The Syncfusion .NET PDF library is used to create, read, edit PDF documents programmatically without the dependency of Adobe Acrobat. Using this library, you can create PDF document in Azure Functions v4.

Steps to create a PDF document in Azure Functions v1

Step 1: Create a new Azure Functions project.

Step 2: Create a project name and select the location.

Step 3: Select function worker as .NET Framework.

Step 4: Install the Syncfusion.PDF.AspNet NuGet package as a reference to your project from NuGet.org.

NOTE

Starting with v16.2.0.x, if you reference Syncfusion assemblies from 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 Function1.cs file.

C#

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

Step 5: Add the following code example in Run method of Function1 class to perform create a PDF document in Azure Functions and return the resultant PDF document.

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.
var assembly = Assembly.GetExecutingAssembly();
var imageStream = assembly.GetManifestResourceStream("Create-PDF-document.Data.AdventureCycle.jpg");
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 sells metal and composite bicycles to North American, European and Asian commercial markets. While its base operation is located in Washington with 290 employees, several regional sales teams are located throughout their market base.";
//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));

//Save and close the PDF document  
MemoryStream ms = new MemoryStream();
document.Save(ms);
document.Close();
ms.Position = 0;

HttpResponseMessage response = new HttpResponseMessage(HttpStatusCode.OK);
response.Content = new ByteArrayContent(ms.ToArray());
response.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment")
{
    FileName = "Sample.pdf"
};
response.Content.Headers.ContentType = new System.Net.Http.Headers.MediaTypeHeaderValue("application/pdf");
return response;

Step 6: Right click the project and select Publish. Then, create a new profile in the Publish Window.

Step 7: Select the target as Azure and click Next button.

Step 8: Select the Create new button.
