How to open your first PDF file

Before you can use most APIs from Radaee Core Lib, you have to activate it with your license. To do so, call the following method before everything starts.

using com.radaee.reader;

......

RDPDFLib.pdf.PDFGlobal.ActiveLicense(2, "[Company_name]", "[Mail]", "[License]");

In any .xaml file which you want to display the PDF file content.

Prepare a RelativePanel as a PDF document content container.

<RelativePanel Name="[Your_Container_Name]" />

Select a PDF document file from your local drive by using FileOpenPicker

FileOpenPicker filePicker;
filePicker = new FileOpenPicker();
filePicker.ViewMode = PickerViewMode.List;
filePicker.SuggestedStartLocation = PickerLocationId.DocumentsLibrary;
filePicker.FileTypeFilter.Add(".PDF");
filePicker.FileTypeFilter.Add(".pdf");
StorageFile file = await filePicker.PickSingleFileAsync();
if (file != null){
     // Application now has read/write access to the picked file
     IRandomAccessStream stream = await
     file.OpenAsync(FileAccessMode.ReadWrite);
     if (stream != null)
     {
        pdf_open(stream, "");
     }
}

Open PDF document file:

private void pdf_open(IRandomAccessStream stream, String password){
    PDFDoc doc = new PDFDoc();
    PDF_ERROR err = doc.Open(stream, password);
    switch (err) {
      case PDF_ERROR.err_open:
        break;
      case PDF_ERROR.err_invalid_para:
        break;
      case PDF_ERROR.err_encrypt:
        break;
      case PDF_ERROR.err_bad_file:
        break;
      case PDF_ERROR.err_password:
        break;
      case PDF_ERROR.err_ok:
        show_PDF(stream, doc);
        break;
      default:
        break;
    }
}

Show PDF document content in container:

private void show_PDF(IRandomAccessStream stream, PDFDoc doc){
    PDFReader reader = new PDFReader();
    reader.PDFOpen(“[Your_Container_Name]”, doc, 
    PDF_LAYOUT_MODE.layout_vert, null);
}
