How to build a QIODevice from Python IO object

[ejm1]

Hello,

I have a class that implements the RawIO class in Python. I would like to write a QImage into this stream. I do not think its possible to directly write a QImage without manually pulling out the raw values so I was wondering if there is some way to build some kind of Qt object around this IO. The code I want to do is below but in Python and with a buffer from Python not Qt. Any help would be appreciated, thanks!

QImage image;
QByteArray ba;
QBuffer buffer(&ba);
buffer.open(QIODevice::WriteOnly);
image.save(&buffer, "PNG"); // writes image into ba in PNG format

Hi,

One starting point is to create a QIODevice subclass that has a RawIO object as class member and then re-implement the writeData method to write into that object.

Hope it helps
