本文主要介绍了关于利用python将图片转换成excel文档的相关内容，编写了一小段Python代码，将图片转为了Excel，纯属娱乐，下面这篇文章主要给大家介绍了关于利用python将图片转换成excel文档格式的相关资料，需要的朋友可以参考借鉴，下面来一起看看吧。
实现步骤
读取图像，获取图像每个像素点的RGB值；
根据每个像素点的RGB值设置excel每个方格的颜色值；
根据像素点的坐标，写入excel文件；
保存退出；
示例代码
from PIL import Imageimport numpy as npimport timeimport matplotlib.pyplot as pltimport xlsxwriterdef get_xy(row, col): table = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ' num1 = col / 26 num2 = col % 26 # print num1, num2 if num1 == 0: return table[num2 - 1] + str(row) else: return table[num1-1] + table[num2 - 1] + str(row)def main(): img = np.array(Image.open('whale.jpeg')) # plt.figure("whale") # plt.imshow(img) # plt.show() rows, cols, dims = img.shape print img.shape print img.dtype print img.size print type(img) # print img[188, 188, 0] excel = xlsxwriter.Workbook('image_excel.xlsx') cellformat = excel.add_format({'bg_color': '#123456', 'font_color': '#654321'}) worksheet1 = excel.add_worksheet() data = [] color = [''] * cols cellcolor = "" for i in range(rows): for j in range(cols): # print hex(img[i, j, 0]), hex(img[i, j, 1]), hex(img[i, j, 2]) cellcolor = (hex(img[i, j, 0]) + hex(img[i, j, 1]) + hex(img[i, j, 2])).replace('0x', '') # print cellcolor cellformat = excel.add_format({'bg_color': '#'+cellcolor, 'font_color': '#'+cellcolor}) # cellformat = excel.add_format({'bg_color': '#C6EFCE', # 'font_color': '#006100'}) worksheet1.conditional_format(get_xy(i, j), {'type': 'cell', 'criteria': '<', 'value': 50, 'format': cellformat}) # data.append(data_row) excel.close() if __name__ == '__main__': main() # print get_xy(133, 27)
