hi @mannanfazil

I am using Aspose.Words for .NET

my requirement is I want to graysacle or black and white whole word document.

Aspose.Words.Saving.OoxmlSaveOptions options = new Aspose.Words.Saving.OoxmlSaveOptions();
options.ColorMode= Aspose.Words.Saving.ColorMode.Grayscale;

is makinhg no difference

so can you please suggest me correct way to acheive this


Thanks for your inquiry. The SaveOptions.ColorMode property is useful when saving the document to fixed page formats such as .pdf, .xps, images. If you want to save document in .pdf format then use this sample code to achieve results.

Document doc = new Document(MyDir + "input.docx");
PdfSaveOptions pdfSaveOptions = new PdfSaveOptions();
pdfSaveOptions.ColorMode = ColorMode.Grayscale;
doc.Save(MyDir + "output.pdf", pdfSaveOptions);

If you want to save document in .docx format then please use the following code:

        Document doc = new Document(MyDir + "input.docx");
        NodeCollection runs = doc.GetChildNodes(NodeType.Run, true);
        // Set color of text in each run.
        foreach (Run run in runs)
            run.Font.Color = Color.Black;

        foreach (Words.Drawing.Shape shape in doc.GetChildNodes(NodeType.Shape, true))
            if (shape.HasImage)
                shape.ImageData.GrayScale = true;


        doc.Save(MyDir + "output.docx");     

Hope, this helps.
