QImageIO - question

Hi, 

I want to read Images (eg. file.bmp) from a connected socket s.
I use the code below. But qimageio.read() returns FALSE.
The communication partner opens a file.bmp in binary mode and sends it to the 
socket.

What goes wrong ?

QSocket qsocket;
qsocket.setSocket(s);
QImageIO qimageio;
qimageio.setIODevice(&qsocket);
qimageio.setFormat(text);
if( qimageio.read() )
...

Yours:
Rainer Lehrig

What are the contents of "text"?

Have you tried without the call to setFormat()?
