        public static Document create​(Stream stream,
                              Conformance conformance,
                              Encryption encryption)
                       throws java.io.IOException,
                              ConformanceException

        Create a new PDF document.

        Documents with created with this method are writable and can be modified.
        Parameters:
        stream -

        The stream where the PDF document is stored.

        Both, read and write access is required.

        conformance -

        The required conformance level of the PDF document. Adding pages or content from incompatible documents or using incompatible features will lead to a conformance error.

        When using null, the conformance is determined automatically, based on the conformance of the input documents and the requirements of the used features.

        Note that for PDF/A document it is highly recommended to set an output intent using setOutputIntent(com.pdf_tools.fourheights.pdftoolbox.pdf.content.IccBasedColorSpace).

        encryption - the optional encryption parameters
        Returns:
        the newly created document instance
        Throws:
        java.io.IOException - Error writing to the stream.

        java.lang.IllegalArgumentException - if stream is null

                                     ConformanceException

        Create a new PDF document and an associated FDF.

        Documents with created with this method are writable and can be modified. When creating a document with this method, all annotations.MarkupAnnotations - created or copied - are stored as an FDF file to the fdfStream. In the output PDF (pdfStream), only annotations that are not annotations.MarkupAnnotations are stored.
        Parameters:
        pdfStream -

        The stream where the PDF document is stored.

        Both, read and write access is required. The resulting PDF document contains no annotations.MarkupAnnotations.

        fdfStream -

        The stream where the document's annotations.MarkupAnnotations are stored in the FDF format.

        Both, read and write access is required.

        conformance -

        The required conformance level of the PDF document. Adding pages or content from incompatible documents or using incompatible features will lead to a conformance error.

        When using null, the conformance is determined automatically, based on the conformance of the input documents and the requirements of the used features.

        Note that for PDF/A document it is highly recommended to set an output intent using setOutputIntent(com.pdf_tools.fourheights.pdftoolbox.pdf.content.IccBasedColorSpace).

        java.lang.IllegalArgumentException - if pdfStream is null
        java.lang.IllegalArgumentException - if fdfStream is null
