Convert a picture to a bit stream

[tintin99]

Hi

I would like to convert a picture to a bit stream . I know for example for text to bit we can use "Text to unsigned byte array" block  but I don't know how to do it with lets say a JPG (or any other format). I would greatly appreciate your help with coding or a basic example

If you have the jpg image as a file you can just read the file using the standard file functions (read binary file). This will return a string. If you need it as byte array you can use the function you mentioned or read the binary file that way.

Thanks Dan. Would you please show me how to do it in a very basic example. I tried it didn't work for me.

It's really simple, see snippet.

Great .Many thanks. Would you please also let me know how can I recover the picture from bit stream or Text to  JPG again

Just write the text to a binary file using the corresponding function (Write to Binary File).

I tried this code but it is not working

In the write primitve, set "prepend array or string size" to False, else it will add 4 extra bytes at the beginning of the file.
