In our case, we are asking Matplotlib library to set the following properties to our text fonts: So with these properties set, we have finally defined the text that we wanted on our canvas. In previous articles you saw a general overview on using the integrable webcam on Raspberry board: the PiCamera. So with this, we can finally get our captioned image file as shown below: So this was a brief tutorial on how to use Python to add text over an image programatically using Matplotlib library. Python and the OpenCV library make it very easy to work with visual input such as images or videos. Templates let you quickly answer FAQs or store snippets for re-use. Matplotlib is a Python data visualization library that is often used to plot graphs and charts to represent a dataset in a meaningful way. So for now we will further move on with our code. With the image being available, its time to start editing it using Matplotlib library. We need to use this module to import the image file (butterfly.jpg) into our program. These numbers are 0 to 255 for color channels. Therefore when we pass the values (12,8) to this parameter, we are specifying these exact values. CSS image overlays are a common technique for transposing text or images over each other. To save the image onto a new file, Matplotlib provides us with yet another function called savefig().

Following this, we will ask Matplotlib library to draw our picture onto the figure‘s canvas by calling imshow fuction as follows: As a result of the above code, Matplotlib will draw to image onto our figure object. This image would be used for overlay. However, it must be noted that it only draws the image to our figure object. So this is achieved by using the following piece of code: We will then go ahead with importing the butterfly.jpg file into our program using the line: The Image.open() method will open our file, read its content and store it into the variable img. One thing not mentioned in other answers is checking the text size. I hope you understand the idea. 2 Replies. What does this line even mean?
