PDF Converter for PCL (LincPDF) Frequently Asked Questions
Q: LincPDF works fine in singlethread mode. In multithread mode with several threads processing conversion job, it randomly throws an exception from inside ConvertFile procedure. According to Lincoln documentation, LincPDF is multithread safe. Is it correct?
A: LincPDF is not multithreaded. Although the LPDFCtrl module is multi-threaded, LincPDF cannot be multi-threaded, because the LincJetX.dll module is not multi-threaded.
LincPDF uses a feature of Microsoft ActiveX control which happens to be only available for multi-threaded initialization. To satisfy the Microsoft ActiveX control, LPDFCtrl.dll must be initialized in a multi-threaded apartment.
Q: How can I make LincPDF watch a directory and convert files in it?
A: LincPDF does not have such a feature. However, you can make a batch file similar to the following, and make your own process which runs the batch file periodically. Or you can write your own directory-watching code to interface with LPDFctrl (see \Lincoln\Documents\LincPDF\LincPDFContrl.doc).
The following batch file (also attached) runs C:\Program Files\Lincoln\Bin\LincPDFC.exe to convert all PCL files in F:\Samples directory. The PDF is deposited in the same directory as the PCL, with the same filename.
for %%f in (F:\Samples\*.pcl) do call C:\Progra~1\Lincoln\Bin\LincPDFC -i%%f -o%%f.pdf
Q:The web page says it suports MOST soft fonts. Could you give some idea of what types of soft font it does not support ?
A:Only soft IntelliFont is not supported.
Q: It says that it produces searchable PDF which I take to mean that PCL text is left as text in the PDF.
Q: In what form do text & vectors in HP-GL/2 appear...
...in the PDF?
...in PCL soft fonts?
...as type 3 PDF bitmap fonts - 300 dpi only?
...in the 45 or so built-in PCL fonts ?
A: We support HP-GL/2 conversion. So all the text and vectors in HP-GL/2 will be the corresponding text and vectors description in PDF. PCL soft fonts will always be subset embedded in PDF, the type depends on what the PCL font type is. For TrueType, it will be TrueType in PDF. For bitmap font, it will be Type 3 font in PDF, including 300 dpi and 600 dpi. For standard PCL font (45 or built-in), user can choose subset embedded or not embedded. By the way, LincPDF supports Type 16 font and double bytes Asian font. This kind of font will be converted as CID-keyed font in PDF.
Q: Is the level of PDF it generates selectable - eg PDF 1.2 or PDF 1.3 ?
A: Not selectable. Only PDF 1.3.
Q: Can the Active-X COM object be used as a normal Windows DLL ?
A: Yes, you can.
