Calculate the length of a string in pixels in openCV

c++, drawing, image, opencv, size

Solution

You're looking for getTextSize.

Problem

Does anybody know any functions that `openCV` has or any methods to get the length of a string in pixels? For example, I have string c = "Hello" and I use it to draw to an image by `cvPutText`. How can I get the numbers of pixels of that string in that image the string occupied?
