The Syncfusion .NET Core PDF library is used to create, read, and edit PDF documents programmatically without the dependency on Adobe Acrobat. Using this library, you can create a PDF document in ASP.NET Core application on Linux.

Steps to create PDF document programmatically

Step 1: Execute the following command in the Linux terminal to create a new .NET Core Console application project.

  • C#
  • dotnet new console

    Step 2: Install the Syncfusion.Pdf.Net.Core NuGet package as a reference to your project from NuGet.org by executing the following command.

  • C#
  • dotnet add package Syncfusion.Pdf.Net.Core -v xx.x.x.xx -s https://www.nuget.org/

    NOTE

    Starting with v16.2.0.x, if you reference Syncfusion assemblies from the trial setup or from the NuGet feed, you also have to add the “Syncfusion.Licensing” assembly reference and include a license key in your projects. Please refer to this link to know about registering the Syncfusion license key in your application to use our components.

    Step 3: Include the following Namespaces in the Program.cs file.

    using Syncfusion.Pdf;
    using Syncfusion.Pdf.Graphics;
    using Syncfusion.Drawing;
    using System.IO;

    Step 4: Add the following code sample to the Program.cs file to create a PDF document in the .NET Core application on Linux.

    //Create a new PDF document.
    PdfDocument document = new PdfDocument();
    // Set the page size.
    document.PageSettings.Size = PdfPageSize.A4;
    //Add a page to the document.
    PdfPage page = document.Pages.Add();
    
    //Create PDF graphics for the page.
    PdfGraphics graphics = page.Graphics;
    //Load the image from the disk.
    FileStream imageStream = new FileStream("AdventureCycle.jpg", FileMode.Open, FileAccess.Read);
    PdfBitmap image = new PdfBitmap(imageStream);
    //Draw an image.
    graphics.DrawImage(image, new RectangleF(130,0, 250, 100));
    
    //Draw header text. 
    graphics.DrawString("Adventure Works Cycles", new PdfStandardFont(PdfFontFamily.TimesRoman, 20, PdfFontStyle.Bold), PdfBrushes.Gray, new PointF(150, 150));
    
    //Add paragraph. 
    string text = "Adventure Works Cycles, the fictitious company on which the AdventureWorks sample databases are based, is a large, multinational manufacturing company. The company manufactures and sel
    //Create a text element with the text and font.
    PdfTextElement textElement = new PdfTextElement(text, new PdfStandardFont(PdfFontFamily.TimesRoman, 12));
    //Draw the text in the first column.
    textElement.Draw(page, new RectangleF(0, 200, page.GetClientSize().Width, page.GetClientSize().Height));
    
    //Create a PdfGrid.
    PdfGrid pdfGrid = new PdfGrid();
    //Add values to the list.
    List<object> data = new List<object>();
    Object row1 = new { Product_ID = "1001", Product_Name = "Bicycle", Price = "10,000" };
    Object row2 = new { Product_ID = "1002", Product_Name = "Head Light", Price = "3,000" };
    Object row3 = new { Product_ID = "1003", Product_Name = "Break wire", Price = "1,500" };
    data.Add(row1);
    data.Add(row2);
    data.Add(row3);
    //Add list to IEnumerable.
    IEnumerable<object> dataTable = data;
    //Assign data source.
    pdfGrid.DataSource = dataTable;
    //Apply built-in table style.
    pdfGrid.ApplyBuiltinStyle(PdfGridBuiltinStyle.GridTable4Accent3);
    //Draw the grid to the page of PDF document.
    pdfGrid.Draw(graphics, new RectangleF(0, 300, page.Size.Width - 80, 0));
    
    //Create file stream.
    using (FileStream outputFileStream = new FileStream(Path.GetFullPath(@"Output.pdf"), FileMode.Create, FileAccess.ReadWrite))
    {
        //Save the PDF document to file stream.
        document.Save(outputFileStream);
    }

    Step 5: Execute the following command to restore the NuGet packages.

  • C#
  • dotnet restore

    Linux Build

    Step 6: Execute the following command in terminal to run the application.

  • C#
  • dotnet run

    Linux Run

    A complete working sample can be downloaded from Github.

    By executing the program, you will get the PDF document as follows. The output will be saved in parallel to program.cs file.
