Get text size using opencv python
You can first use a text detector or a contour detector to get the height of one line of text. That can be used to get the size of text in pixels. But after that, you need some reference to convert it to font size (which is usually defined in points). 
All of this can be done in OpenCV. If you post an image with text, some of us will be able to provide more detailed answers.
im trying to get the font size of text in an image, is there any library in python or can it be done using opencv? Thanks in advance
