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.

C#

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.

C#

//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

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

C#

dotnet 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.
