Export GraphicsView contents as JPG

[Terabyte]

Hi, the following code doesn't seem to work, it should take a 'screenshot' of the contents of the whole of the QGraphicsView. For some reason it doesn't. The contents of the saved file is blank (open in notepad, no data at all).
If I change JPG to BMP it works, but the image is inverted. (black white white black)
Anybody know what I'm doing wrong?

What does:

qDebug() << QImageWriter::supportedImageFormats();

qDebug() << QImageWriter::supportedImageFormats();

To copy to clipboard, switch view to plain text mode 

output?

I had, I think, a related problem with JPG files. (As suggested also by jpn's response) ...

QImageWriter supportedImageFormats only sometimes includes JPEG. Why?

In particular, the problem is addressed within this FAQ:

You probably didn't deploy image plugins with your application. You need to copy the contents of plugins/imageformats directory of your Qt installation to the imageformats subdirectory of the directory where you deployed the application binary.

For instance if you deployed the application to C:\Program Files\MyApp, you need to copy the plugins to C:\Program Files\MyApp\imageformats.

Imageformat plugins are libraries called "qjpeg", "qsvg", "qtiff", etc.
