Image Reading and Writing in GNU Radio

Dear all,
I want to transmit an image over wireless link, so I need two blocks: +
one for reading grayscale image and giving out a bit stream+ the other
one take a bit stream as input and rebuild the image
Is there any completed toolbox containing blocks employing these
functions? If none, could you give me some clue for writing my necessary
blocks?
Thanks in advance,Hoang

I guess if you save the image in a non-compressed, grayscale format this
should come for free.

There is no block for this. If your application doesn’t have to be super
high speed, I recommend using matplotlib and Python blocks. Using those
is ridiculously easy (makes Matlab look hard).

Otherwise you’ll have to build something using Qwt, which is harder
unless you’re really good at Qt.
