NewPDF(PdfConformance) Method

In This Topic

Prepares a brand new empty PDF document within a GdPicturePDF object. The PDF conformance level of this PDF document will be set according to the parameter specified by you.

PDF/A is an ISO-standardized version of the PDF specialized for the digital preservation of electronic documents. It is a subset of the PDF standard which excludes those PDF features that give rise to concerns about security and the ability to archive documents long term.

You will always need an object of the GdPicturePDF class to create a new common PDF or PDF/A document. Please note that a newly created GdPicturePDF object does not automatically create a new document. The created document also does not contain any pages. You are also able to reuse the created GdPicturePDF object for manipulation with another PDF document simply by calling this method again.

Public Overloads Function NewPDF( _

) As GdPictureStatus

public GdPictureStatus NewPDF( 
   PdfConformance Conformance
)

public function NewPDF( 
    Conformance: PdfConformance
): GdPictureStatus;

public function NewPDF( 
   Conformance : PdfConformance
) : GdPictureStatus;

public: GdPictureStatus NewPDF( 
   PdfConformance Conformance
)

public:
GdPictureStatus NewPDF( 
   PdfConformance Conformance
)

Parameters

Conformance: A member of the PdfConformance enumeration. Specifies the required conformance to the PDF or PDF/A standard of a newly created PDF document.
Setting this parameter to PdfConformance.PDF does the same as what the NewPDF method does.

Return Value

A member of the GdPictureStatus enumeration. If the method has been successfully followed, then the return value is GdPictureStatus.OK.

We strongly recommend always checking this status first.

Remarks

If you use the value of the PdfConformance.PDF, the toolkit will create the PDF document conformed to the lowest PDF version (version 1.3 is the minimum) based on what the output PDF document will contain.

The origin's location and the measurement unit for any newly created document are reset to their default values: PdfOrigin.PdfOriginBottomLeft, PdfMeasurementUnit.PdfMeasurementUnitPoint.

This method requires the PDF Processing component to run.

Example

How to create a new single page PDF/A-1a compliant document with the "Hello World" written in the middle of the first page.
