Can QPicture scale and rotate ?

[igor]

The documentation shows how a QPicture can be "painted" repeatedly at different locations, but I would like to know if I can scale and/or rotate it as well ? :confused:

Are there any examples that demonstrate this ?

Thanks. :D

The documentation also says that you have to use QPixmap if you want to modify a image :)

I think you misunderstand the question.

The docs say,
The QPicture class is a paint device that records and replays QPainter commands.

OK, so then let me define a QPicture that draws a square.
Next, I play the QPicture onto the current QPainter.
Next, I use the QPainter's scale method to double the scale and rotate method to turn things 45 degrees clockwise
Now, can I "play" my QPicture again and get a double-size, rotated square ?

You can rotate/scale the painter before drawing the picture on it.

You can rotate/scale the painter before drawing the picture on it.

So then the example I roughed out would work ? :o

[wysota]

Yes, it will work.

Oh ok, sorry :)
