Unable to load PDFOptimize plugin

chavas · Post by **chavas** » Wed Dec 30, 2020 5:51 am

Hi,

I am using PDFXchange sdk with manifest files to OCR and Optimize pdf files in my service. I am loading two plugins for this- OCR and PDFOptimize. OCR plugin loads with out any problems but PDFOptimize plugin fails everytime. I have placed all the necessary files as far as I know. Here is the screenshot of my folder structure. I understand that I might be missing some files....but I don't know which ones. Can you have a look and tell me what is wrong?

Here is my code for loading the plugins- we are using VB.NET
Private Sub InitPDFControl(ByRef m_Inst As PDFXEdit.PXV_Inst, ByRef m_pxcInst As PDFXEdit.IPXC_Inst)
Try
Dim prefsPathStr As PDFXEdit.IString = Nothing
Dim licKey As String = mykey

Dim prefsPath As String = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) & "\DV\settings.dat"

m_Inst = New PDFXEdit.PXV_Inst()

If prefsPath.Length <> 0 Then
prefsPathStr = m_Inst.CreateString(prefsPath)
End If

m_Inst.Init(Nothing, licKey, prefsPathStr, Nothing, Nothing, 0, Nothing)

m_pxcInst = CType(m_Inst.GetExtension("PXC"), PDFXEdit.IPXC_Inst)

m_Inst.StartLoadingPlugins()
m_Inst.AddPluginFromFile(Application.StartupPath & "\Common\Plugins.x86\OCRPlugin.pvp")

m_Inst.AddPluginFromFile(Application.StartupPath & "\Common\Plugins.x86\PDFOptimizer.pvp")
m_Inst.FinishLoadingPlugins()

Catch ex As Exception
writelog(ex.ToString)
End Try
End Sub

Hello chavas,

Does it load correctly when you place the Plugins.x86 and PluginsData folder near the dll?
Also, does it load correctly in the simple program sample like FullDemo application?

Cheers,
Alex

Hi Alex,

If I place the Plugins.x86 and Plugin Data folder near the PDFXEditCore.x86.dll it still does not load PDFOptimize plugin. However OCR plugin loads correctly.

In my sample project where I am using the PDF editor control by registering the COM component, the PDF optimize plugin loads correctly. I have installed the SDK and your end-user PDF editor on my machine. So my guess is that I am missing some dependency files/folder in my service. I have copied all the files from my sample project to my final project (OCR and Optimize service). OCR works fine but Optimize plugin does not load.

Hi Alex,

My service is x86 build..does that make any difference? what is "PDFOptimizerx86.pvp" for?

Hello chavas,

Are you using the respective plugin folders from the End-User Editor, or only a part of the files inside?

Cheers,
Alex

Hi Charu.

We cannot reproduce your trouble with loading the PDFOptimizer.pvp. If problem is still actual for you - please try the latest 358 build and let us know about result. Also please note that version of main dll (PDFXEditCore.x86.dll) and PDFOptimizer.pvp should be identical to avoid any potential incompatibility. To see build version of PDFOptimizer.pvp - just rename extension to dll and look to its Properties/Details in WindowsExplorer.

Cheers.
