How to create PDF page based on image size 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 create a PDF page based on image size using C# and VB.NET.
Steps to create PDF page based on image size programmatically:
- Create a new C# console application project.
- Install the Syncfusion.Pdf.WinForms NuGet package as reference to your .NET Framework application from NuGet.org.
- Include the following namespaces in Program.cs file.
C#
using Syncfusion.Pdf; using Syncfusion.Pdf.Graphics; using System.Drawing;
VB.NET
Imports Syncfusion.Pdf Imports Syncfusion.Pdf.Graphics Imports System.Drawing
- Use the following code snippet to create a PDF page based on the image size.
C#
//Create a new PDF document
PdfDocument document = new PdfDocument();
//Load the image from the disk
PdfBitmap image = new PdfBitmap("Syncfusion.png");
//Add the first section to the PDF document
PdfSection section = document.Sections.Add();
//Initialize unit converter
PdfUnitConvertor converter = new PdfUnitConvertor();
//Convert image size from pixel to points
SizeF size = converter.ConvertFromPixels(image.PhysicalDimension, PdfGraphicsUnit.Pixel);
//Set section size based on the image size
section.PageSettings.Size = size;
// Set section orientation based on image size (by default Portrait)
if (image.Width > image.Height)
section.PageSettings.Orientation = PdfPageOrientation.Landscape;
//Set margin for section
section.PageSettings.Margins.All = 0;
//Add a page to the section
PdfPage page = section.Pages.Add();
//Draw image
page.Graphics.DrawImage(image, 0, 0);
//Save the document
document.Save("Sample.pdf");
//Closes the document
document.Close(true);
//This will open the PDF file so, the result will be seen in default PDF Viewer
Process.Start("Sample.pdf");
VB.NET
'Create a new PDF document
Dim document As New PdfDocument()
'Load the image from the disk
Dim image As New PdfBitmap("Syncfusion.png")
'Add the first section to the PDF document
Dim section As PdfSection = document.Sections.Add()
'Initialize unit converter
Dim converter As New PdfUnitConvertor()
'Convert image size from pixel to points
Dim size As SizeF = converter.ConvertFromPixels(image.PhysicalDimension,PdfGraphicsUnit.Pixel)
'Set section size based on the image size
section.PageSettings.Size = size
' Set section orientation based on image size (by default Portrait)
If image.Width > image.Height Then
section.PageSettings.Orientation = PdfPageOrientation.Landscape
End If
'Set margin for section
section.PageSettings.Margins.All = 0
'Add a page to the section
Dim page As PdfPage = section.Pages.Add()
'Draw image
page.Graphics.DrawImage(image, 0, 0)
'Save the document
document.Save("Sample.pdf")
'Closes the document
document.Close(True)
'This will open the PDF file so, the result will be seen in default PDF Viewer
Process.Start("Sample.pdf")
