both PNG and JPEG.
