add text overlay to image? #5

Open Obliterous opened 6 years ago

Obliterous commented 6 years ago

Is it possible to add text overlay & timestamp to image/video so that multiple similar streams can be distinguished?

cvsandbox commented 6 years ago

This functionality is not there. Need to add it.

It should be quite simple using opencv.The documentation for the specific function you need to use can be found here: https://docs.opencv.org/master/d6/d0f/structcv_1_1gapi_1_1wip_1_1draw_1_1Text.html#details

Some example code:

putText( image2, "OpenCV forever!", org, FONT_HERSHEY_COMPLEX, 3,Scalar(i, i, 255), 5,lineType );

It is taken from here: https://docs.opencv.org/master/de/d06/samples_2cpp_2tutorial_code_2ImgProc_2basic_drawing_2Drawing_2_8cpp-example.html#a22

Windows version already has this feature: https://github.com/cvsandbox/cam2web/commit/b915c73a55dc281ab3b68cdb2fae032fa2ef048a

No OpenCV needed.
