Converting Worksheet to Image using ImageOrPrint Options

Saving Worksheets to Images - Different Approaches

Sometimes, you might require presenting your worksheets as a pictorial representation. You may need to present the worksheet images in your applications or web pages. You might need to insert the images into a Word document, a PDF file, a PowerPoint presentation, or use them in some other scenario. Simply, you want a worksheet rendered as an image so that you can use it elsewhere. Aspose.Cells supports converting worksheets in Excel files to images. Also, Aspose.Cells supports setting different options like image format, resolution (both vertical and horizontal), image quality, and other image and print options.

You might try Office Automation, but it has its own drawbacks. There are several reasons and issues involved: for example, security, stability, scalability, speed, price, and features. In short, there are many reasons, with the top one being that Microsoft itself strongly recommends against Office automation from software solutions.

This article shows how to create a console application in Visual Studio .NET, and perform the conversion of a worksheet to an image using different image and print options with a few simple lines of code using the Aspose.Cells API.

You need to import the Aspose.Cells.Rendering namespace to your program/project. It has several valuable classes, for example, SheetRender, ImageOrPrintOptions, WorkbookRender, etc.

The Aspose.Cells.Rendering.SheetRender class represents a worksheet to render images. It has an overloaded ToImage method that can directly convert a worksheet to image file(s) specified with your desired attributes or options. It can return a System.Drawing.Bitmap object, and you can save an image file to disk or a stream. There are several image formats supported, e.g., BMP, PNG, GIF, JPEG, TIFF, EMF, and so on.

Creating a template workbook in Microsoft Excel

I created a new workbook in MS Excel and added some data to the first worksheet. Now, I will convert the template file’s worksheet “Sheet1” to an image file “SheetImage.tiff” and will apply different image options such as horizontal and vertical resolutions, TIFF compression, etc.

Download and Install Aspose.Cells

First, you need to download Aspose.Cells for .NET. Install it on your development computer. All Aspose components, when installed, work in evaluation mode. The evaluation mode has no time limit and it only injects watermarks into produced documents.

Create a Project

Start Visual Studio .NET and create a new console application. This example will show a C# console application, but you can use VB.NET too.

Add References

This project will use Aspose.Cells. So, you have to add a reference to the Aspose.Cells component in your project. For example, add a reference to …\Program Files\Aspose\Aspose.Cells for .NET\Bin\Net1.0\Aspose.Cells.dll
