PDF Export: Missing Graphics

Question

PDF Export: Missing Graphics<br /><br />Below is a section of code we are using to export a document as a PDF. The code will work 99% of the time, but occasionally we are getting the resulting PDF with some of the linked PDF components completely missing!<br /><br />The only way we have been able to reproduce this is (strangely) by continually opening and closing 'Windows Explorer' windows (We are using CS2 on XP), just as the process begins, until the final PDF is created.<br /><br />Our customer (who has hilighted the problem) would clearly not be doing this but we feel there is an issue here. (If the keyboard and mouse are left completely alone, the process is successful... 100% OF THE TIME!).<br /><br />The problem occurs both on site and at base, the linked PDF's are located on the LAN.<br /><br />The code snippet (with error checking taken out for brevity) is below:<br /><br />     UIDRef pageUIDRef = PCSImageUtils::GetFirstPageUIDRef();<br />     UIDList temp = ((UIDList)(pageUIDRef));     <br /><br />     ErrorCode status = kFailure;<br />     do<br />     {<br />          // obtain command boss<br />                InterfacePtr<ICommand> pdfExportCmd(CmdUtils::CreateCommand(kPDFExportCmdBoss));<br />          <br />          // set export prefs<br />          InterfacePtr<IPDFExportPrefs> pdfExportPrefs(pdfExportCmd, UseDefaultIID());<br />          InterfacePtr<IPDFExportPrefs> appExportPrefs((IPDFExportPrefs*)::QuerySessionPreferences(IID_IPDFEXPORTPREFS));<br />          pdfExportPrefs->CopyPrefs(appExportPrefs);<br /><br />          // set SysFileData<br />          PMString pmFilePath("C:\\Outputfile.PDF");<br />          IDFile sysFilePath(pmFilePath);<br />          InterfacePtr<ISysFileData> trgSysFileData(pdfExportCmd, IID_ISYSFILEDATA);<br />          trgSysFileData->Set(sysFilePath);<br />          <br />          // set UI flags<br />          InterfacePtr<IUIFlagData> uiFlagData(pdfExportCmd, IID_IUIFLAGDATA);<br />          uiFlagData->Set(kSuppressUI);<br />          <br />          // set UIDList containing pages to output (item list of command)<br />          UIDList theList(temp);<br />          pdfExportCmd->SetItemList(theList);<br />          <br />          // set UIDRefs containing pages to output (IOutputPages)<br />          InterfacePtr<IOutputPages> outputPages(pdfExportCmd, UseDefaultIID());<br />          outputPages->Clear();<br />          IDataBase* db = theList.GetDataBase();<br />          outputPages->SetMasterDataBase(db);<br />          int32 nProgressItems = theList.Length(); <br />          for (int32 index = 0 ; index < nProgressItems ; index++) <br />          {<br />                  outputPages->AppendUIDRef(theList.GetRef(index));<br />          }<br /><br />          // set PDF document name (get name from IDocument)<br />          InterfacePtr<IDocument> doc ((IDocument*)db->QueryInstance(db->GetRootUID(), IID_IDOCUMENT));<br />          PMString documentName; <br />          doc->GetName(documentName);<br />          outputPages->SetName(documentName);<br />          <br />          // finally process command<br />          status = CmdUtils::ProcessCommand(pdfExportCmd);<br />     } while(false);<br /><br />Thanks in advance.<br /><br />Dave Wilson.

Hi Dave,
It looks like a problem with unsafe threads inside command ...
Did you tried set some preferences from next ?
SetPDFExOmitPDF( kExportOmitPDFOFF )
SetPDFExOmitBitmapImages ( kExportOmitBitmapImagesOFF )
may be help you stabilize export process ...
