oehm, jarp, I expect it to draw into the image. Puh, good to know that it is only good for drawing onto the window :-(

Is there no way in opencv to write unicode text into an image? (Like putText() does it but with unicode characters)

Hi,

I built opencv with QT support since the character set of putText() is too limited for my needs (need French accents and German umlaute).

When I use AddText() with a fontQT, i get an error, since cvAddText() of window_QT.cpp expects guiMainThread to be set. However, I only do image computations and add text, so I don't want to show the image. Followingly, I do not need a NamedWindow which would set guiMainThread.

Is there a way to use addText() on images without setting guiMainThread aka displaying them?
