在图像上插入文本，python [英] insert text on image, python

问题描述

我的项目是关于加载图像，当我点击一个按钮时，图像中会出现一个文本区域，我可以在其上写一个文本，然后保存写在图像和图像上的文本。为此，我使用 tkinter ，但我将图像设置为背景，并添加了一个文本框（文本小部件）和输入文本，但显然我无法保存该图像（设置为背景）和写在其上的文本。我尝试使用 PIL 但我找不到我要找的东西。
这是我的代码，使用 tkinter ：

My project is about loading an image and when I click on a button, a text area appears in the image, and I can write a text on it and later on save the text written on the image and the image. To do so I used tkinter but I set my image as background and I added a text box(text widget) and enter a text, but obviously I can't save that image( the one set as background) and the text written on it. I tried using PIL but i didn't find what I was looking for. This is my code using tkinter :

from tkinter import *
from PIL import ImageTk
import cv2

#root = Tk()

image=cv2.imread("New_refImg.png")
width_1, height_1,channels = image.shape   
print(width_1)
print(height_1)

canvas = Canvas(width =height_1, height = width_1, bg = 'blue')
canvas.pack(expand = 1, fill = BOTH)

img = ImageTk.PhotoImage(file = "New_refImg.png")

canvas.create_image(0, 0, image = img, anchor = NW)

#Add text
entry = Entry(canvas, width=12)
entry.pack(side=BOTTOM,padx=43,pady=height_1-130) # "side" position button

def onok():    
    x= entry.get().split('x')
    print(x)

Button(canvas, text='OK', command=onok).pack(side=LEFT)

mainloop()

推荐答案

因此，您可以在画布中绘制文字 - Python：如何在画布中添加文本？​​ - 然后将该画布转换为图像以便保存 - 如何将画布内容转换为图像？

So, you could draw text into your canvas - Python: how to add text inside a canvas? - and then convert that canvas to an image for saving - How can I convert canvas content to an image?

但是，我建议使用PIL / Pillow。您可以在图像上绘制文本 - https://pillow.readthedocs.io/en/5.2.x/reference/ImageDraw.html#example-draw-partial-opacity-text 。您可以将Pillow图像直接作为参数提供给ImageTk.PhotoImage - ImageTk.PhotoImage（im）。您可以自然地将图像保存到文件中 - http://pillow.readthedocs.io/en/5.2.x/reference/Image.html#PIL.Image.Image.save

However, I would instead recommend using PIL/Pillow. You can draw text onto an image - https://pillow.readthedocs.io/en/5.2.x/reference/ImageDraw.html#example-draw-partial-opacity-text. You can provide the Pillow image to ImageTk.PhotoImage directly as an argument - ImageTk.PhotoImage(im). You can naturally save the image to a file - http://pillow.readthedocs.io/en/5.2.x/reference/Image.html#PIL.Image.Image.save
