Using the PDFlib generator
No drivers need to be installed in order to use the PDFlib
generator to save DataWindow data as a native PDF file.
The DLL file for PDFlib (PBPDF.dll) is automatically packaged into
the PowerBuilder application executable without requiring the developer
to make any configuration or selection during the building
process.
By using the PDFlib generator, the DataWindow is first saved to
EMF. Depending on the size of the DataWindow and also the specified page
size, there may be multiple EMFs. For example, if a DataWindow has 8
columns that cannot fit in a page, maybe the first 3 columns are in page
#1, and the other 5 columns in page #2; if the DataWindow has more data,
and the data will go to page #3 (and page #4), page #5 (and page #6),
and so on. The EMF files will then be converted and combined into one
PDF. The EMF files are memory-based and will be deleted from memory
after the successful generation of the PDF file.
During the PDF generation process, an “Appeon” folder (containing
a “NativePDF” sub-folder which contains a “Log” and a “Temp”
sub-folders) will be generated in the temporary directory; the temporary
files in these folders will be deleted after the PDF file is created but
the folders will be kept for future use.
For how to set PDFLib as the default PDF method and the other
properties, see the section called “Saving as PDF using NativePDF! method with PDFlib” in Users Guide.
