2012-12-31SHA2 pipeline with support for 256, 384, and 512 bitsJay Berkenbilt
Implemented pipeline around sph sha calls using standard test vectors for full-byte values. Did not test or support partial byte values.
2012-12-31Incorporate sha2 code from sphlib 3.0Jay Berkenbilt
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.

2012-11-20Ignore objects with offset 0Jay Berkenbilt
2012-09-23Allow reading from InputSource and writing to PipelineJay Berkenbilt
Allowing users to subclass InputSource and Pipeline to read and write from/to arbitrary sources provides the maximum flexibility for users who want to read and write from other than files or memory.

2012-09-06Add QPDFWriter::setExtraHeaderTextJay Berkenbilt
2012-09-06Reset state in QPDF::calculateLinearizationDataJay Berkenbilt
This makes it possible to use two different writers to write linearized files from the same QPDF object.
2012-09-06Fix segmentation fault with use of QPDFWriter::setOutputMemoryJay Berkenbilt
2012-08-11Prepare 3.0.1 releaserelease-qpdf-3.0.1Jay Berkenbilt
2012-08-11Bug fix: let EOF resolve literal tokenJay Berkenbilt
Previously only whitespace and comments did it. This fix is needed for object streams whose last object is a literal (name, integer, real, string) not terminated by space or newline.
2012-08-11Refactor: move resolution of literal to its own methodJay Berkenbilt

2012-07-22Windows compilation fixesJay Berkenbilt
2012-07-21Implement QPDFObjectHandle::parseJay Berkenbilt
Move object parsing code from QPDF to QPDFObjectHandle and parameterize the parts of it that are specific to a QPDF object. Provide a version that can't handle indirect objects and that can be called on an arbitrary string. A side effect of this change is that the offset used when reporting invalid stream length has changed, but since the new value seems like a better value than the old one, the test suite has been updated rather than making the code backward compatible. This only effects the offset reported for invalid streams that lack /Length or have an invalid /Length key. Updated some test code and exmaples to use QPDFObjectHandle::parse. Supporting changes include adding a BufferInputSource constructor that takes a string.
2012-07-21Move readToken from QPDF to QPDFTokenizerJay Berkenbilt
2012-07-21Refactor: pull *InputSource out of QPDFJay Berkenbilt
InputSource, FileInputSource, and BufferInputSource are now top-level classes instead of privately nested inside QPDF.
2012-07-18Prevent seeking before beginning of BufferInputSourceJay Berkenbilt
2012-07-16Add command line option to copy encryption from other fileJay Berkenbilt
Add --copy-encryption and --encryption-file-password options to qpdf. Also strengthen test suite for copying encryption. The strengthened test suite would have caught the failure to preserve AES and the failure to update the file version, which was invalidating the encrypted data.
2012-07-16Minor fixes to copyEncryptionParametersJay Berkenbilt
This fixes were to code added yesterday; the problems would not have impacted any previously released code. These are all changes related to the possibility that copyEncryptionParameters may be called on behalf a different QPDF than the one being written.
2012-07-16Bug fix: preserve AES when copying encryption parametersJay Berkenbilt
2012-07-15qpdf: push inherited attributes to page when showing imagesJay Berkenbilt
from qpdf command-line tool
2012-07-14Add public QPDFWriter::copyEncryptionParametersJay Berkenbilt
Method to copy encryption parameters from another file. Adapted from existing code to copy encryption parameters from the original file.
2012-07-14Have QPDFWriter detect foreign objects while writingJay Berkenbilt
Throw an exception that directs the user to QPDF::copyForeignObject.
2012-07-11Support copying objects from another QPDF objectJay Berkenbilt
This includes QPDF::copyForeignObject and supporting foreign objects as arguments to addPage*.
2012-07-11Add concept of reserved objectsJay Berkenbilt
QPDFObjectHandle::{new,is,assert}Reserved, QPDF::replaceReserved provide a mechanism to add objects to a PDF file when there are circular references. This is a prerequisite to copying objects from one PDF to another.
2012-07-08Fix: make unparse virtual for Null and RealJay Berkenbilt
2012-07-08Added assertNumber and assertScalar to QPDFObjectHandleTobias Hoffmann
2012-07-08Added public assert{Type} methods to QPDFObjectHandleTobias Hoffmann
2012-07-07Build this->all_pages while traversing with pushInheritedAttributesToPageTobias Hoffmann
2012-07-07Don't require stream data provider to know length in advanceJay Berkenbilt
Breaking API change: length parameter has disappeared from the StreamDataProvider version of QPDFObjectHandle::replaceStreamData since it is no longer necessary to compute it in advance. This breaking change is justified by the fact that removing the length parameter provides the caller an opportunity to simplify the calling code.
2012-07-06Add QPDFWriter method to output to FILE*Jay Berkenbilt
2012-07-05Limited inheritance to the attributes explicitly listed in the PDF specTobias Hoffmann
Previous versions of qpdf incorrectly passed arbitrary objects from /Pages objects down to individual pages in direct contradition with the PDF specification. These are now left in /Pages. When intermediate /Pages nodes are being discarded as when the /Pages tree is being flattened, a warning is issued when unknown keys are encountered.
2012-07-04Added public method QPDF::pushInheritedAttributesToPageTobias Hoffmann
Refactored optimizePagesTree to pushInheritedAttributesToPage and made public
2012-06-27Add a few minor enhancements to recent workJay Berkenbilt
Test coverage case for new newStream method Expose decimal_places argument for double-based newReal All enhancements suggested by Tobias.
2012-06-27Add Pl_Concatenate filterTobias Hoffmann
2012-06-27Add QPDFObjectHandle::newStream(QPDF *, std::string const&)Tobias Hoffmann
This makes the code simpler than having to create a buffer of a fixed size and copy the string to it.
2012-06-27Add QPDFObjectHandle::newReal(double)Tobias Hoffmann
