Hello support team,

We faced an exception that ShadingType 1 is not supported. Can you please confirm that this is expected?

Handle the import of incrementally updated documents with invalid cross-reference offsets.

Some PDF files have an additional content added before the file header (before %PDF-1.4 for example). This additional content makes all byte offsets in the document invalid, which causes the format provider to throw an exception.

At this point, to import a similar document it should be pre-processed so the content before the version header is removed before importing it.

When importing a large document (e.g. 2.3GB) , the library fails to parse int value that exceeds the limit which leads to endless importing:

Handle the import of documents with a negative cross-reference stream offset.

You need to explicitly set the correct MIME type when embedding the file into the PDF. This is especially important for standards like PDF/A-3 and Factur-X, which require strict metadata and MIME type declarations for embedded files.

The default value /application/octet-stream is too generic and not compliant for XML attachments.

 

Documents can be signed using the end certificate of a certificate chain, instead of the whole chain. This improves the performance of the signing.

In version 1 there are three profiles that have different levels of detail in their structure: Basic (B), Comfort (C) and Extended (X): https://mind-forms.de/e-rechnung/welches-zugferd-profil-kann-ich-verwenden/ 

Add support for encrypting documents with an AES-128 algorithm.

Add support for the PAdES-BES signature standard

Add support for /TR (Transfer Function) property of SMask.

When importing a document with an invalid creation or modification date, an exception is thrown:

• FormatException: 'The input string '' was not in a correct format.'
• ArgumentOutOfRangeException: 'Year, Month, and Day parameters describe an unrepresentable DateTime.'

From the Part 4: PAdES Long Term - PAdES-LTV Profile (ETSI TS 102 778-4) Specification: 

"Validation of an electronic signature requires data to validate the signature such as CA certificates, Certificate Revocation List (CRLs) or Certificate status information (OCSP) commonly provided by an online service (referred to in the present document as validation data). If the document is stored and the signatures are to be verifiable long after first created, in particular after the signing certificate has expired, the original validation data may no longer available or there may uncertainty as to what validation data was used when the document was first verified."

When writing a RadFixedPage containing widgets using the PdfPageStreamWriter.WriteContent() method an exception is thrown.

The exception: System.ArgumentNullException: 'Value cannot be null. Parameter name: context'

Provide an API for externally signing the document hash.

Add support for ShadingType 1.

Currently, you cannot sort filtered cell ranges that contain merged cells. This is supported in Excel.

Handle the import of documents with an invalid cross-reference stream offset.

XlsFormatProvider: Add support for hidden rows.

Add support for Fields when exporting to TXT format. When a field is exported to *.txt, only the result should be exported (as in HTML). In the current implementation, the field characters, field code, and field result are all exported.
