Open a Document ​

ComPDFKit supports opening local PDF documents or creating new ones.

Open a Local PDF Document ​

The steps to open a local PDF document using a file path are as follows:

1. Obtain the local file path.
2. Initialize a CDFDocument object using the file path.

This example shows how to open a local PDF document:

// Initialize a `CPDFDocument` object using the PDF file path.
CPDFDocument document = CPDFDocument.InitWithFilePath(myFilePath);

if(document.ErrorType != CPDFDocumentError.CPDFDocumentErrorSuccess
  && document.ErrorType != CPDFDocumentError.CPDFDocumentPasswordError)
{
    return;
}

// For encrypted documents, it is necessary to use a password to decrypt them.
if(document.IsLocked)
{
    document.UnlockWithPassword(password);
}

Create a New PDF Document ​

This example shows how to create a new PDF document:

CPDFDocument document = CPDFDocument.CreateDocument();

By default, a newly created document doesn't contain any pages. Please refer to the "Document Editing" functionality to learn how to create new pages and add existing pages to the document.
