Black image when converting PDF to TIFF


You will find attached a PDF that we are converting to TIFF and the resulting TIFF file.

The TIFF file is completely black, except for the logo.

We are using Aspose.Pdf

Here is the code for the conversion:

Aspose.Pdf.Document pdfDocument = new Aspose.Pdf.Document(StreamHelper.WriteToStream(bytes));

// TIFF Settings

TiffSettings tiffSettings = new TiffSettings();

tiffSettings.Compression = compression; // CCITT4

tiffSettings.Depth = colorDepth; //Format1bpp

tiffSettings.SkipBlankPages = false;

// Resolution

Resolution r = new Resolution(resolution); //400

// TIFF device

TiffDevice tiffDevice = new TiffDevice(r, tiffSettings);


using (MemoryStream outputStream = new MemoryStream())


tiffDevice.Process(pdfDocument, outputStream);


return StreamHelper.ReadStreamFromBeginning(outputStream);
