如何在python3中使用graphics.py获取和设置像素的颜色值

Question

I'm implementing Boundary Fill Algorithm for polygons in python.How to get and set the color of a pixel? I'm using graphics.py file.

Answer 1

Zelle graphics provides operators to manipulate pixels of images as documented in the code:

The library also provides a very simple class for pixel-based image manipulation, Pixmap. A pixmap can be loaded from a file and displayed using an Image object. Both getPixel and setPixel methods are provided for manipulating the image.

But not higher level objects like polygons.

This answer to Get color of coordinate of figure drawn with Python Zelle graphics shows how to get the fill color of an object like a polygon located at a given (x, y) coordinate using the tkinter underpinnings of Zelle graphics. I doubt this technique can be used to set the color of a pixel of a polygon, however.
