How to convert EMF to PDF using C# and VB.NET?
Syncfusion Essential PDF is a .NET PDF library used to create, read, and edit PDF documents. Using this library, you can convert EMF(Enhanced Metafile) to PDF or draw an EMF on the PDF page in C# and VB.NET.
On conversion, the EMF graphics will be transformed to the native PDF graphics that supports text selection and searching.
Steps to draw or convert EMF to PDF programmatically:
- Create a new C# console application project.
- Install the Syncfusion.Pdf.WinForms NuGet packages as reference to your .NET Framework application from NuGet.org.
- Include the following namespaces in the Program.cs file.
C#
using Syncfusion.Pdf; using Syncfusion.Pdf.Graphics;
VB.NET
Imports Syncfusion.Pdf Imports Syncfusion.Pdf.Graphics
- Use the following code snippet to create PDF and draw EMF on it.
C#
//Create a PDF Document
PdfDocument doc = new PdfDocument();
//Add pages to the document
PdfPage page = doc.Pages.Add();
//Create PDF graphics for the page
PdfGraphics graphics = page.Graphics;
//Create the layout format
PdfMetafileLayoutFormat format = new PdfMetafileLayoutFormat();
//Split text and image between pages
format.SplitImages = true;
format.SplitTextLines = true;
//Create a metafile instance
PdfMetafile metaChart = new PdfMetafile("MetaChart.emf");
//Draw the metafile in the page
metaChart.Draw(page, PointF.Empty, format);
//Save the document
doc.Save("EMFToPDF.pdf");
//Close the document
doc.Close(true);
//This will open the PDF file so, the result will be seen in default PDF viewer
Process.Start("EMFToPDF.pdf");
