Description
In RadSpreadsheet for WinForms, you may need to convert a FloatingChartShape to a bitmap image. Unlike RadChartView which offers a direct DrawToBitMap() method, FloatingChartShape requires a different approach for exporting to a bitmap.
Solution
To export a FloatingChartShape from a RadSpreadsheet to a bitmap, utilize the ChartModelToImageConverter.GetImageFromFloatingChartShape() method. This method accepts the FloatingChartShape as its first parameter and the desired image size as its second parameter. It returns an Image object, which you can then save to a file in PNG format or any other supported format.
Below is an example code snippet that demonstrates how to achieve this:
private void ExportChartToImage()
{
var worksheet = this.radSpreadsheet1.Workbook.Sheets[0] as Worksheet;
var image = Telerik.WinForms.Controls.Spreadsheet.Layers.ChartModelToImageConverter.GetImageFromFloatingChartShape(worksheet.Charts[0], new Size(780, 588));
image.Save("Chart.png", System.Drawing.Imaging.ImageFormat.Png);
}
In this example, the ExportChartToImage method retrieves the first chart from the worksheet, converts it to an image with the specified size, and then saves the image as a PNG file named "Chart.png".
