The Syncfusion .NET Core PDF library is used to create, read, and edit PDF documents programatically without the dependency on Adobe Acrobat. Using this library, you can open and save PDF document on Mac OS.

Steps to open and save the PDF documents programmatically:

Step 1: Create a new .NET Core console application project.

Step 2: Select the project version.

Step 3: Install the Syncfusion.Pdf.Net.Core NuGet package as a reference to your project from 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 “Syncfusion.Licensing” assembly reference and include a license key in your projects. Please refer to this link to know about registering Syncfusion license key in your application to use our components.

Step 4: Include the following Namespaces in the Program.cs file.

C#

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

Step 5: Add the following code sample to the Program.cs file to open an existing PDF document in .NET Core application on Mac OS.

C#

//Open an existing PDF document.
FileStream document = new FileStream("Input.pdf", FileMode.Open, FileAccess.Read);
PdfLoadedDocument document = new PdfLoadedDocument(stream);

Step 6: Add the following code example to add paragraph and table to the PDF document.

C#

//Get the first page from a document.
PdfLoadedPage page = document.Pages[0] as PdfLoadedPage;
//Create PDF graphics for the page.
PdfGraphics graphics = page.Graphics;

//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(40, 400,page.Size.Width-80,0));

Step 7: Add the following code example to save the PDF document in the .NET Core application on Mac OS.

C#

//Create a FileStream to save the PDF document.
using(FileStream outputStream = new FileStream("Result.pdf", FileMode.Create, FileAccess.ReadWrite))
{
//Save the PDF file.
document.Save(outputStream);
}

A complete working sample can be downloaded from Github.

By executing the program, you will get the PDF document as follows.
