Q:

What constants (codes) are available in opencv

When calling Opencv function, usually a constant is provided to function call, like:
im_hsv = cv2.cvtColor(im, cv2.COLOR_BGR2HSV)

while I can't find reference to all available constants. Opencv distribution download (~250MB) doesn't contain constants.h file.
Google shows this pointer: https://code.ros.org/trac/opencv/browser/trunk/opencv/interfaces/swig/filtered/constants.h?rev=277 which is deprecated as 8 years old.  
In Opencv project at Github , there doesn't seem to be such file also, so does anyone have a link to a file that contains all available Opencv constants?

Is this what you're looking for?
