Hi there,

I've been researching how to use Telerik PDFProcessing to Digitally Sign a PDF. But can't find any documentation on how to incorporate it into ASP.Net AJAX (VB).

When the indirect object contains more spaces between the object number and the generation number the object content is not successfully parsed.

Expected: one space

Actual: more than one space

When using an ImageSharp version bigger than 2.0 an exception is thrown: "MissingMethodException: 'Method not found: 'SixLabors.ImageSharp.Image SixLabors.ImageSharp.Image.Load(Byte[], SixLabors.ImageSharp.Formats.IImageFormat ByRef)'."

Workaround: Downgrade to a lower ImageSharp version or use a custom implementation of ImagePropertiesResolverBase/JpegImageConverter.

Setting a filter on a mask results in an invalid file when exporting. 

Workaround: Set the filer like this:

PdfFormatProvider provider = new PdfFormatProvider();
provider.ExportSettings.ImageCompression = new ImageFilterTypes[] { ImageFilterTypes.FlateDecode };

InvalidOperationException Cannot find the "endstream" keyword with a specific file.

According to the PDF Specification:

A stream consists of a dictionary followed by zero or more bytes bracketed between the keywords stream and endstream:

dictionary
stream
… Zero or more bytes …
endstream
