Python OpenCV | cv2.putText() method - GeeksforGeeks

28 Aug, 2019
OpenCV-Python is a library of Python bindings designed to solve computer vision problems. cv2.putText() method is used to draw a text string on any image.
Syntax: cv2.putText(image, text, org, font, fontScale, color[, thickness[, lineType[, bottomLeftOrigin]]])
Parameters:image: It is the image on which text is to be drawn.text: Text string to be drawn.org: It is the coordinates of the bottom-left corner of the text string in the image. The coordinates are represented as tuples of two values i.e. (X coordinate value, Y coordinate value).font: It denotes the font type. Some of font types are FONT_HERSHEY_SIMPLEX, FONT_HERSHEY_PLAIN, , etc.fontScale: Font scale factor that is multiplied by the font-specific base size.color: It is the color of text string to be drawn. For BGR, we pass a tuple. eg: (255, 0, 0) for blue color.thickness: It is the thickness of the line in px.lineType: This is an optional parameter.It gives the type of the line to be used.bottomLeftOrigin: This is an optional parameter. When it is true, the image data origin is at the bottom-left corner. Otherwise, it is at the top-left corner.
Return Value: It returns an image.
