本文将介绍如何使用Spire.XLS for .NET转换Excel中的形状和SmartArt图形到图片。

原Excel文档：

using Spire.Xls;
using System.Collections.Generic;
using System.Drawing;
using System.Drawing.Imaging;

namespace Convert_Shapes_and_SmartArt_to_Image
{
    class Program
    {
        static void Main(string[] args)
        {
            //创建Workbook对象
            Workbook workbook = new Workbook();
            //加载Excel文档
            workbook.LoadFromFile("Sample.xlsx");

            //获取第一个工作表
            Worksheet sheet = workbook.Worksheets[0];

            //创建SaveShapeTypeOption对象
            SaveShapeTypeOption shapelist = new SaveShapeTypeOption();
            //保存工作表中的形状和SmartArt图形到图片
            List images = sheet.SaveShapesToImage(shapelist);

            //保存图片到指定路径
            int index = 0;
            foreach (Image img in images)
            {
                img.Save("Image/" + "toImage" + index + ".Png", ImageFormat.Png);
                index++;
            }
        }
    }
}

Imports Spire.Xls
Imports System.Collections.Generic
Imports System.Drawing.Imaging

Namespace Convert_Shapes_and_SmartArt_to_Image
    Friend Class Program
        Private Shared Sub Main(ByVal args As String())
            '创建Workbook对象 Dim workbook As Workbook = New Workbook() '加载Excel文档
            workbook.LoadFromFile("Sample.xlsx")

            '获取第一个工作表 Dim sheet As Worksheet = workbook.Worksheets(0) '创建SaveShapeTypeOption对象
            Dim shapelist As SaveShapeTypeOption = New SaveShapeTypeOption()
            '保存工作表中的形状和SmartArt图形到图片 Dim images As List(Of Bitmap) = sheet.SaveShapesToImage(shapelist) '保存图片到指定路径
            Dim index As Integer = 0

            For Each img As Image In images
                img.Save("Image/" & "toImage" & index & ".Png", ImageFormat.Png)
                index += 1
            Next
        End Sub
    End Class
End Namespace

转换结果：
