Syntax and Hints for Processing

I am new to Processing3, I am facing issues in finding the syntax of different commands in processing. e.g contour.

Can someone guide me how i can simply check if my contours are convex.
precisely how to use cv.isContourConvex() function

hi @abubakar have you tried pressing the key combination, Ctrl-Space?, the code completion dropdown menu should appear. So in your case, you would start typing ‘begin’ then if you press the key combination, the beginContour() command will be listed.

And once you create a function, isContourConvex(), the function will be listed in the code completion menu once you type cv.

Hope this helps.

I will look up their documentation. You can find it here: ok… it is just few clicks away.
