-# rotating-a-PDF-document-using-csharp
-This repository contains examples for rotating a PDF page, text, table and image in PDF document using C#
+# Rotating a PDF using .Net Console
+
+The [Syncfusion PDF Library](https://www.syncfusion.com/document-processing/pdf-framework/net/pdf-library) provides support to rotating a PDF document. The library also provides APIs for changing the orientation of a PDF document by a specified degree.
+
+This article will cover the process to rotate a page, text, image and table from a PDF document using the Syncfusion .NET PDF library. The topics related to this will be discussed in the following sections of this post:
+
+Name | Description
+--- | ---
+[Rotating a page in PDF](https://github.com/SyncfusionExamples/rotating-a-PDF-document-using-csharp/master/RotatePDFPage) | It means changing the orientation of the page by a specified degree.
+[Rotating a text in PDF](https://github.com/SyncfusionExamples/rotating-a-PDF-document-using-csharp/master/RotatePDFText) | It means changing the orientation of the text by a specified degree.
+[Rotating an image in PDF](https://github.com/SyncfusionExamples/rotating-a-PDF-document-using-csharp/master/RotatePDFImage) | It means changing the orientation of the image by a specified degree.
+[Rotating a Table in PDF](https://github.com/SyncfusionExamples/rotating-a-PDF-document-using-csharp/master/RotatePDFTable) | It means changing the orientation of the table by a specified degree.
+
+
+
+## Rotating a page in PDF using C#
+
+Rotating a PDF page means changing the orientation of the page by a specified degree.
+
+The following code example shows how to rotate a page to a PDF file using C#.
+
+```csharp
+//Load PDF document as stream.  
+FileStream inputStream = new FileStream("Input.pdf", FileMode.Open, FileAccess.Read, FileShare.ReadWrite); 
+//Load the existing PDF document.  
+PdfLoadedDocument loadedDocument = new PdfLoadedDocument(inputStream); 
+for (int i = 0; i < loadedDocument.PageCount; i++) 
+{ 
+    //Gets the page. 
+    PdfPageBase loadedPage = loadedDocument.Pages[i] as PdfPageBase; 
+    //Set the rotation for loaded page.  
+    loadedPage.Rotation = PdfPageRotateAngle.RotateAngle90; 
+} 
+//Create the filestream to save the PDF document.   
+using(FileStream fileStream = new FileStream("Output.pdf", FileMode.CreateNew, FileAccess.ReadWrite)) 
+{ 
+loadedDocument.Save(fileStream); 
+} 
+//Close the document.  
+loadedDocument.Close(true); 
+```
+By executing this code example, you will get a PDF document like the following screenshot.
+
+<img src="Screenshot/PageOutput.png" alt="Add attachment output" width="100%" Height="Auto"/>
+
+
+## Rotating a text in PDF using C#
+
+Rotating a PDF text means changing the orientation of the text by a specified degree.
+
+The following code example shows how to rotate a text to a PDF file using C#.
+
+```csharp
+//Create a new PDF document. 
+PdfDocument pdfDocument = new PdfDocument(); 
+//Add a page to the PDF document. 
+PdfPage pdfPage = pdfDocument.Pages.Add(); 
+//Create PDF graphics for the page. 
+PdfGraphics graphics = pdfPage.Graphics; 
+//Set the font. 
+PdfFont font = new PdfStandardFont(PdfFontFamily.Helvetica, 20); 
+//Add watermark text. 
+PdfGraphicsState state = graphics.Save(); 
+graphics.RotateTransform(-40); 
+graphics.DrawString("Rotating a text in PDF document", font, PdfPens.Red, PdfBrushes.Red, new PointF(-150, 450)); 
+
+//Create the filestream to save the PDF document.  
+FileStream fileStream = new FileStream("Output.pdf", FileMode.CreateNew, FileAccess.ReadWrite); 
+pdfDocument.Save(fileStream); 
+//Close the document. 
+pdfDocument.Close(true);
+```
+By executing this code example, you will get a PDF document like the following screenshot.
+
+<img src="Screenshot/TextOutput.png" alt="Add attachment output" width="100%" Height="Auto"/>
+
+## Rotating an image in PDF using C#
+
+Rotating a PDF image means changing the orientation of the image by a specified degree.
+
+The following code example shows how to rotate an image to a PDF file using C#.
+
+```csharp
+//Created the PDF document. 
+PdfDocument document = new PdfDocument(); 
+//Add a new page 
+PdfPage page = document.Pages.Add(); 
+FileStream imageStream = new FileStream("Input.png", FileMode.Open, FileAccess.Read, FileShare.ReadWrite); 
+//Load a bitmap 
+PdfBitmap image = new PdfBitmap(imageStream); 
+//save the current graphics state 
+PdfGraphicsState state = page.Graphics.Save(); 
+//Rotate the coordinate system 
+page.Graphics.RotateTransform(-40); 
+//Draw image 
+image.Draw(page, -150, 450); 
+//Restore the graphics state 
+page.Graphics.Restore(state); 
+
+//Create the filestream to save the PDF document.  
+FileStream fileStream = new FileStream("Output.pdf", FileMode.CreateNew, FileAccess.ReadWrite); 
+document.Save(fileStream); 
+//Close the document. 
+document.Close(true); 
+```
+By executing this code example, you will get a PDF document like the following screenshot.
+
+<img src="Screenshot/ImageOutput.png" alt="Add attachment output" width="100%" Height="Auto"/>
+
+## Rotating a table in PDF using C#
+
+Rotating a PDF table means changing the orientation of the table by a specified degree.
+
+The following code example shows how to rotate an table to a PDF file using C#.
+
+```csharp
+//Create a new PDF document. 
+PdfDocument document = new PdfDocument(); 
+//Add a page. 
+PdfPage page = document.Pages.Add(); 
+//Create a PdfGrid. 
+PdfGrid pdfGrid = new PdfGrid(); 
+//Add a handler to rotate the table. 
+pdfGrid.BeginPageLayout += PdfGrid_BeginPageLayout; 
+//Create a DataTable. 
+DataTable dataTable = new DataTable(); 
+
+//Add columns to the DataTable. 
+dataTable.Columns.Add("ID", typeof(int)); 
+dataTable.Columns.Add("Name", typeof(string)); 
+dataTable.Columns.Add("Type", typeof(string)); 
+dataTable.Columns.Add("Date", typeof(DateTime)); 
+//Add rows to the DataTable. 
+for (int i = 0; i < 10; i++) 
+{ 
+    dataTable.Rows.Add(57, "AAA", "ABC", DateTime.Now); 
+    dataTable.Rows.Add(130, "BBB", "BCD", DateTime.Now); 
+    dataTable.Rows.Add(92, "CCC", "CDE", DateTime.Now); 
+} 
+//Assign data source. 
+pdfGrid.DataSource = dataTable; 
+//Set a repeat header for the table.  
+pdfGrid.RepeatHeader = true; 
+//Draw a grid to the page of a PDF document. 
+pdfGrid.Draw(page, new RectangleF(100, 20, 0, page.GetClientSize().Width)); 
+
+//Create the filestream to save the PDF document.  
+FileStream fileStream = new FileStream("Output.pdf", FileMode.CreateNew, FileAccess.ReadWrite); 
+document.Save(fileStream); 
+//Close the document. 
+document.Close(true); 
+
+
+void PdfGrid_BeginPageLayout(object sender, Syncfusion.Pdf.Graphics.BeginPageLayoutEventArgs e) 
+{ 
+    PdfPage page = e.Page; 
+    PdfGraphics graphics = e.Page.Graphics; 
+    //Translate the coordinate system to the required position. 
+    graphics.TranslateTransform(page.GetClientSize().Width, 0); 
+    //Rotate the coordinate system. 
+    graphics.RotateTransform(90); 
+} 
+```
+By executing this code example, you will get a PDF document like the following screenshot.
+
+<img src="Screenshot/TableOutput.png" alt="Add attachment output" width="100%" Height="Auto"/>
