Converting Excel, PowerPoint, PDF, and Word to Images in .NET using Aspose

so I am looking for a way to convert Excel, PowerPoint, PDF, and Word to Images. I was wondering if anyone has experience with the Aspose suite and knows if all of this can be done with the Aspose.PDF suite, or would I need to get Aspose.slides, and Aspose.word as well?

I know it's 2019, but if anyone is still wondering, you can do this using Aspose.Words.

The following values (and more) in the SaveFormat enum are available:

    Tiff = 100,
    //
    // Summary:
    //     Renders a page of the document and saves it as a PNG file.
    Png = 101,
    //
    // Summary:
    //     Renders a page of the document and saves it as a BMP file.
    Bmp = 102,
    //
    // Summary:
    //     Renders a page of the document and saves it as a JPEG file.
    Jpeg = 104,
    //
    // Summary:
    //     Renders a page of the document and saves it as a GIF file.
    Gif = 105

You would use them like so:

    var fileContents = asposeDocument.GenerateDocument(Aspose.Words.SaveFormat.Png);

Conversion from office document to image could be done without using any third party component. Below code will convert specific range from an Excel worksheet to Image, for example.

IMPORTANT: Don't forget to mark the method with [STAThread] attribute.

Usings:

    using xls = Microsoft.Office.Interop.Excel;
    using System.IO;
    using System.Windows.Forms;

Conversion Code:

    [STAThread]
    static void Main(string[] args)
    {
        string fileNameToProcess = @"D:\Book2.xlsx";

        //Start Excel and create a new document.
        xls.Application oExcel = new xls.Application();
        xls.Workbook wb = null;
        try
        {
            wb = oExcel.Workbooks.Open(
                fileNameToProcess.ToString(), false, false, Type.Missing, "", "", true, xls.XlPlatform.xlWindows, "", false, false, 0, false, true, 0);
            //wb.RefreshAll();

            xls.Sheets sheets = wb.Worksheets as xls.Sheets;
            xls.Worksheet sheet = sheets[1];

            //Following is used to find range with data
            string startRange = "A1";
            string endRange = "P25";
            xls.Range range = sheet.get_Range(startRange, endRange);
            range.CopyPicture(xls.XlPictureAppearance.xlScreen, xls.XlCopyPictureFormat.xlBitmap);

            System.Drawing.Image imgRange = GetImageFromClipboard();

            imgRange.Save(@"d:\ExcelSheetImage.bmp", System.Drawing.Imaging.ImageFormat.Bmp);

            wb.Save();
            Console.Write("Specified range converted to image successfully. Press Enter to continue.");
        }
        catch (Exception e)
        {
            Console.WriteLine(e.Message);
            //throw;
        }
        finally 
        {
            wb.Close();
            oExcel.Quit();
            oExcel = null;
        }

        Console.ReadLine();
    }

    public static System.Drawing.Image GetImageFromClipboard()
    {
        System.Drawing.Image returnImage = null;

        // This doesn't work
        //if (Clipboard.ContainsImage())
        //{
        //    returnImage = Clipboard.GetImage();
        //}
        //return returnImage;

        // This works
        System.Windows.Forms.IDataObject d = Clipboard.GetDataObject();
        if (d.GetDataPresent(DataFormats.Bitmap))
        {
            returnImage = Clipboard.GetImage();
        }

        return returnImage;
    }
