how can i convert an image to bit stream

hey all is ther any way to convert image to bit stream or to ASCII code ?? please i need ur help thanks in advance

If the image is converted to uint8() format (simply by taking uint8(Image)), it is already in ASCII format-- you can then reshape() the resulting matrix into a single row/column to get a byte stream. Something like this:

Image8 = reshape(uint8(YourImageMatrix), 1, []);

Note that if you have an indexed image, this will saturate your image at 255 unless you have converted it to RGB before, using ind2rgb().

Technically not: ASCII is only from 0 to 127, not 0 to 128. Also note that not all ASCII characters are printable, and that some ASCII characters (such as NUL or IDLE) may be "eaten" by communications systems.

To transform a data array to printable ASCII, using "uuencode" or the like is recommended.

Now what?
