# How can I generate a .pdf file from a .prc database?

Please use the following code fragment as a sample:

```
{
  // open .prc for read and write access
  OdStreamBufPtr pPrcStream = odrxSystemServices()->createFile("<span class="win-path">\\input.prc</span>", Oda::kFileRead, Oda::kShareDenyNo, Oda::kOpenExisting);

  // load special module
  OdPrcToPdfModulePtr pModule = ::odrxDynamicLinker()->loadModule(OdPrcToPdfModuleName, false);

  // create new .pdf file
  OdStreamBufPtr pPdf = odrxSystemServices()->createFile("<span class="win-path">\\output.pdf</span>", Oda::kFileWrite, Oda::kShareDenyNo, Oda::kCreateAlways);

  // insert .prc to .pdf with some default paper and 3D View parameters.
  OdResult res = pModule->prcToPdf(pPrcStream, pPdf);
  ODA_ASSERT(res == eOk);
}
```

You can use a more complicated version of the prcToPdf() method:

```
virtual OdResult prcToPdf(OdStreamBufPtr pPrcStream, OdStreamBufPtr pPdfStream, const OdGsPageParams &pdfParams, const OdGeMatrix3d &C2W, double CO, double OS);
```

For additional information about C2W, CO and OS parameters, please see the [Adobe® Portable Document Format specification](http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/pdf_reference_1-7.pdf).
