Hi,

I am a representative of Aspose.Cells, I would help you regarding converting Excel worksheets to Tiff images. I think you may try to use PageSetup features for your desired printing options. Moreover, you may also use ImageOrPrintOptions attributes according to your needs.

See the sample code below for your reference.

Sample code:

Aspose.Cells.Workbook workbook = new Aspose.Cells.Workbook(“e:\test2\MyFile.xlsx”, new Aspose.Cells.LoadOptions(Aspose.Cells.LoadFormat.Xlsx));

Aspose.Cells.Worksheet sheet = workbook.Worksheets[0];

//Apply Excel’s PageSetup features

//Print all the sheet

sheet.PageSetup.PrintArea = “”;

//Set Black and White mode

sheet.PageSetup.BlackAndWhite = true;

//Set the print quality

sheet.PageSetup.PrintQuality = 180;

//Set ImageOrPrintOptions

//Apply different Image and Print options

Aspose.Cells.Rendering.ImageOrPrintOptions options = new Aspose.Cells.Rendering.ImageOrPrintOptions();

//Set Horizontal Resolution

options.HorizontalResolution = 300;

//Set Vertical Resolution

options.VerticalResolution = 300;

//Set TiffCompression

options.TiffCompression = Aspose.Cells.Rendering.TiffCompression.CompressionLZW;

//Set Autofit options

options.IsCellAutoFit = false;

//Set Image Format

options.ImageFormat = System.Drawing.Imaging.ImageFormat.Tiff;

//Set printing page type

[//options.PrintingPage](https://options.printingpage/) = Aspose.Cells.PrintingPageType.Default;

[//options.OnePagePerSheet](https://options.onepagepersheet/) = true;

//Render the sheet with respect to specified image/print options

Aspose.Cells.Rendering.SheetRender sr = new Aspose.Cells.Rendering.SheetRender(sheet, options);

//Render/save the image for the sheet

for (int i = 0; i < sr.PageCount; i++)

{

sr.ToImage(i, “e:\test2\test_image_” + sheet.CodeName + “_” + i + “.tif”);

}

Also, see the documents for your complete reference:

Thank you.

Hi Dhivya,

You can use Aspose.Pdf for .NET to convert PDF files to TIFF images. You can also specify different settings using TiffSettings class, including color depth and compression, while saving the PDF as TIFF file. Please see the following topic for details and code sample:

I hope this helps. If you find any further questions, please do let us know.
