Create field to accept mouse drawings and convert it to an image

Question

I want to create a field in python that will accept mouse drawings and convert it into 28x28 pixels image:

field like this

I want to use this image result to predict the output using a model that i have already trained, the model is of hand writing recognition where each image is of 28x28 pixels

This looks like a good start... https://stackoverflow.com/a/40617081/2836621 — Mark Setchell, Jun 10 '18 at 10:12

You can use Tkinter along with PIL (Python Imaging Library) to perform your task.

I came across THIS QUESTION which solves the problem of saving drawings on a canvas as an image.

I modified the existing code to resize the image to dimension of 28 x 28 and saved the result.

Follow the code in the link and in the save() just the resize() function before saving the image:

def save(self):
    filename = "C:/Users/Desktop/my_drawing.jpg"
    self.image = self.image.resize((28, 28), 1)
    self.image.save(filename)

@MarkSetchell It took me some time and I didn't know I had Tkinter built-in. It was really exciting to try out something new! – Jeru Luke Jun 10 '18 at 12:20
The result that I am getting is not quite good, I have read about html canvas tag but for that i have to make an entire page, so how can i make it good – Hrishikesh Vichore Jun 25 '18 at 17:21
