Devexpress SpreadSheet 如何在工作表中插入图片

基于文件流法：

workbook.BeginUpdate();
// Set the measurement unit to Millimeter.
workbook.Unit = DevExpress.Office.DocumentUnit.Millimeter;
try
{
    Worksheet worksheet = workbook.Worksheets[0];
    // Insert a picture from a file so that its top left corner is in the specified cell.
    // By default the picture is named Picture 1.. Picture NN.
    worksheet.Pictures.AddPicture("Pictures\\x-docserver.png", worksheet.Cells["A1"]);
    // Insert a picture at 70 mm from the left, 40 mm from the top, 
    // and resize it to a width of 85 mm and a height of 25 mm, locking the aspect ratio.
    worksheet.Pictures.AddPicture("Pictures\\x-docserver.png", 70, 40, 85, 25, true);
    // Insert the picture to be removed.
    worksheet.Pictures.AddPicture("Pictures\\x-docserver.png", 0, 0);
    // Remove the last inserted picture.
    // Find the shape by its name. The method returns a collection of shapes with the same name.
    Picture picShape = worksheet.Pictures.GetPicturesByName("Picture 3")[0];
    picShape.Delete();
}
finally
{
    workbook.EndUpdate();
}

基于URL法：

string imageUri = "https://www.devexpress.com/Products/NET/Controls/WinForms/spreadsheet/i/winforms-spreadsheet-control.png";
// Create an image from Uri.
SpreadsheetImageSource imageSource = SpreadsheetImageSource.FromUri(imageUri, workbook);
// Set the measurement unit to point.
workbook.Unit = DevExpress.Office.DocumentUnit.Point;

workbook.BeginUpdate();
try
{
    Worksheet worksheet = workbook.Worksheets[0];
    // Insert a picture from the SpreadsheetImageSource at 100 pt from the left, 40 pt from the top, 
    // and resize it to a width of 300 pt and a height of 200 pt.
    worksheet.Pictures.AddPicture(imageSource, 100, 40, 300, 200);
}
finally
{
    workbook.EndUpdate();
}

如何修改：

workbook.Unit = DevExpress.Office.DocumentUnit.Millimeter;
workbook.BeginUpdate();
try
{
    Worksheet worksheet = workbook.Worksheets[0];
    // Insert pictures from the file.
    Picture pic = worksheet.Pictures.AddPicture("Pictures\\x-docserver.png", worksheet.Cells["A1"]);
    // Specify picture name and draw a border.
    pic.Name = "Logo";
    pic.AlternativeText = "Spreadsheet Logo";
    pic.BorderWidth = 1;
    pic.BorderColor = DevExpress.Utils.DXColor.Black;
    // Move a picture.
    pic.Move(20, 30);
    // Change picture behavior so it will move and size with underlying cells. 
    pic.Placement = Placement.MoveAndSize;
    worksheet.Rows[5].Height += 10;
    worksheet.Columns["D"].Width += 10;
    // Specify rotation angle.
    pic.Rotation = 30;
    // Add a hyperlink.
    pic.InsertHyperlink("http://www.devexpress.com/Products/NET/Document-Server/", true);
}
finally
{
    workbook.EndUpdate();
}
