Introduction to SQL CLR and Spire.PDF
SQL CLR is technology for hosting of the Microsoft .NET common language runtime engine within SQL Server. The SQLCLR allows managed code to be hosted by, and run in, the Microsoft SQL Server environment.
This technology, introduced in Microsoft SQL Server 2005, allow users for example to create the following types of managed code objects in SQL Server in .NET languages such as C# or VB.NET.
- Stored Procedures
- User defined aggregates
- Triggers
- User defined types
- User defined functions
Spire.PDF is a PDF library which contains an incredible wealth of features to create, read, edit and manipulate PDF documents on .NET, Silverlight and WPF Platform. As an independent PDF library, it does not need users to install Adobe Acrobat or any other third party libraries. Spire.PDF for .NET is completely written in C#, but also supports VB.NET, Windows Forms and ASP.NET Applications.
How to Utilize Spire.PDF in SQL CLR?
In this article we will see, how to create a simple PDF document in SQL CLR using Spire.PDF and how to deploy it in SQL Server. Just follow following steps and it will get done.
Enabling SQL CLR Integration
For SQL Server is, SQL CLR assembly is an external code, so in SQL Server default installation configuration, SQL CLR is blocked not used, to use it, we must first open it.
- Open SQL Server Management Studio, connect and create a new database named SpirePDFCLR.
- Enable the SQL CLR with the following code.
sp_configure 'clr enabled', 1 GO RECONFIGURE GO
Now the SQL Server is ready to execute the database objects that are built using the C# programming language.
Adding Dependency Assemblies
For the sake of using non-SAFE CLR Assemblies, firstly we need to turn Trustworthy on.
ALTER DATABASE SpirePDFCLR SET TRUSTWORTHY ON
Now, we can add the dependency assemblies by following code.
CREATE ASSEMBLY [System.Windows.Forms] FROM'C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Windows.Forms.dll' WITH PERMISSION_SET=UNSAFE CREATE ASSEMBLY [System.Web] FROM 'C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.Web.dll' WITH PERMISSION_SET=UNSAFE CREATE ASSEMBLY [Microsoft.mshtml] FROM'C:\Windows\Microsoft.NET\Framework\v2.0.50727\Microsoft.mshtml.dll' WITH PERMISSION_SET=UNSAFE
Once these assemblies are added, we can add the Spire.Pdf.Dll.
CREATE ASSEMBLY [Spire.Pdf] FROM 'D:\NET2.0\Spire.Pdf.dll' WITH PERMISSION_SET=UNSAFE
Then go to the Object Browser, select the SpirePDFCLR database, right-click and choose "Refresh". They will be shown under Assemblies as below.
Creating and Manipulate PDF document in SQL CLR
Once the Spire.Pdf.dll is added into the database, we can create and manipulate the PDF document in SQL CLR. Here we will take a Stored Procedure as an example.
Put the following code in the Stored Procedure. It will create a PDF document when we execute the Stored Procedure.
using System;
using System.Data;
using System.Data.SqlClient;
using System.Data.SqlTypes;
using Microsoft.SqlServer.Server;
using Spire.Pdf;
using Spire.Pdf.Graphics;
public partial class UserDefinedFunctions
{
[Microsoft.SqlServer.Server.SqlProcedure]
public static void StoreProcedure()
{
PdfDocument doc = new PdfDocument();
PdfPageBase page = doc.Pages.Add();
page.Canvas.DrawString("Hello world", new PdfFont(PdfFontFamily.Courier, 100), PdfBrushes.Black, 0, 0);
doc.SaveToFile("d:\\result.pdf");
}
};
Next build and deploy the solution. If everything is fine then it will say that the deployment was successful. Then we will see the Store Procedure in the SpirePDFCLR database.
Now we will run the Stored Procedure from SQL Server, but here we will get an error as below.
We need to change the permission level of the CLR project as unsafe and deploy it again.
Now run it again, it will work fine and we will get the PDF document.
One of our customers has a requirement to insert text to a Word document in an exact location (horizontal and vertical coordinates). Generally, people position text in a Word document by using other tools such as tables and text boxes, since the positioning of tables and text boxes is much easier to control. In this article, we'll introduce how to position text in Word through text box in C#, VB.NET.
Firstly download Spire.Doc for .NET and reference the dll file to your project. Before we start to code, we also need following namespaces to be extra added.
using System.Drawing; using Spire.Doc; using Spire.Doc.Documents; using Spire.Doc.Fields; using Spire.Doc.Formatting;
Code Snippet:
Step 1: Create a new Word document, add a section for it, and then add a paragraph on the section.
Document doc = new Document(); Section sec = doc.AddSection(); Paragraph par = sec.AddParagraph();
Step 2: Append a new text box to the paragraph. Here we logically set VerticalOrigin and HorizontalOrigin as Margin because horizontal and vertical coordinate is a relative value to his reference object. By giving the variable VerticalPosition and HorizontalPosition a certain value, the text box will be fixed at the position.
TextBox textBox = par.AppendTextBox(180, 30); textBox.Format.VerticalOrigin = VerticalOrigin.Margin; textBox.Format.VerticalPosition = 100; textBox.Format.HorizontalOrigin = HorizontalOrigin.Margin; textBox.Format.HorizontalPosition = 50; textBox.Format.NoLine = true;
Step 3: Define a new format style.
CharacterFormat format = new CharacterFormat(doc); format.FontName = "Calibri"; format.FontSize = 15; format.Bold = true;
Step 4: Add text to text box, and apply the preset format to the text.
Paragraph par1 = textBox.Body.AddParagraph();
par1.AppendText("This is my new string").ApplyCharacterFormat(format);
Step 5: Save the file.
doc.SaveToFile("result.docx", FileFormat.Docx);
Result:
The border line of text box has been set as invisible, therefore we only see the text being added at the specified horizontal and vertical coordinates.

When we add image into word document, of course we want to move it exactly where we want to make our page tidy and beautiful. With the help of Spire.Doc, we can set the wrapping style to adjust the position of the image. Usually there are seven kinds of wrapping styles: In Line with Text, Square, Tight, Through, Top and Bottom, Behind the Text, In Front of Text and Spire.Doc supports all of them. This article will show you how to wrap text around image in C#. Here comes to the steps:
Step 1: Create a new word document and load the document from the file.
Document document = new Document();
document.LoadFromFile("Sample.docx");
Step 2: Add a paragraph for the first section.
Paragraph paragraph = document.Sections[0].AddParagraph();
Step 3: Add a picture in the paragraph.
DocPicture picture = paragraph.AppendPicture(Image.FromFile("image.jpg"));
Step 4: Set text wrapping style to Square.
picture.TextWrappingStyle = TextWrappingStyle.Square;
Step 5: Set text wrapping type to both.
picture.TextWrappingType = TextWrappingType.Both;
Step 6: Save the document to file and process it.
document.SaveToFile(output,FileFormat.Docx); System.Diagnostics.Process.Start(output);

PDF format is the best choice in many cases, but Word is more flexible when editing or modification is needed. PDF files are typically used for online sharing, printing and archiving, while Word documents are used for creating, editing and formatting documents. Converting a PDF to Word is a good option if you want to re-edit the PDF document. In this article, you will learn how to programmatically convert PDF to Word in C# and VB.NET using Spire.PDF for .NET.
Install Spire.PDF for .NET
To begin with, you need to add the DLL files included in the Spire.PDF for.NET package as references in your .NET project. The DLL files can be either downloaded from this link or installed via NuGet.
PM> Install-Package Spire.PDF
Background Knowledge
Spire.PDF for .NET provides two modes of conversion. The advantages and disadvantages of these two modes are as follows:
- Fixed Layout Mode: The fixed layout mode has fast conversion speed and is conducive to maintaining the original appearance of PDF files to the greatest extent. However, the editability of the resulting document will be limited since each line of text in PDF will be presented in a separate frame in the generated Word document.
- Flow Recognition Mode: The flow recognition mode is a full recognition mode. The converted content will not be presented in frames, and the structure of the resulting document is flowable. The generated Word document is easy to re-edit but may look different from the original PDF file.
Convert PDF to Fixed-Layout Doc/Docx in C#, VB.NET
By default, the PdfDcoument.SaveToFile() method will convert PDF to Word with fixed layout. The following are the detailed steps.
- Create a PdfDocument object.
- Load a PDF file using PdfDocument.LoadFromFile() method.
- Convert the PDF document to a Doc or Docx format file using PdfDocument.SaveToFile(String fileName, FileFormat fileFormat) method.
- C#
- VB.NET
using Spire.Pdf;
namespace ConvertPdfToFixedLayoutWord
{
class Program
{
static void Main(string[] args)
{
//Create a PdfDocument object
PdfDocument doc = new PdfDocument();
//Load a PDF document
doc.LoadFromFile("C:\\Users\\Administrator\\Desktop\\sample.pdf");
//Convert PDF to Doc and save it to a specified path
doc.SaveToFile("output/ToDoc.doc", FileFormat.DOC);
//Convert PDF to Docx and save it to a specified path
doc.SaveToFile("output/ToDocx.docx", FileFormat.DOCX);
doc.Close();
}
}
}
Convert PDF to Flexible-Structured Doc/Docx in C#, VB.NET
In addition to the default conversion engine, Spire.PDF for .NET provides another engine called Ps mode, which works better with the flow recognition mode. To enable Ps conversion engine and flow recognition mode, pass (true, true) as the parameters of the PdfDocument.ConvertOptions.SetPdfToDocOptions(bool usePsMode, bool useFlowRecognitionMode) method. The entire steps are as follows.
- Create a PdfDocument object.
- Load a PDF file using PdfDocument.loadFromFile() method.
- Enable Ps conversion engine and flow recognition mode using PdfDocument.ConvertOptions.SetPdfToDocOptions(true, true) method.
- Convert the PDF document to a Doc or Docx format file using PdfDocument.SaveToFile() method.
- C#
- VB.NET
using Spire.Pdf;
namespace ConvertPdfToFlexibleLayoutWord
{
class Program
{
static void Main(string[] args)
{
//Create a PdfDocument object
PdfDocument doc = new PdfDocument();
//Load a PDF document
doc.LoadFromFile("C:\\Users\\Administrator\\Desktop\\sample.pdf");
//Specify the PDF to Word conversion options
doc.ConvertOptions.SetPdfToDocOptions(true, true);
//Convert PDF to Doc
doc.SaveToFile("output/ToDoc.doc", FileFormat.DOC);
//Convert PDF to Docx
doc.SaveToFile("output/ToDocx.docx", FileFormat.DOCX);
doc.Close();
}
}
}

It is pretty easy in MS PowerPoint to export a certain shape as image with following two steps:
- 1. Select the object shape
- 2. From the right-click menu select Save as Picture
However, Spire.Presentation also provides easy method for programmers to save shapes out of slides. In the following section, we’ll introduce how to export shapes as images via Spire.Presentation with an example.
Test File:
As is shown in the screenshot, the sample file for testing contains several shapes on the first slide.
Code Snippet for Exporting Shape as Image:
Step 1: Initialize a new instance of Presentation class and load the test file from disk.
Presentation ppt = new Presentation();
ppt.LoadFromFile("test.pptx");
Step 2: Use for loop to traverse every shape in the slide. Call ShapeList.SaveAsImage(int shapeIndex) to save shape as image, then save this image to the specified file in the specified format.
for (int i = 0; i < ppt.Slides[0].Shapes.Count; i++)
{
Image image = ppt.Slides[0].Shapes.SaveAsImage(i);
image.Save(String.Format("Picture-{0}.png", i), System.Drawing.Imaging.ImageFormat.Png);
}
Output:
Picture-0
Picture-1
Entire Code:
using Spire.Presentation;
using System.Drawing;
namespace ExportShape
{
class Program
{
static void Main(string[] args)
{
//create PPT document
Presentation ppt = new Presentation();
ppt.LoadFromFile("test.pptx");
for (int i = 0; i < ppt.Slides[0].Shapes.Count; i++)
{
Image image = ppt.Slides[0].Shapes.SaveAsImage(i);
image.Save(System.String.Format("Picture-{0}.png", i), System.Drawing.Imaging.ImageFormat.Png);
}
}
}
}

Set the offset of image when the fill way of chart is picture fill
2015-04-17 07:39:10 Written by KoohjiSet offset of the filled image could make your chart background pictures zoom and show proportional as you wish. This article shows how to set the offset of image via Spire.XLS.
Here are the steps:
Step 1: Create an instance of Spire.XLS.Workbook.
Workbook book = new Workbook();
Step 2: Load data and create a contrast sheet.
workbook.LoadFromFile("test.xlsx",ExcelVersion.Version2013);
Worksheet sheet = workbook.Worksheets[0];
Worksheet sheet1 = workbook.Worksheets.Add("Contrast");
Step 3: Add chart1 and background image to sheet1 as comparision.
Chart chart1 = sheet1.Charts.Add(ExcelChartType.ColumnClustered);
chart1.DataRange = sheet.Range["D1:E9"];
chart1.SeriesDataFromRange = false;
chart1.LeftColumn = 1;
chart1.TopRow = 11;
chart1.RightColumn = 8;
chart1.BottomRow = 33;
chart1.ChartArea.Fill.CustomPicture(Image.FromFile("2.jpg"), "None");
Step 4: Add same chart and background image then set offset of image by transforming image in sheet[0] as form of XlsShapeFill. Then set the property of PicStretch of each direction with percentage and Tile property.
Chart chart = sheet.Charts.Add(ExcelChartType.ColumnClustered);
chart.DataRange = sheet.Range["D1:E9"];
chart.SeriesDataFromRange = false;
chart.LeftColumn = 1;
chart.TopRow = 11;
chart.RightColumn = 8;
chart.BottomRow = 33;
chart.ChartArea.Fill.CustomPicture(Image.FromFile("2.jpg"), "None");
IChart ichart = sheet.Charts[0];
(ichart.ChartArea.Fill as XlsShapeFill).Tile = false;
(ichart.ChartArea.Fill as XlsShapeFill).PicStretch.Left = 10;
(ichart.ChartArea.Fill as XlsShapeFill).PicStretch.Top = 20;
(ichart.ChartArea.Fill as XlsShapeFill).PicStretch.Right = 10;
(ichart.ChartArea.Fill as XlsShapeFill).PicStretch.Bottom = 5;

Automatically Display Bookmarks or Thumbnails When PDF is Opened in C#/VB.NET
2015-04-16 02:14:27 Written by KoohjiWhen a user opens a PDF document they see the initial view of the PDF. By default, the Bookmarks Panel or Thumbnails Panel is not shown when the PDF is opened. In this article, we're going to demonstrate how to set document properties so that the Bookmarks Panel or Thumbnails Panel will be open every time the file is launched.
Check the test file below, only the page content is showing when the document is opened.
Code Snippet and Effect:
Step 1: Create a new PDF document and load the test file.
PdfDocument Pdf = new PdfDocument();
Pdf.LoadFromFile("Test.pdf");
Step 2: In the class of ViewerPreferences, there is a PageMode property that specifies how the document should be displayed when opened. Set PageMode as UseOutlines, save the changes to a new PDF file named "ShowBookmarks".
Pdf.ViewerPreferences.PageMode = PdfPageMode.UseOutlines;
Pdf.SaveToFile("ShowBookmarks.pdf");
Open the newly-generated file, Bookmarks Panel will be automatically displayed as below:
Step 3: If we set PageMode as UseThumbs, and save the changes to another PDF file named "ShowThumbnails", then we will get following effect if we open this file.
Pdf.ViewerPreferences.PageMode = PdfPageMode.UseThumbs;
Pdf.SaveToFile("ShowThumbnails.pdf");
