Render the Worksheet and Workbook to Image using ImageOrPrintOptions
Sometimes, you might require presenting your worksheets as a pictorial representation. You do need to present the worksheet images into 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.
The SheetRender class handles the task of rendering images for the worksheet whereas the WorkbookRender does the same for a workbook. Both aforesaid classes have several overloaded versions of the toImage method that can directly convert a worksheet or a workbook to image file(s) specified with your desired attributes or options. You can save the image file to the disk/stream. There are several image formats supported, e.g BMP, PNG, GIFF, JPEG, TIFF, EMF, and so on.
