Post subject:  "Insufficient Data" in Adobe Reader
I am using the GDI+ assemblies 1_31 and Migradoc to create PDF's from multiple TIFF files. I can view the PDF fine in other readers like PDF Complete and Nuance. If the PDF is opened in Adobe Reader X, they get an "Insuficient Data for an image" message and none of the pages below are visible.

I read two different forum messages about this issue:
1) stated they used the GDI+ and it was fixed but I am already using that
2) stated they had to save each tiff as a seperate PDF page and them combine into a single PDF

Hoping someone out there has a better suggestion. Please?

Below is the code I am using. I uncompress a zip file. Pull an *.asc file and open it. That doc tells me what TIFF images belong in each grouping (single PDF file).

Code:
   
Imports MigraDoc.Rendering
Imports MigraDoc.DocumentObjectModel
Imports MigraDoc.RtfRendering
Imports ICSharpCode.SharpZipLib.Zip

Function ProcessIndexFile(ByVal myFileName As String, ByVal myFilePath As String) As Boolean
        Dim sFileReader As System.IO.StreamReader
        Dim sInputLine As String
        Dim sWholeLine As String
        Dim sDate As String
        Dim sControl As String
        Dim sRteNum As String
        Dim sDocNum As String
        Dim sImgFileName As String
        Dim hDocNum As String
        Dim hDate As String
        Dim hRteNum As String
        Dim fStart, fNewDoc As Boolean
        Dim myerr As String

        Dim myDoc As Document
        Dim myRend As PdfDocumentRenderer
        Dim mySec As Section
        Dim myImg As MigraDoc.DocumentObjectModel.Shapes.Image
        Dim myPS As MigraDoc.DocumentObjectModel.Orientation

        fStart = True
        fNewDoc = True
        myPS = Orientation.Landscape

        On Error GoTo errorhandler

        sFileReader = System.IO.File.OpenText(myFileName)   '*****Open File
        sInputLine = sFileReader.ReadLine
        Do Until sInputLine Is Nothing              '*****Loop Line by Line through file
            sWholeLine = sInputLine                 '*****Create variable to store line

            '******************************************************
            '*****Pull field values from line based on position
            '******************************************************
            sDate = Mid(sWholeLine, 1, 8)
            sDate = Replace(sDate, "/", "")
            sControl = Mid(sWholeLine, 18, 14)
            sRteNum = Mid(sWholeLine, 18, 6)
            sDocNum = Mid(sWholeLine, 29, 3)
            sImgFileName = Mid(sWholeLine, 63, 12)
            Debug.Print(sDate & Chr(9) & sControl & Chr(9) & sDocNum & Chr(9) & sImgFileName)

            If fStart = True Then                   '*****Sets comp for first line of file
                hRteNum = sRteNum
                hDocNum = sDocNum
                hDate = sDate
                fStart = False
            End If

            If sDocNum <> hDocNum Then
                '*****Document changed, write previous file and start new one
                MigraDoc.DocumentObjectModel.IO.DdlWriter.WriteToFile(myDoc, "MigraDoc.mdddl")
                myRend = New PdfDocumentRenderer(True, PdfSharp.Pdf.PdfFontEmbedding.Always)
                myRend.Document = myDoc
                myRend.RenderDocument()
                myRend.PdfDocument.Save("c:\Me\processed\Me_" & hDate & "_" & hRteNum & "_" & hDocNum & ".pdf")

                hDocNum = sDocNum
                fNewDoc = True
            End If

            If fNewDoc = True Then
                myDoc = New Document
                myDoc.Info.Title = "Process Documents"
                myDoc.Info.Subject = sControl
                myDoc.Info.Author = "Me"
                fNewDoc = False
            End If

            mySec = myDoc.AddSection
            myImg = mySec.AddImage(myFilePath & "\" & sImgFileName)
            myImg.LockAspectRatio = True
            myImg.Width = New Unit(7, UnitType.Inch)

            'mySec.AddPageBreak()

            sInputLine = sFileReader.ReadLine       '*****Go to next line in file
        Loop
        sFileReader.Close()
        ProcessIndexFile = True
        Exit Function

errorhandler:
        myerr = "This file did not parse correctly.  Please contact Me with error code and copy of zip file." & Chr(13) & Chr(13)
        MsgBox(myerr & Err.Number & ": " & Err.Description)
        Debug.Print(Err.Number & " - " & Err.Description & ": " & Err.Source)
        ProcessIndexFile = False

    End Function

We call Windows routines to read TIFF files. Different Windows versions cause different problems with certain images.

It could be an error in PDFsharp that occurs with special image formats. If that's the case then we need such an image to fix the problem.

We don't know your Windows version and we don't have your TIFF files.
If it runs under XP and fails under Vista or W7 (creating the PDF files, not viewing), then blame Windows.

I don't recall what 1) refers to, but 2) was a problem with Windows accessing page 2 of a 3-page TIFF file. Page 1 was shown correctly.

Thomas,

Thanks for the quick response. Sorry, I didn't think to provide OS type info.

Running Windows 7, 64 bit on all computers.

As far as the image goes, I can not email it due to legal restrictions (contains client personal information). But, I can provide this level of detail about the image. I hope this is what you are looking for.
Authors: 1996-98 Accusoft Inc
Program Name: ImageGear Version 10.00....
Dimensions: 1695 x 1610
Hor/Ver Res is 200 dpi
Bit depth 1
compression is CCITT T.6
Res Unit is 2

Not all the PDF's created fail. PDF's with only 3-4 images are readable. If I go over that, some fail around the 4th image. I can see the first three images fine then no images after that.

My bosses asked that I program the app to create an individual pdf per image and then combined into a single PDF to see if that solved the issue. I don't see how that will work, but I am doing it. Really want it to work the other way so any assistance would be greatly apreciated.

Douglas

PS - I just found one of the images sent was a scan of a back page that was blank. I am allowed to send that one so I am attaching.

Douglas,

I cannot replicate the problem with the TIFF file you provided.
I include my PDF files (tested with Acrobat 8 and Reader X, no problems).

You can send files via e-mail. Maybe you can find pages that allow to replicate the problem without containing confidential data, so that you can send us the TIFFs and the PDF.

Thomas,

I just finished the code modifications to the above that creates a seperate PDF per Tiff and stores in a temp directory as 1.pdf, 2.pdf, etc. It uses the exact same creation of the PDF as above with MigraDoc. I then used PDFSharp to build a single PDF from those PDF's.

Amazingly enough, it works. All the PDF's that failed when I just use MigraDoc, now work perfectly in Adobe after using PDFSharp. I can only assume that PDFSharp is using a method that Windows 7 and Adobe likes better.

Because this was not a fun process and we should save others some of the hassel, I modified tiff's to remove customer specific data on one of the strings that created a bad PDF (one Adobe would not open). Even though I modified the files, would still not like to post on a forum. Can I email to you? If yes, how?

Thx,
Douglas

Thomas,

Spoke too soon. The first zip which had one failure, no longer failed. When I processed the second zip that had five failures, it now has only three. So this process helps but is not a cure-all. I still need your help.

Hi, Douglas,

I can replicate the error using the WPF build - no problem using the GDI+ build.

If I create a document with d5224700.003 and r5224700.004, the latter will not show.
If I create a document with r5224700.004 only, everything works fine.

Mysterious.
To make it more mysterious, you report that you already use the GDI+ build. I hope this is just a simple problem, but it won't be easy to find.

As a workaround, you can change the class PdfImage (in PdfImage.cs).
Search for
Code:
if (isFaxEncoding &&
  (imageDataFax.Length < imageDataCompressed.Length ||
  imageDataFaxCompressed.Length < imageDataCompressed.Length))

and replace it with (added " * 999")
Code:
#if false
        if (isFaxEncoding &&
          (imageDataFax.Length < imageDataCompressed.Length ||
          imageDataFaxCompressed.Length < imageDataCompressed.Length))
#else
        if (isFaxEncoding &&
          (imageDataFax.Length * 999 < imageDataCompressed.Length ||
          imageDataFaxCompressed.Length * 999 < imageDataCompressed.Length))
#endif

This will lead to bigger PDF files, but should avoid the insufficient data error.

Thomas,

You are the man! I modified the code as you suggested above. Compiled new DDL's. Ran 20 days of files creating over 270 PDF's. I opened every last one of them in Acrobat and no errors.

I owe you a pint for this one. I'll be in London in about a week if you happen to be in the area and want to collect.

Thx,
Douglas

Hi Thomas
when you say "should avoid the insufficient data error" does that mean that PDFSharp will ignore that tiff file and move on, or it will still include that tiff file.

In My case when I create pdf file through PDFSharp there are some instances where in i get "insufficient image data error" but when I process the same set of files again it creates the PDF file correct without any error.

Can you explain why is it happening.

Thanks..

The image will be included, but a different compression scheme will be used (thus bypassing the buggy compression scheme).

Or try the bug fix shown here:

Thanks Thomas,

The last release that happened was on "Mar 7, 2012" and the thread started on around " Nov 07, 2011". Has the bug fix not released on Mar 7 release. Correct me if I am wrong.
