When the image within a document is compressed with FlateDecode and there is no specific ImageFilterTypes set the image data is exported with FlateDecode compression but a wrong DCTDecode filter name is set which leads to a broken PDF file.

Workaround: Set explicitly the the ImageCompression filter:
PdfFormatProvider provider = new PdfFormatProvider();
provider.ExportSettings.ImageCompression = new ImageFilterTypes[] { ImageFilterTypes.FlateDecode };

When a document is exported with a cross-reference stream, the stream is missing the required according to the specification Length property. Although most of the viewers open the document without any issues, some cannot. Such documents cannot be opened in MS Edge.

When a document containing a SignatureField is exported with the IsEncrypted property set to true, a not set UserPassword is required to open it, which makes it impossible to be opened.

Workaround: Exporting with AES256 encryption does not have this problem:

provider.ExportSettings = new PdfExportSettings
{
	IsEncrypted = true,
	EncryptionType = EncryptionType.AES256
};

Trying to clone the Signature of a SignatureField leads to InvalidOperationException as the FieldName of the cloned signature is already set.

Workaround: Remove the signatures before the merging of the document:

private static void RemoveSignatures(RadFixedDocument document)
{
	List<FormField> signatures = document.AcroForm.FormFields.Where(ff => ff.FieldType == FormFieldType.Signature).ToList();
	if (signatures.Count > 0)
	{
		foreach (FormField signature in signatures)
		{
			document.AcroForm.FormFields.Remove(signature);
		}
	}

	List<SignatureWidget> signatureWidgets = document.Annotations.Where(a => a.Type == AnnotationType.Widget && a.GetType() == typeof(SignatureWidget)).Cast<SignatureWidget>().ToList();
	if (signatureWidgets.Count > 0)
	{
		foreach (var signatureWidget in signatureWidgets)
		{
			foreach (RadFixedPage page in document.Pages)
			{
				if (page.Annotations.Contains(signatureWidget))
				{
					page.Annotations.Remove(signatureWidget);
				}
			}
		}
	}
}

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

According to the PDF Specification:

dictionary
stream
… Zero or more bytes …
endstream

SpreadProcessing has a method,  cellValue.GetValueAsString(format), which allows the user to apply excel format on a value and get the result. While in SpreadStreamProcessing one could get the format and the value, there is no way to get their result and this is very inconvenient when the values in question are dates.
