----
-
-# Concept and Features
-
-Essential PDF Viewer can display PDF files, and print and export the pages as raster images. This section explains about the various functionalities available in the Essential PDF viewer for WPF.
-
-## Viewing PDF Files 
-
-A PDF can be loaded into the PDF Viewer either through the File Open dialog available in the toolbar or through the Load method. It also requests passwords to open encrypted documents.
-
-{% highlight c# %}
-
-//Initialize PDF Viewer.
-
-PdfViewerControl pdfViewer1 = new PdfViewerControl();
-
-
-
-//Load the PDF.
-
-pdfViewer1.Load("Template.pdf");
-{% endhighlight %}
-
-
-{% highlight vbnet %}
-
-'Initialize PDF Viewer.
-
-Private pdfViewer1 As New PdfViewerControl()
-
-
-
-'Load the PDF.
-
-pdfViewer1.Load("Template.pdf")
-
-{% endhighlight %}
-
-You can load an encrypted document by using the overload in the Load method.
-
-{% highlight c# %}
-
-//Initialize PDF Viewer.
-
-PdfViewerControl pdfViewer1 = new PdfViewerControl();
-
-
-
-//Load the PDF.
-
-pdfViewer1.Load("Template.pdf", "password");
-
-{% endhighlight %}
-
-{% highlight vbnet %}
-
-'Initialize PDF Viewer.
-
-Private pdfViewer1 As New PdfViewerControl()
-
-
-
-'Load the PDF.
-
-pdfViewer1.Load("Template.pdf", "password")
-
-{% endhighlight %}
-
-You can also load the PDF document by setting its path to the ItemSource property
-
-{% highlight c# %}
-
-//Initialize PDF Viewer.
-
-PdfViewerControl pdfViewer1 = new PdfViewerControl();
-
-
-
-//Load the PDF.
-
-pdfViewer1. ItemSource="Template.pdf";
-{% endhighlight %}
-
-
-{% highlight vbnet %}
-
-'Initialize PDF Viewer.
-
-Private pdfViewer1 As New PdfViewerControl()
-
-
-
-'Load the PDF.
-
-pdfViewer1. ItemSource = "Template.pdf"
-{% endhighlight %}
-
-### Saving the PDF document
-
-PDF Viewer also allows you to save the PDF document that is being displayed in the PDF Viewer. The following code example illustrates the same.
-
-{% highlight c# %}
-
-
-
-//Acquire the document loaded into the PDF Viewer
-
-PdfLoadedDocument lDoc = pdfviewer1.LoadedDocument;
-
-
-
-//Save the document
-
-lDoc.Save("Sample.pdf");
-
-{% endhighlight %}
-
-{% highlight vbnet %}
-
-'Acquire the document loaded into the PDF Viewer
-
-Dim lDoc As PdfLoadedDocument = pdfviewer1.LoadedDocument
-
-
-
-'Save the document
-
-lDoc.Save("Sample.pdf")
-{% endhighlight %}
-
-### Navigating through the pages
-
-PDF Viewer allows you to navigate through the pages of the PDF document. The following code example illustrates the navigation to page 2 of the PDF document.
-
-{% highlight c# %}
-

-
-{% highlight c# %}
-
-// Hiding the default toolbar of the PDF Viewer
-
-pdfviewer1.ShowToolbar = false;
-{% endhighlight %}
-
-
-
-
-{% highlight vbnet %}
-
-' Hiding the default toolbar of the PDF Viewer
-
-pdfviewer1.ShowToolbar = False
-{% endhighlight %}
-
-### Toggling visibility of the scroll bar
-
-PDF Viewer supports showing and hiding scrollbar, when you feel to use the PDF Viewer only with the touch support, you can hide the default scrollbars of the PDF Viewer. The following code example hides the scrollbar in the PDF Viewer control.
-
-{% highlight c# %}
-
-// Hiding the scrollbar of the PDF Viewer
-
-pdfviewer1.ShowScrollbar = false;
-
-
-{% endhighlight %}
-
-
-{% highlight vbnet %}
-
-' Hiding the scrollbar of the PDF Viewer
-
-pdfviewer1.ShowScrollbar = False
-{% endhighlight %}
-
-### Acquiring current page being displayed
-
-PDF Viewer supports acquiring the index of the page being displayed in the PDF Viewer at any moment. The following code example illustrates the same.
-
-{% highlight c# %}
-
-// Acquiring the number of page being displayed in the Viewer  
-
-int pageCount = pdfviewer1.CurrentPageIndex;
-
-
-{% endhighlight %}
-
-
-{% highlight vbnet %}
-
-' Acquiring the number of page being displayed in the Viewer  
-
-Dim pageCount As Integer = pdfviewer1. CurrentPageIndex
-{% endhighlight %}
-
-### Enabling and Disabling Notification bar
-
-Notification bar is a part of the PDF Viewer that is used to display when an unexpected error occurs in the PDF Viewer control. You can suppress the display of the Notification bar by setting the EnableNotificationBar property to false. The following code example illustrate the same.

-
-' Hiding the scrollbar of the PDF Viewer
-
-pdfviewer1.EnableNotificationBar= False
-{% endhighlight %}
-
-### Printing PDF Files 
-
-PDF Viewer allows printing loaded PDFs using the Print button in the toolbar. The following Print dialog opens upon triggering the Print button.
-
-![Concept-and-Features_images1](Concept-and-Features_images/Concept-and-Features_img1.png)
-
-
-
-#### Silent Printing
-
-The PrintDocument property of PdfViewerControl returns System.Drawing.Printing.PrintDocument that helps to complete printing using PrintDialog. This type of printing can be used when trying to print the PDF document with the custom printer settings. The following code sample demonstrates this:
-
-{% highlight c# %}
-
-PrintDialog dialog = new PrintDialog();
-
-dialog.AllowPrintToFile = true;         
-
-dialog.Document = viewer.PrintDocument;
-
-dialog.Document.Print();
-{% endhighlight %}
-
-
-{% highlight vbnet %}
-
-Dim dialog As New PrintDialog()
-
-dialog.AllowPrintToFile = True
-
-dialog.Document = viewer.PrintDocument
-
-dialog.Document.Print()
-{% endhighlight %}
-
-
-When you prefer to perform Silent printing with the default printer settings, then using Print method in the PDF Viewer control is the best approach. The following code example illustrates the same.
-
-{% highlight c# %}
-
-// Printing document using Print method
-
-pdfviewer1.Print();
-
-{% endhighlight %}
-
-
-
-{% highlight vbnet %}
-
-' Printing document using Print method
-
-pdfviewer1.Print()
-{% endhighlight %}
-
-### Exporting PDF
-
-#### Exporting PDFs as Raster Images
-
-Essential PDF Viewer allows selected pages to be exported as raster images. Exporting can be done using the ExportAsImage method. This option helps to convert a PDF into an image.
-
-{% highlight c# %}
-
-Bitmap img = pdfViewer1.ExportAsImage(0);
-
-
-
-// Save the image.
-
-img.Save("Sample.png", ImageFormat.Png);
-
-{% endhighlight %}
-
-{% highlight vbnet %}
-
-Dim img As Bitmap = pdfViewer1.ExportAsImage(0)
-
-
-
-' Save the image.
-
-img.Save("Sample.png", ImageFormat.Png)
-{% endhighlight %}
-
-
-You can also specify the page range instead of converting each page.
-
-{% highlight c# %}
-
-Bitmap[] img = pdfViewer1.ExportAsImage(0, 3);
-
-{% endhighlight %}
-
-{% highlight vbnet %}
-
-Dim img() As Bitmap = pdfViewer1.ExportAsImage(0, 3)
-{% endhighlight %}
-
-#### Exporting PDFs as Vector Images
-
-Exporting PDFs as vector images can be done using the ExportAsMetafile method. The following code sample demonstrates how a PDF document can be exported as a Metafile.
-
-{% highlight c# %}
-
-Metafile img = pdfViewer1.ExportAsMetafile(0);
-
-
-
-// Save the image
-
-img.Save("Sample.emf", ImageFormat.Emf);
-{% endhighlight %}
-
-
-{% highlight vbnet %}
-
-Dim img As Metafile = pdfViewer1.ExportAsMetafile(0)
-
-
-
-' Save the image
-
-img.Save("Sample.emf", ImageFormat.Emf)
-{% endhighlight %}
-
-
-You can also specify the page range instead of converting each page individually.
-
-{% highlight c# %}
-
-Metafile[] img = pdfViewer1.ExportAsMetafile(0, 3);
-
-{% endhighlight %}
-
-{% highlight vbnet %}
-
-Dim img() As Metafile = pdfViewer1.ExportAsMetafile(0, 3)
-{% endhighlight %}
-
-### Searching Text
-
-Essential PDF Viewer allows you to search and highlight the text in the PDF document. The search box appears when Ctrl+F is pressed and searches the text in the PDF document as displayed in the following screenshot.
-
-![Concept-and-Features_images2](Concept-and-Features_images/Concept-and-Features_img2.png)
-
-
-
-The PDF Viewer control also supports searching text in the PDF document with the help of the following API. The FindText method returns true when the text given is found in the document. The dictionary contains the page index and the list of rectangular coordinates of the text found in that page. The following code example illustrates how text search can be achieved in the PDF Viewer control.
-
-{% highlight c# %}
-
-bool IsMatchFound;
-
-pdfViewerControl1.Load("../../Data/Barcode.pdf");
-
-
-
-//Get the occurrences of the target text and location.
-
-Dictionary<int, List<RectangleF>> 
-
-          textSearch = new Dictionary<int, List<RectangleF>>();
-
-IsMatchFound = pdfViewerControl1.FindText("targetText", out textSearch);
-
-{% endhighlight %}
-
-{% highlight vbnet %}
-
-Dim IsMatchFound As Boolean
-
-pdfViewerControl1.Load("../../Data/Barcode.pdf")
-
-
-
-'Get the occurrences of the target text and location.
-
-Dim textSearch As New Dictionary(Of Integer, List(Of RectangleF))()
-
-IsMatchFound = pdfViewerControl1.FindText("targetText", textSearch)
-{% endhighlight %}
-
