Untitled Reusable Block

//Create a new workbook.

Aspose.Cells.Workbook workbook = new Aspose.Cells.Workbook();

//Open the existing excel file which contains the pie chart.

workbook.Open(“d:\\piechart.xls”);

//Get the designer chart (first chart) in the first worksheet.

//of the workbook.

Chart chart = workbook.Worksheets[0].Charts[0];

//Convert the chart to an image file.

System.Drawing.Bitmap bitmap = chart.ToImage();

//Save the chart image (jpg) file to disk.

bitmap.Save(@“d:\PieChart.jpg”,System.Drawing.Imaging.ImageFormat.Jpeg);

Additionally I write its parallel VB.NET code here for your convenience:

‘Create a new workbook.

Dim workbook As Aspose.Cells.Workbook = New Aspose.Cells.Workbook()

‘Open the existing excel file which contains the pie chart.

workbook.Open(“d:\piechart.xls”);

‘Get the designer chart (first chart) in the first worksheet.

‘of the workbook.

Dim chart As Chart = workbook.Worksheets(0).Charts(0)

‘Convert the chart to an image file.

Dim bitmap As System.Drawing.Bitmap = chart.ToImage()

‘Save the chart image (jpg) file to disk.

bitmap.Save(“d:\PieChart.jpg”,System.Drawing.Imaging.ImageFormat.Jpeg)
