1.18 DLI Implementation and Reference Guide
Functions Updated
dlpdfinit
This has been revised significantly, and now requires three parameters:
• the PDFLData pointer containing Adobe PDF Library initialization data
• the default file system to use, or NULL for the Adobe PDF Library default filesystem
• NULL; reserved for future use as an optional argument
The DLI graphics cache has been enhanced to use the default ASFileSys
implementation provided to dlpdfinit for caching graphics. By default, the
graphics cache file size is limited to 1.5GB. Customers who wish to use larger graphics
cache files are advised to supply a filesystem to dlpdfinit which is capable of
reliably handling files of the larger size.
dlpdfdoccreate
This call no longer accepts a PostScript filename. (Use dlpdfdocsetpsname, or
supply one to dlpdfdocwritePS.) The PDFNeeded flag has been removed; PDF
processing is always performed. It accepts one parameter, the DLPDFINSTANCE to use
for the document.
dlpdfterm
This call now removes memory files used for the dlpdfttload call if the Files In
Memory system is used, and if these files are no longer in use.
Functions Removed
dlpdfdocsevenbitsafe
This method was not able to guarantee a PDF output stream safe for a seven-bit
channel. The PDF specification refers to PDF as a binary format, and expects that
consumers are able to accept a binary input stream.
