Jay Berkenbilt 4a1cce0a47 Reimplement name and number tree object helpers 
Create a computationally and memory efficient implementation of name
and number trees that does binary searches as intended by the data
structure rather than loading into a map, which can use a great deal
of memory and can be very slow.

Jay Berkenbilt 39bfa01307 Implement user-provided stream filters

Jay Berkenbilt 2e7ee23bf6 Add QPDFPageDocumentHelper and QPDFPageObjectHelper 
This is the beginning of higher-level API support using helper
classes. The goal is to be able to add more helpers without continuing
to pollute QPDF's and QPDFObjectHandle's public interfaces.

Jay Berkenbilt 9910104442 Implement TokenFilter and refactor Pl_QPDFTokenizer 
Implement a TokenFilter class and refactor Pl_QPDFTokenizer to use a
TokenFilter class called ContentNormalizer. Pl_QPDFTokenizer is now a
general filter that passes data through a TokenFilter.

Jay Berkenbilt f02c5f5e12 Final preparation for 4.1.0 release 2013-04-14 15:03:51 -04:00
Jay Berkenbilt bfda717749 Cosmetic changes to be closer to Adobe terminology 
Change object type Keyword to Operator, and place the order of the
object types in object_type_e in the same order as they are mentioned
in the PDF specification.

Note that this change only breaks backward compatibility with code
that has not yet been released.
 2013-01-23 09:38:05 -05:00
Jay Berkenbilt 1d88955fa6 Added new QPDFObjectHandle types Keyword and InlineImage 
These object types are to facilitate content stream parsing.

Jay Berkenbilt 8708fd373d Prepare 4.0.1 release 2013-01-17 09:51:04 -05:00
Jay Berkenbilt 0ea70e5dae Update shared library major version to 10 
The upcoming 3.1 release contains non-compatible API changes, though
they only affect parts of the interface that are extremely unlikely to
have been used outside of qpdf itself.  The methods and data types
affected were used for communication between QPDFWriter and QPDF and
would have had no real use in end user code.

Jay Berkenbilt 0873e42300 SHA2 pipeline with support for 256, 384, and 512 bits 
Implemented pipeline around sph sha calls using standard test vectors
for full-byte values.  Did not test or support partial byte values.
 2012-12-31 05:36:51 -05:00
Jay Berkenbilt c9da66a018 Incorporate sha2 code from sphlib 3.0 
Changes from upstream are limited to change #include paths so that I
can place header files and included "c" files in a subdirectory.  I
didn't keep the unit tests from sphlib but instead verified them by
running them manually.  I will implement the same tests using the
Pl_SHA2 pipeline except that sphlib's sha2 implementation supports
partial bytes, which I will not exercise in qpdf or our tests.
