I don’t see this in the documentation anywhere, so it probably doesn’t exist, but just in case:

I have a function that accepts as a parameter a vector of QImages. Each QImage was loaded from disk at some point and has not been edited–it is just read from. Ideally what I’d like to do is loop over all the QImages and output a list of their file paths to an XML file.

Unfortunately, I’m not seeing in the documentation any way to get at the original file path that the image was loaded from. So my question is, is it possible, given only a QImage, to figure out what file path the QImage was originally loaded from or not?

Something along the lines of:

QString QImage::getOriginalFilepath();

I know this is probably a futile question, but its always worth a shot to ask, I suppose.

(I’m using Qt 4.7, by the way.)

    I looked through the code, and that information doesn’t appear to be saved anywhere. QImage::load (and the constructor) uses QImageReader(fileName,format).read() and then copies the result to itself. The QImageReader is set to delete the device representation (the opened file object) as soon as it’s finished reading.

    So, in summary, it appears that this is not possible.
