之前看到过很多头条，说哪国某人坚持了多少年自学使用excel画画，效果十分惊艳。对于他们的耐心我十分敬佩。但是作为一个程序员，自然也得挑战一下自己。这种需求，我们十分钟就可以完成！ mona-lisa 基本思路实现这个需求的基本思路是读取这张图片每一个像素的色彩值，然后给excel里的每一个单元格填充上颜色。所以主要用到的是 PIL 、 openpyxl 这两个库。 PIL使用 PIL 是Python里面做图像处理的时候十分常用的一个库，功能也是十分的强大，这里只需要用到 PIL 里一小部分的功能。 from PIL import Image img = Image.open(img_path) # 读取图片 width, height = img.size # 获取图片大小 r, g, b = img.getpixel((w - 1, h - 1)) # 获取像素色彩值 Image.open() 是PIL里面打开一张图片的函数，支持多种图片类型 img_path 是图片路径，可以是相对路径，也可以是绝对路径 img.size 是获取图片的 size 属性，包含图片的宽和高 img.getpixel() 是获取图片色彩值的函数，需传入一个 tuple 或 list ，值为像素坐标 xy openpyxl使用 openpyxl

I can set their values to None, but they still exist as empty cells. worksheet.garbage_collect() throws an error saying that it's deprecated. I'm using the most recent version of openpyxl. Is there any way of just deleting an empty cell (as one would do in Excel), or do I have to manually shift all the cells up? Thanks. 回答1: In

问题 I'm attempting to replicate and automate a well used practice in work: I'm trying to place multiple images and text within a cell in openpyxl, however I can only anchor images to the top left of a cell, and have not found a way to position any more accurately than that. So they end up overlapping with eachother and the text. from openpyxl import Workbook from openpyxl.drawing.image import Image wb = Workbook() ws = wb.active img = Image('image.png') ws.add_image(img, 'B2') # img.anchor is now
