Tomaz,

I just had a quick attempt to implement that but I have to admit, I don’t know enough C++ for this. Maybe you can help me out.

We have the class SHashedImage with is a pimped version of QImage defined in divepicturewidget.cpp

It gets a struct * picture as an argument and tries to load the image, first from the file name and if that fails from hash lookup.

My idea was to extend this such that when loading from a filename as a QImage fails (isNull() is true), we could try to load the file as a QMove and then extract a Image via

		QMovie film(QString(picture->filename));
		if (film.isValid()) {
			film.currentImage()

(Maybe the first image is not ideal, we could seek forward a bit).

But how to I tell C++ to set the QImage inside SHashedImage to this? Going via loadFromData seems to be somewhat roundabout.

Can you help me?

Best
Robert
