Articulus hic singillatim introducebit quomodo Pythone utatur ad imaginibus in Praecedo operandis, inclusis 4 sequentibus exemplis fundamentalibus;

Primum opus est ut tertiam partem bibliothecae Pythonis instituas - Spire.XLS pro Pythone . Productum detrahere potes et ex itinere locali instituere, vel sequenti pituita directo imperio uti, ut illud instituas:

# 创建Workbook对象
workbook = Workbook()

# 获取第一张工作表
sheet = workbook.Worksheets[0]

# 在指定单元格中插入图片（此处为第一行第二列，即B1单元格）
picture = sheet.Pictures.Add(1, 2, "示例.png")

# 设置图片宽高度
picture.Width = 120

Sample signum:

from spire.xls import *
from spire.xls.common import *

# 加载Excel文档
workbook = Workbook()
workbook.LoadFromFile ("插入图片.xlsx")

# 获取第一张工作表
sheet = workbook.Worksheets[0]

# 获取工作表中第一张图片
excelPicture = sheet.Pictures[0]
            
# 替换图片
excelPicture.Picture = Image.FromFile("pic.jpg")

# 保存文档
workbook.SaveToFile("替换图片.xlsx", ExcelVersion.Version2016)
workbook.Dispose()

Python imaginibus extractum ex Excel

De Spire.XLS in bibliotheca Pythonis etiam picturas in Excel documentis legere potest et eas ad certum fasciculi iter conservare. Perge sic:

1. Praecedo lima onerant et certa officina consequantur;
2. Iterate per omnes imagines in officina;
3. translatioExcelPicture.Picture.Save()Methodus extrahendi imagines ab Excel.

Sample signum:

from spire.xls import *
from spire.xls.common import *

# 加载Excel文档
workbook = Workbook()
workbook.LoadFromFile("图标.xlsx")

# 获取第一张工作表
sheet = workbook.Worksheets[0]

# 获取工作表中所有图片
for i in range(sheet.Pictures.Count - 1, -1, -1):
    pic = sheet.Pictures[i]

    # 保存图片
    pic.Picture.Save("提取图片\图片-{0:d}.png".format(i), ImageFormat.get_Png())
