Converting Worksheet to Image using ImageOrPrint Options with Golang via C++
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, insert them into a Word document, a PDF file, a PowerPoint presentation, or use them in some other scenario. Simply put, 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. Additionally, Aspose.Cells supports setting different options like image format, resolution (both vertical and horizontal), image quality, and other image and print options.
You might consider Office Automation, but it has its own drawbacks. There are several reasons and issues involved, such as 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, perform the conversion of a worksheet to an image using a few simple lines of code with different image and print options using Aspose.Cells API.
You need to include the Aspose.Cells.Rendering namespace in 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 for the worksheet. 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 bitmap object, and you can save an image file to the disk/stream. Several image formats are supported, such as BMP, PNG, GIF, JPEG, TIFF, EMF, and so on.
