Linearization is the creating of a file that is "Fast Web View" enabled - it has nothing to do with file size reduction.

You can use Acrobat's own PDF Optimizer via Acrobat's Batch feature all by itself - no scripting is necessary.

Also, you can only use Linearized if you use PDSaveFull, and there are
other flags which you could usefully add.

Dear all,

I am new to Acrobat and I am searching to compress PDF files too, for example by reducing quality level and using Jpeg2000 instead of Jpeg compression. I have read the suggestion below :

"You can use Acrobat's own PDF Optimizer via Acrobat's Batch feature all by itself - no scripting is necessary."

I wonder where this Acrobat's Batch feature could be found and in which document it is described. I also wonder if it is possible to call it as an external application from a VB6 program (with a Shell call), writing the save options like Jpeg2000 compression as parameters in a command line.

Best Regards,

Hi Aandi,

Thank you for your answer.

I created a batch sequence that saves and compresses a file. I finally noticed that Jpeg compression generates a smaller file (but with a worse quality) than with Jpeg2000.

Now I wonder what would be the best way to compress a PDF file automatically :

- using API like AVDocSaveOptimized function (seen in acrobat_pdfl_api_reference.pdf file) in C/C++ ;

- using API like AVDocSaveOptimized in VB6 (it does not seem to be possible because I did not found this function in the Adobe Acrobat 8 Type Library) ;

- using API to open a file in Acrobat Pro and launch the batch sequence (if it is possible) ;

- using another solution ?

Hi Leonard,

Thank you for your answer.

There are just 2 points that are still unclear for me :

- is it possible to call an Acrobat plug-in from a VB6 program ? (I saw that a plug-in is an .api file rather than a .dll)

- do PDF Optimizer functions like AVDocSaveOptimized can be called from a C/C++ standalone application ?

Best Regards,

Hi I am reading the PDF files programmatically using C# , here I am suffering from the reading order in PDF files, as at the some places its column wise and some places its plain text read in line.

I want to know if there is any the solution for the making the reading order correct in PDF files (it should be left to right and Top to bottom).

Touchup text tool makes this task. Does anybody know how to get the touch up tools functionality though program using c# or VB.net?

I'm lost on this, as well. How, programmatically, do you optimize? I will be running this process as an automated service, so menu items would be out of the question. It will be a .net windows service that scans a directory, appends the PDFs and optimizes them. How do I go about doing this?

how do you automate menu items if not through the SDK? the CreateObject call invokes Acrobat.exe...

I tried this:
Dim outDoc As CAcroPDDoc
Dim App As CAcroApp
Dim inDoc As CAcroPDDoc
Dim outputFileFullPath As String
Dim inputFileName As String
Dim i As Integer
'Dim fileNames(PDFfiles.Count - 1) As String
Dim xmlFileName As String
Dim w As String, x As String, y As String, z As String
Dim numInPages As Integer, numOutPages
Dim retval As Integer
Dim tempFileName As String
Dim xmlFile As String
Dim processAcrobat() As Process
Dim trialAttempts As Integer = 6
Dim triedAttempts As Integer
Dim finishedOptimization As Boolean
Dim killedAcrobat As Boolean
Dim BRetval As Boolean = False
Dim AcrobatJava As Object
'Dim pp As VariantType

'For i = 0 To PDFfiles.Count - 1
' fileNames(i) = PDFfiles(i)
'Next i
If PDFfiles.Count = 0 Then
'FileSet.LogMessage("No files were found for this set. Output File was going to be " & outputFileName)
Exit Function
End If
tempFileName = Path.Combine(outputDir, "temp.pdf")

If PDFfiles.Count > 1 Then
Try
'outDoc.New(outputFileFullPath)
outDoc = CreateObject("AcroExch.PDDoc")
App = CreateObject("AcroExch.App")
App.Hide()
'outDoc.Open(outputFileName)
File.Copy(PDFfiles(0), PDFfiles(0) + ".tmp", True)
outDoc.Open(PDFfiles(0) + ".tmp")
For i = 1 To PDFfiles.Count - 1
inDoc = CreateObject("AcroExch.PDDoc")
inputFileName = PDFfiles(i)
retval = inDoc.Open(inputFileName)
'outDoc.Attach(inDoc)
'outDoc.InputCopyAll()
numOutPages = outDoc.GetNumPages() - 1
numInPages = inDoc.GetNumPages()

retval = outDoc.InsertPages(numOutPages, inDoc, 0, numInPages, -1)
numOutPages = outDoc.GetNumPages()

inDoc.Close()
inDoc = Nothing
'File.Copy(inputFileName, outputDir & "/" & CStr(i) & ".pdf")
Next i

'outDoc.Close()
AcrobatJava = outDoc.GetJSObject()

App.Hide()
Dim pp As Object = AcrobatJava.getPrintParams()
pp.fileName = "file://c/ftp_stream/example/myDoc.ps"
pp.printerName = ""
AcrobatJava.print(pp)
'App.Show()
'App = Nothing
AcrobatJava = Nothing
outDoc.Save(Acrobat.PDSaveFlags.PDSaveFull + Acrobat.PDSaveFlags.PDSaveCollectGarbage + Acrobat.PDSaveFlags.PDSaveLinearized, Path.Combine(outputDir, outputFileName)) 'Path.Combine(outputDir, "final.pdf"))

outDoc.Close()
outDoc = Nothing
BRetval = True
Catch ex As Exception
'FileSet.LogMessage("Error Message 1007: Error concatenating Pdf Files for inputfile " & inputFileName & " OutputFile=" & outputFileName & " Error is " & Err.Description)
BRetval = False
Finally
outDoc = Nothing
Do Until killedAcrobat Or triedAttempts = trialAttempts
Try
processAcrobat = System.Diagnostics.Process.GetProcessesByName("Acrobat")
For i = 0 To processAcrobat.GetLength(0) - 1
processAcrobat(i).Kill()
Next
triedAttempts = triedAttempts + 1
If File.Exists(inputFileName + ".temp") Then
File.Delete(inputFileName + ".temp")
System.Threading.Thread.Sleep(1000)
End If
killedAcrobat = True
Catch exException As Exception
killedAcrobat = False
End Try
Loop
End Try
Else
File.Copy(PDFfiles(0), outputFileName, True)
End If

When I get to "getPrintParams" it pops up a dialogue window. How do I get it to not do that?

please provide a sample in c++ of how to call AVDocSaveOptimized specifying the header files, references, settings...
thanks

In adobe there is a function by which you can right click on a group of files, and choose to concatenate them, with a menu option for making the file size smaller. I have tried to scour the documentation for a way to automate this, and have found nothing. Is this at all possible through the SDK?

What's odd is I found a way to combine the PDFs, then save as postscript then distill, but it takes 12 hours, mostly the PDF conversion. the combine and shrink takes about 5. I essentialyl just need a way to shrink the PDF without making postscript of it.
