In which segment of a .jpeg stores QImageWriter the data?
I searched in the commend segment (FF FE COM Comments) but i could't find any data.
what data? the compression settings etc ?
to produce a valid jpg file, it must save the data as expected for the format.
So you should be able to open it like any other jpeg file ?

@PowerNow Can you please explain what data you mean? It is really unclear what you mean and what your use case is...
@jsulm: The data are arbitrary strings. E.g. I saved them with
QImageWriter writer; writer.setFileName("...jpg"); writer.setText("key1", "Teststring1"); writer.setText("key2", "Teststring2"); ... writer.write(image);
In Qt everthing is fine!
Is it possible that they are SEPERATELY saved under the commend segment (FF FE COM Comments)?
For who is interrested: The strings saved via QImageWriter are placed seperately in the commend section of a .jpeg as ascii characters.
