This repository contains examples for rotating a PDF page, text, table and image in PDF document using C#
1+
# Rotating a PDF using .Net Console
2+
3+
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.
4+
5+
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:

## Rotating a page in PDF using C#
17+
18+
Rotating a PDF page means changing the orientation of the page by a specified degree.
19+
20+
The following code example shows how to rotate a page to a PDF file using C#.
21+
22+
```csharp
23+
//Load PDF document as stream.
24+
FileStream inputStream = new FileStream("Input.pdf", FileMode.Open, FileAccess.Read, FileShare.ReadWrite);
25+
//Load the existing PDF document.
26+
PdfLoadedDocument loadedDocument = new PdfLoadedDocument(inputStream);
27+
for (int i = 0; i < loadedDocument.PageCount; i++)
28+
{
29+
//Gets the page.
30+
PdfPageBase loadedPage = loadedDocument.Pages[i] as PdfPageBase;
31+
//Set the rotation for loaded page.
32+
loadedPage.Rotation = PdfPageRotateAngle.RotateAngle90;
33+
}
34+
//Create the filestream to save the PDF document.
35+
using(FileStream fileStream = new FileStream("Output.pdf", FileMode.CreateNew, FileAccess.ReadWrite))
36+
{
37+
loadedDocument.Save(fileStream);
38+
}
39+
//Close the document.
40+
loadedDocument.Close(true);
41+
```
42+
By executing this code example, you will get a PDF document like the following screenshot.
43+
44+
<img src="Screenshot/PageOutput.png" alt="Add attachment output" width="100%" Height="Auto"/>
45+
46+
47+
## Rotating a text in PDF using C#
48+
49+
Rotating a PDF text means changing the orientation of the text by a specified degree.
50+
51+
The following code example shows how to rotate a text to a PDF file using C#.
52+
53+
```csharp
54+
//Create a new PDF document.
55+
PdfDocument pdfDocument = new PdfDocument();
56+
//Add a page to the PDF document.
57+
PdfPage pdfPage = pdfDocument.Pages.Add();
58+
//Create PDF graphics for the page.
59+
PdfGraphics graphics = pdfPage.Graphics;
60+
//Set the font.
61+
PdfFont font = new PdfStandardFont(PdfFontFamily.Helvetica, 20);
62+
//Add watermark text.
63+
PdfGraphicsState state = graphics.Save();
64+
graphics.RotateTransform(-40);
65+
graphics.DrawString("Rotating a text in PDF document", font, PdfPens.Red, PdfBrushes.Red, new PointF(-150, 450));
66+
67+
//Create the filestream to save the PDF document.
68+
FileStream fileStream = new FileStream("Output.pdf", FileMode.CreateNew, FileAccess.ReadWrite);
69+
pdfDocument.Save(fileStream);
70+
//Close the document.
71+
pdfDocument.Close(true);
72+
```
73+
By executing this code example, you will get a PDF document like the following screenshot.
74+
75+
<img src="Screenshot/TextOutput.png" alt="Add attachment output" width="100%" Height="Auto"/>
76+
77+
## Rotating an image in PDF using C#
78+
79+
Rotating a PDF image means changing the orientation of the image by a specified degree.
80+
81+
The following code example shows how to rotate an image to a PDF file using C#.
82+
83+
```csharp
84+
//Created the PDF document.
85+
PdfDocument document = new PdfDocument();
86+
//Add a new page
87+
PdfPage page = document.Pages.Add();
88+
FileStream imageStream = new FileStream("Input.png", FileMode.Open, FileAccess.Read, FileShare.ReadWrite);
89+
//Load a bitmap
90+
PdfBitmap image = new PdfBitmap(imageStream);
91+
//save the current graphics state
92+
PdfGraphicsState state = page.Graphics.Save();
93+
//Rotate the coordinate system
94+
page.Graphics.RotateTransform(-40);
95+
//Draw image
96+
image.Draw(page, -150, 450);
97+
//Restore the graphics state
98+
page.Graphics.Restore(state);
99+
100+
//Create the filestream to save the PDF document.
101+
FileStream fileStream = new FileStream("Output.pdf", FileMode.CreateNew, FileAccess.ReadWrite);
102+
document.Save(fileStream);
103+
//Close the document.
104+
document.Close(true);
105+
```
106+
By executing this code example, you will get a PDF document like the following screenshot.
107+
108+
<img src="Screenshot/ImageOutput.png" alt="Add attachment output" width="100%" Height="Auto"/>
109+
110+
## Rotating a table in PDF using C#
111+
112+
Rotating a PDF table means changing the orientation of the table by a specified degree.
113+
114+
The following code example shows how to rotate an table to a PDF file using C#.
115+
116+
```csharp
117+
//Create a new PDF document.
118+
PdfDocument document = new PdfDocument();
119+
//Add a page.
120+
PdfPage page = document.Pages.Add();
121+
//Create a PdfGrid.
122+
PdfGrid pdfGrid = new PdfGrid();
123+
//Add a handler to rotate the table.
124+
pdfGrid.BeginPageLayout += PdfGrid_BeginPageLayout;
125+
//Create a DataTable.
126+
DataTable dataTable = new DataTable();
127+
128+
//Add columns to the DataTable.
129+
dataTable.Columns.Add("ID", typeof(int));
130+
dataTable.Columns.Add("Name", typeof(string));
131+
dataTable.Columns.Add("Type", typeof(string));
132+
dataTable.Columns.Add("Date", typeof(DateTime));
133+
//Add rows to the DataTable.
134+
for (int i = 0; i < 10; i++)
135+
{
136+
dataTable.Rows.Add(57, "AAA", "ABC", DateTime.Now);
137+
dataTable.Rows.Add(130, "BBB", "BCD", DateTime.Now);
138+
dataTable.Rows.Add(92, "CCC", "CDE", DateTime.Now);
139+
}
140+
//Assign data source.
141+
pdfGrid.DataSource = dataTable;
142+
//Set a repeat header for the table.
143+
pdfGrid.RepeatHeader = true;
144+
//Draw a grid to the page of a PDF document.
145+
pdfGrid.Draw(page, new RectangleF(100, 20, 0, page.GetClientSize().Width));
146+
147+
//Create the filestream to save the PDF document.
148+
FileStream fileStream = new FileStream("Output.pdf", FileMode.CreateNew, FileAccess.ReadWrite);
149+
document.Save(fileStream);
150+
//Close the document.
151+
document.Close(true);
152+
153+
154+
void PdfGrid_BeginPageLayout(object sender, Syncfusion.Pdf.Graphics.BeginPageLayoutEventArgs e)
155+
{
156+
PdfPage page = e.Page;
157+
PdfGraphics graphics = e.Page.Graphics;
158+
//Translate the coordinate system to the required position.
159+
graphics.TranslateTransform(page.GetClientSize().Width, 0);
160+
//Rotate the coordinate system.
161+
graphics.RotateTransform(90);
162+
}
163+
```
164+
By executing this code example, you will get a PDF document like the following screenshot.
165+
166+
<img src="Screenshot/TableOutput.png" alt="Add attachment output" width="100%" Height="Auto"/>
167+
