convert an excel to image

Hi,

I have  a scenario where a user will be uploading an excel file to SharePoint and then we need to automate the process of converting the excel file with its maximum range to an image file and upload it to the same folder in the document library. How can we achieve this process?

Please help!!!

There are printer drivers who could export images instaed of really printing paper, i.e. these:

http://sourceforge.net/projects/imageprinter/
http://code-industry.net/imageprinter.php

There are more when you ask Google for "printer diver image". When you equip your excel files with some kind of onLoad-Macro, or generate some.NET code that does Excel remote control, you'd be able to print the table automatically to an image ... for upload, you might use some command line FTP client ....

Please create a event receiver for the document library you are using.
Create a Item added event and try below code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using xls = Microsoft.Office.Interop.Excel;
using System.IO;
using System.Windows.Forms;

namespace PracticeConsoleApp
{
    class Program
    {
        [STAThread]
        static void Main(string[] args)
        {
            string fileNameToProcess = @"C:\Users\jagtaram\Desktop\Office\App_n_Services.xls";

            //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(@"C:\Users\jagtaram\Desktop\Office\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;
        }
       
    }
}
