I want to show a method to extract image from PDF by using VB.NET via Spire.PDF.please download Spire.PDF dll for this.

Imports System
Imports System.Collections.Generic
Imports System.Drawing
Imports System.Drawing.Imaging
Imports Spire.Pdf

Namespace ExtractImage
Friend Class Extract
Shared Sub Main(ByVal args() As String)
'Load File
Dim doc As New PdfDocument()
doc.LoadFromFile("D:\work\My Documents\Employee Information.pdf")

Dim images As IList(Of Image) = New List(Of Image)()

For Each page As PdfPageBase In doc.Pages
For Each image As Image In page.ExtractImages()
images.Add(image)
Next image
Next page

doc.Close()

'Save Image
Dim index As Integer = 0
For Each image As Image In images
Dim imageFileName As StringString = String.Format("Extract{0}.png", index)
index += 1
image.Save(imageFileName, ImageFormat.Png)
Next image

System.Diagnostics.Process.Start("Extract0.png")
End Sub
End Class
End Namespace

Solution 3

Do you need extract the images to PDF or another image format?
If it is to PDF just use ITextSharp or PDFSharp.
If you need to rasterize you have this http://code.google.com/p/mupdf-converter/[^]

Solution 5

MigraDoc + PDFSharp can do that.
http://www.pdfsharp.net/wiki/ExportImages-sample.ashx[^]

The library is free, you can use it in open source and closed source applications. It also can be found in NuGet packages inside Visual Studio.
