Little hack to have an imshow function like OpenCV

OpenCV and Qt are graphically incompatible. Both require ownership and also hijack program's main thread.

This module brings the Qt version of cv2.imshow. To maximize compatibility with both cases, remove prefix:

from cv2 import imshow
from qtimshow import imshow

This module requires two parts to work:

• Attach to main thread (enable it)

import qtimshow

if __name__ == '__main__':
    ...
    app = QtGui.QApplication(sys.argv)
    qtimshow.enable()
    ....
    app.exec_()

• Import imshow function (use it)

from qtimshow import imshow

Image type handling is too limited. Supported:

• RGB
• Grayscale

Any further type can be manually supported by pass the Qt's counterpart type:

from PyQt4.QtGui import QImage
imshow('a title', img_rgb, QImage.Format_RGB888)

This module can be installed, added to pythonpath or just copied.

Recommended option:

mkdir -p $HOME/.python_modules
git clone https://github.com/varhub/qtimshow.git $HOME/.python_modules/qtimshow
export PYTHONPATH=$PYTHONPATH:$HOME/.python_modules
# you can add last line to .profile or .bashrc to avoid type it always
