Pdf Extract Text and Image

[lfcnutter]

Hi,
I'm using the sample vb.net demo to extract text and images from pdf files.
However some of my pdf's do not contain images so the program throws an exception at the next statement

How do I check for the condition and prevent the exception

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

regards

Hello,

Thanks for your inquiry and sorry for the late reply as weekend.
Please refer to the below code to extract images from PDF documents. If there is any question, please provide your input file for further investigation.

Code: Select all

        Dim doc As PdfDocument = New PdfDocument
        'Load a PDF file
        doc.LoadFromFile("test.pdf")
        Dim ListImage As List(Of Image) = New List(Of Image)
        Dim i As Integer = 0
        Do While (i < doc.Pages.Count)
            ' Get an object of Spire.Pdf.PdfPageBase
            Dim page As PdfPageBase = doc.Pages(i)
            ' Extract images from Spire.Pdf.PdfPageBase
            Dim images() As Image = page.ExtractImages
            If ((Not (images) Is Nothing) AndAlso (images.Length > 0)) Then
                ListImage.AddRange(images)
            End If
            i = (i + 1)
        Loop

        If (ListImage.Count > 0) Then
            Dim j As Integer = 0
            Do While (j < ListImage.Count)
                Dim image As Image = ListImage(j)
                image.Save(String.Format("image-{0}.png", (j + 1)), ImageFormat.Png)
                j = (j + 1)
            Loop

        End If
