You may have to find the shape of your specific text this using Paint or other application. The approximate shape of the text in the above example is (268, 36). If you know the shape (width, height) of the text you are writing on the image, then you can place at center aligned on the image. Input Image: sample.png Output Image: output.png Python – Write Text at the center of the image Following are the input and output images. We have written the output image to a file. In the above example, we have provided a sample image, and wrote some text on the image. position: distance along horizontal and vertical axis from top left corner of the image.Position, #position at which writing has to startĪs you can see from the above example, you can provide Image, #numpy array on which text is written
Image = cv2.imread('sample.png',cv2.IMREAD_UNCHANGED) The usage of putText() function is provided in the following example. Im_draw.To write text on image with OpenCV library of Python, use putText() method. # add some margin to avoid touching bordersīox_width = text_box - text_box - (2*MARGIN) While i < len(words) and (line_width + FONT.getsize(words)) < width_limit: # get text which can fit in one line, remains is list of words left over The function get_line returns the current line and remaining words, which can again be used in loop, as in draw_lines function below. But for most cases it should be OK.Ī minimal example, keep adding words until it exceeds the maximum width limit. It's probably not super-fast, because it renders whole text word by word, to determine words width.
