CHAPTER 0. Preliminaries
Cpdf.startup
Initialises the library. Must be called before any other function.
Cpdf.version
Returns a string giving the version number of the CPDF library.
Cpdf.setFast
Some operations have a fast mode. The default is 'slow' mode, which works even
on old-fashioned files. For more details, see section 1.13 of the CPDF manual.
This function sets the mode to fast globally.

CHAPTER 1. Basics
Cpdf.fromFile(String, String)
Loads a PDF file from a given file. Supply a user password (possibly blank) in
case the file is encrypted. It won't be decrypted, but sometimes the password
is needed just to load the file.
Cpdf.fromFileLazy(String, String)
Loads a PDF from a file, doing only minimal parsing. The objects will be read
and parsed when they are actually needed. Use this when the whole file won't be
required. Also supply a user password (possibly blank) in case the file is
encrypted. It won't be decrypted, but sometimes the password is needed just to
load the file.
Cpdf.fromMemory(Byte[], String)
Loads a file from memory given any user password.
Cpdf.fromMemoryLazy(IntPtr, Int32, String)
Loads a file from memory, given a pointer and a length, and the user password,
but lazily like fromFileLazy. The caller must use AllocHGlobal / Marshal.Copy /
FreeHGlobal itself. It must not free the memory until the PDF is also gone.
Cpdf.startEnumeratePDFs
Cpdf.enumeratePDFsKey(Int32)
Cpdf.enumeratePDFsInfo(Int32)
Cpdf.endEnumeratePDFs
To enumerate the list of currently allocated PDFs, call startEnumeratePDFs
which gives the number, n, of PDFs allocated, then enumeratePDFsInfo and
enumeratePDFsKey with index numbers from 0...(n - 1). Call endEnumeratePDFs to
clean up.
Cpdf.ptOfCm(Double)
Converts a figure in centimetres to points (72 points to 1 inch)
Cpdf.ptOfMm(Double)
Converts a figure in millimetres to points (72 points to 1 inch)
Cpdf.ptOfIn(Double)
Converts a figure in inches to points (72 points to 1 inch)
Cpdf.cmOfPt(Double)
Converts a figure in points to centimetres (72 points to 1 inch)
Cpdf.mmOfPt(Double)
Converts a figure in points to millimetres (72 points to 1 inch)
Cpdf.inOfPt(Double)
Converts a figure in points to inches (72 points to 1 inch)
Cpdf.parsePagespec(Cpdf.Pdf, String)
Parses a page specification with reference to a given PDF (the PDF is supplied
so that page ranges which reference pages which do not exist are rejected).
Cpdf.validatePagespec(String)
Validates a page specification so far as is possible in the absence of the
actual document. Result is true if valid.
Cpdf.stringOfPagespec(Cpdf.Pdf, List{Int32})
Builds a page specification from a page range. For example, the range
containing 1, 2, 3, 6, 7, 8 in a document of 8 pages might yield "1-3, 6-end"
Cpdf.blankRange
Creates a range with no pages in.
Cpdf.range(Int32, Int32)
Builds a range from one page to another inclusive. For example, range(3, 7)
gives the range 3, 4, 5, 6, 7
Cpdf.all(Cpdf.Pdf)
The range containing all the pages in a given document.
Cpdf.even(List{Int32})
Makes a range which contains just the even pages of another range.
Cpdf.odd(List{Int32})
Makes a range which contains just the odd pages of another range.
Cpdf.rangeUnion(List{Int32}, List{Int32})
Makes the union of two ranges giving a range containing the pages in range a
and range b.
Cpdf.difference(List{Int32}, List{Int32})
Makes the difference of two ranges, giving a range containing all the pages in
a except for those which are also in b.
Cpdf.removeDuplicates(List{Int32})
Deduplicates a range, making a new one.
Cpdf.rangeLength(List{Int32})
Gives the number of pages in a range.
Cpdf.rangeGet(List{Int32}, Int32)
Gets the page number at position n in a range,
where n runs from 0 to rangeLength - 1.

Adds the page to a range, if it is not already
there.
Cpdf.isInRange(List{Int32}, Int32)
Returns true if the page is in the range,
false otherwise.
Cpdf.pages(Cpdf.Pdf)
Returns the number of pages in a PDF.
Cpdf.pagesFast(String, String)
Returns the number of pages in a given PDF, with given user password. It tries
to do this as fast as possible, without loading the whole file.
Cpdf.toFile(Cpdf.Pdf, String, Boolean, Boolean)
Writes the file to a given filename. If linearize is true, it will be
linearized if a linearizer is available. If make_id is true, it will be given a
new ID.
Cpdf.toFileExt(Cpdf.Pdf, String, Boolean, Boolean, Boolean, Boolean, Boolean)
Writes the file to a given filename. If make_id is true, it will be given a new
ID. If preserve_objstm is true, existing object streams will be preserved. If
generate_objstm is true, object streams will be generated even if not
originally present. If compress_objstm is true, object streams will be
compressed (what we usually want). WARNING: the pdf argument will be invalid
after this call, and should be not be used again.
Cpdf.toMemory(Cpdf.Pdf, Boolean, Boolean)
Writes a PDF file and returns as an array of bytes.
Cpdf.isEncrypted(Cpdf.Pdf)
Returns true if a documented is encrypted, false otherwise.

CHAPTER 2. Merging and Splitting
Cpdf.mergeSimple(List{Cpdf.Pdf})
Given a list of PDFs, merges the files into a new one, which is returned.
Cpdf.merge(List{Cpdf.Pdf}, Boolean, Boolean)
Merges the PDFs. If retain_numbering is true page labels are not rewritten. If
remove_duplicate_fonts is true, duplicate fonts are merged. This is useful when
the source documents for merging originate from the same source.
Cpdf.mergeSame(List{Cpdf.Pdf}, Boolean, Boolean, List{List{Int32}})
The same as merge, except that it has an additional argument - a list of page
ranges. This is used to select the pages to pick from each PDF. This avoids
duplication of information when multiple discrete parts of a source PDF are
included.

CPDF .NET Library
=================
Before using the library, you must make sure your project or build environment
has access to the cpdf DLL, which is not part of the .NET assembly. You can add
it to a Visual Studio project as a file, set to copy-to-output-folder. Or, you
can install it in a standard location. The DLL must be named as follows, for
.NET to be able to find it:
Windows: cpdf.dll
MacOS: libcpdf.dylib
Linux: libcpdf.so
The following documentation is automatically extracted from the XML comments
present in the assembly. You can use Intellisense to view them within Visual
Studio - the documentation here is for completeness.
A 'range' is a list of integers specifying page numbers.
Text arguments and results are in UTF8. Data is of type bytes[].
Any function may raise the exception CPDFError, carrying a string describing
the error.
There is no automatic garbage collection of PDFs. Use the Using keyword and/or
the Dispose method on objects of type Cpdf.Pdf to explicitly deallocate PDFs.
