Hi,

the following code produces a window, that is a little bit to large for my taste. How can I set the size of an window (in px or something like that)?

you can resize it ( manually ) if you do:

namedWindow("window",CV_WINDOW_NORMAL);

the default param here is CV_WINDOW_AUTOSIZE, which does not allow resizing

on win & linux it will remember the size for that windowname, even

Simply put, use the functionality provided by the C++ cv::Mat class interface :)

Mat inputImage = imread(location);
Mat window = inputImage( Rect(xWindowUpperLeft, yWindowUpperLeft, widthWindow, heigthWindow) );

Thanks, the Parameter CV_WINDOW_NORMAL has done the trick, works fine.

Ciao, Andre
