Hi

Thanks for your request. Sure, you can convert text documents to images using Aspose.Words. Here you can find a code that shows how you can load TXT documents into Document object:

http://www.aspose.com/documentation/.net-components/aspose.words-for-.net/howto-load-plain-text-txt-files.html

Then, you can convert the Document to PNG and make it grayscale:

http://www.aspose.com/documentation/.net-components/aspose.words-for-.net/aspose.words.saving.imagesaveoptions.imagecolormode.html

Code will look like the following:

[Test]

public void Test001()

{

    TxtToGrayScalePng(@"Test001\in.txt", @"Test001\");

}

/// <summary>

/// Converts txt document to png images.

/// </summary>

private static void TxtToGrayScalePng(string inputFileName, string outputDirectory)

{

    // Load TXT document into Document object.

    // This object will help us generate the document.

    DocumentBuilder builder = new DocumentBuilder();

    // You might need to specify a different encoding depending on your plain text files.

    using (StreamReader reader = new StreamReader(inputFileName, Encoding.UTF8))

    {

        // Read plain text "lines" and convert them into paragraphs in the document.

        string line = null;

        while ((line = reader.ReadLine()) != null)

        {

            builder.Writeln(line);

        }

    }

    // Save each page of the document as grayscale PNG.

    ImageSaveOptions opt = new ImageSaveOptions(SaveFormat.Png);

    opt.PageCount = 1;

    opt.ImageColorMode = ImageColorMode.Grayscale;

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

    {

        opt.PageIndex = i;

        string outputFileName = string.Format("page_{0}.png", i);

        builder.Document.Save(Path.Combine(outputDirectory, outputFileName), opt);

    }

}

You can use code suggested here you insert your existing images into Document object:

http://www.aspose.com/documentation/.net-components/aspose.words-for-.net/howto-convert-an-image-to-pdf.html

And save the document’s pages as grayscale PNG as shown in the previous code example.

Hope this helps.

Best regards,
