The attached Excel files contain Barcode images (Issue271…xls) - which are rendered as imgae / tif using Aspose cells - however the generated image contains a number that shouldn’t appear - please llok at the goodImage.tif file to see the desired ouput (this was generated using MS Fax printer).

@SamManoff,

Thanks for the template file and image files.

After an initial test, I am able to reproduce the issue as you mentioned by using the following sample code with your template files. I found an issue with barcode images in Sheet to TIFF rendering, the generated image contains a number on barcode that should not appear:
e.g
Sample code:

Workbook book = new Workbook("e:\\test2\\Issue271_1.xls");

            //Define ImageOrPrintOptions
            var options = new ImageOrPrintOptions
            {
                SaveFormat = SaveFormat.TIFF,
                HorizontalResolution = 200,
                VerticalResolution = 200,
                TiffCompression = TiffCompression.CompressionCCITT4
            };

            var i = 0;
            foreach (Worksheet sheet in book.Worksheets)
            {
                if (sheet.IsVisible)
                {
                    //Render the sheet with respect to specified image/print options
                    SheetRender sr = new SheetRender(sheet, options);
                    //Render the image for the sheet
                    using (var imageStream = new MemoryStream())
                    {
                        sr.ToImage(i, imageStream);
                        imageStream.Seek(0, SeekOrigin.Begin);
                        var img = System.Drawing.Image.FromStream(imageStream);
                        img.Save("e:\\test2\\out1image" + i.ToString() + ".tif", ImageFormat.Tiff);
                        i++;
                    }
                }
            }

Thanks Amjad.
The problem is not restricted to Tiff output any image format seems to emit a weird number.
Please keep me updated on possible resolution.

Regards Sam.
