fancy Stream)

Error Handling
ɸ
DURING/HANDLER/ENDHANDLER
ɸ
In Acrobat itself, these map to 
something akin to setjmp/longjmp
Trying to mix them with C++ exceptions 
can be a problem.  
You can’t nest them!
ɸ
SPDF actually defines them as try/catch 
blocks

More on Error Handling
ɸ
Unfortunately, Acrobat does NOT 
always “throw”.  Sometimes you 
have to use other methods
ɸ
foo== NULL, PDxxxIsValid(), etc.
ɸ
CosNull != NULL
ɸ
If want a null CosObject, you can call 
CosNewNull() to get one.  BUT that 
should be treated as a valid object and 
NOT as NULL.

Thread Safety?
ɸ
Acrobat, nor the Adobe PDFLibrary, are 
thread safe!  As such, you should not try 
to use them in a threaded environment 
OR make your own threads outside the 
SDK.
ɸ
There are some exceptions to this rule if you 
are VERY careful, but you’re playing with fire.
ɸ
SPDF comes in both thread safe and non-
thread safe versions.
ɸ
If you know you don’t need threads, then why 
take the performance overhead!

Splitter Example (SDK)
PDFlib
What’s in there?
ɸ
PDF Creation/Generation
ɸ
Text, images, vectors, bookmarks, links, etc.
ɸ
Allows importing of pages from other PDF’s 
as “XObjects”with accompanying PDI library
ɸ
Accessible from C/C++, Java, Perl, PHP, etc. 
ɸ
Available as an ActiveX/COM component
ɸ
Available as platform-neutral C source
Everything is a PDF?
ɸ
You initialize PDFlib and get back a reference 
to an opaque “PDF”structure.
ɸ
PDF *p = PDF_new();
ɸ
Each “PDF”can have only a single PDF open 
at any one time for generation, BUT you can 
have as many “PDF”’s around as you want 
(eg. One per thread).
