2017-06-16Plug leak of uri if creating link fails.Sebastian Rasmussen
2017-04-27Include required system headers.Tor Andersson
2017-04-13Fix 697725: silly typo when parsing GoToR destination.Tor Andersson
2017-04-11Bug 697662: Support named actions to first/last/next/previous page.Sebastian Rasmussen
2017-03-28Rejig fz_new_annot to fz_new_derived_annot.Robin Watts
More consistent with the rest of the code.
2016-11-21Harden viewers against failures when loading outlines.Tor Andersson
Ignore invalid page references in outlines. This was shown by a file that had [null 0 0 1] as a link dest. Attempting to parse that threw an error, which caused the whole outline load to fail.
2016-11-16pdf: Use '#page=N' for remote destination pages.Tor Andersson
As per Adobe's recommendation: https://helpx.adobe.com/acrobat/kb/link-html-pdf-page-acrobat.html
2016-11-14pdf: Use URI dictionary for relative URIs.Tor Andersson
2016-11-14Add/fix page coordinates to link targets.Tor Andersson
Correctly transformed target coordinates for PDF. Target coordinates for EPUB and HTML.
2016-10-28Clean up link destination handling.Tor Andersson
All link destinations should be URIs, and a document specific function can be called to resolve them to actual page numbers. Outlines have cached page numbers as well as string URIs.
2016-10-18Avoid checking argument to fz_drop_*()/fz_free().Sebastian Rasmussen
As fz_drop_*()/fz_free() all must handle NULL.
2016-10-16Avoid casting when dropping super objects.Sebastian Rasmussen
2016-10-07pdf: Remove unneccessary document argument to pdf_to_utf8 etc.Tor Andersson
2016-10-07Add annotation editing functions and clean interface of existing ones.Tor Andersson
2016-10-07Remove separate tmp/deleted/changed annotation lists.Tor Andersson
Use a flag in the pdf_annot struct instead. Don't pass pdf_document to annotation edit functions.
2016-09-23Clean up annotation enum names.Tor Andersson
Put them in the PDF name space and separate words with underscores. Remove redundant namespace prefixes in java constants. Device.FLAG_MASK rather than Device.FZ_DEVFLAG_MASK. Use namespace for PDF annotation flag enum.
2016-07-08Separate close and drop functionality for devices and writers.Tor Andersson
Closing a device or writer may throw exceptions, but much of the foreign language bindings (JNI and JS) depend on drop to never throw an exception (exceptions in finalizers are bad).

2016-07-08Slim pdf_annot struct: remove cached pagerect field.Tor Andersson
2016-07-06Start slimming pdf_page.Tor Andersson
We want to turn pdf_page into a thin wrapper around a pdf_obj, so that any updates to the underlying PDF objects will be reflected without having to reload the pdf_page.
2016-07-06pdf: Drop generation number from public interfaces.Tor Andersson
The generation number is only needed for decryption, and is assumed to be zero or irrelevant for all other uses. Store the original object number and generation in the xref slot, so that we can decrypt them even when the objects have been renumbered, without needing to pass the original object number around through the stream loading APIs.
2016-04-12Fix PDF annotations not appearing after creation.Robin Watts
Caused by a mismatch in the annotation creation/loading code.

2015-03-24Rework handling of PDF names for speed and memory.Robin Watts
Currently, every PDF name is allocated in a pdf_obj structure, and comparisons are done using strcmp. Given that we can predict most of the PDF names we'll use in a given file, this seems wasteful. The pdf_obj type is opaque outside the pdf-object.c file, so we can abuse it slightly without anyone outside knowing. We collect a sorted list of names used in PDF (resources/pdf/names.txt), and we add a utility (namedump) that preprocesses this into 2 header files. The first (include/mupdf/pdf/pdf-names-table.h, included as part of include/mupdf/pdf/object.h), defines a set of "PDF_NAME_xxxx" entries. These are pdf_obj *'s that callers can use to mean "A PDF object that means literal name 'xxxx'" The second (source/pdf/pdf-name-impl.h) is a C array of names. We therefore update the code so that rather than passing "xxxx" to functions (such as pdf_dict_gets(...)) we now pass PDF_NAME_xxxx (to pdf_dict_get(...)). This is a fairly natural (if widespread) change. The pdf_dict_getp (and sibling) functions that take a path (e.g. "foo/bar/baz") are therefore supplemented with equivalents that take a list (pdf_dict_getl(... , PDF_NAME_foo, PDF_NAME_bar, PDF_NAME_baz, NULL)). The actual implementation of this relies on the fact that small pointer values are never valid values. For a given pdf_obj *p, if NULL < (intptr_t)p < PDF_NAME__LIMIT then p is a literal entry in the name table. This enables us to do fast pointer compares and to skip expensive strcmps. Also, bring "null", "true" and "false" into the same style as PDF names. Rather than using full pdf_obj structures for null/true/false, use special pointer values just above the PDF_NAME_ table. This saves memory and makes comparisons easier.
2015-02-26tweak pdf_parse_file_specRobin Watts
pdf_parse_file_spec sometimes extracts the wrong path from a FileSpec: E.g. the /DOS path should never be returned under Unix systems, neither should be the old /Mac paths. For consistency, this patch also converts filesystem paths under Windows into a format applications will expect (e.g. from "/C/path/..." to "C:\path\..."). Finally, pdf_parse_file_spec is exposed to callers (SumatraPDF requires that for manually processing FZ_ANNOT_FILEATTACHMENT and embedded files).
2015-02-17Add ctx parameter and remove embedded contexts for API regularity.Tor Andersson
Purge several embedded contexts: Remove embedded context in fz_output. Remove embedded context in fz_stream. Remove embedded context in fz_device. Remove fz_rebind_stream (since it is no longer necessary). Remove embedded context in svg_device. Remove embedded context in XML parser. Add ctx argument to fz_document functions. Remove embedded context in fz_document. Remove embedded context in pdf_document. Remove embedded context in pdf_obj. Make fz_page independent of fz_document in the interface. We shouldn't need to pass the document to all functions handling a page. If a page is tied to the source document, it's redundant; otherwise it's just pointless. Fix reference counting oddity in fz_new_image_from_pixmap.
2015-02-17Rename fz_close_* and fz_free_* to fz_drop_*.Tor Andersson
Rename fz_close to fz_drop_stream. Rename fz_close_archive to fz_drop_archive. Rename fz_close_output to fz_drop_output. Rename fz_free_* to fz_drop_*. Rename pdf_free_* to pdf_drop_*. Rename xps_free_* to xps_drop_*.
2014-05-19Make unresolvable link destinations warnings instead of errors.Tor Andersson
See bug 693314 (file Z23-04.pdf) for an example file.
2014-03-25Break dependency of pdf-annot.c to graphics library.Tor Andersson
2014-03-19Add routine to clean pdf content streams for pages.Robin Watts
New routine to filter the content streams for pages, xobjects, type3 charprocs, patterns etc. The filtered streams are guaranteed to be properly matched with q/Q's, and to not have changed the top level ctm. Additionally we remove (some) repeated settings of colors etc. This filtering can be extended to be smarter later. The idea of this is to both repair after editing, and to leave the streams in a form that can be easily appended to. This is preparatory to work on Bates numbering and Watermarking. Currently the streams produced are uncompressed.
2014-02-25Support text (aka sticky note) annotationsPaul Gardiner
2014-02-14Add function for creating form fields (widgets)Paul Gardiner
This feature is being implemented mostly for the purpose of permitting the addition to a page of invisible signatures. Also change pdf_create_annot to make freshly created annotations printable by default.
2013-11-14Fix slip with use of tail pointer for the annotations listPaul Gardiner
pdf_load_annots was leaving the tail pointer pointing at the automatic variable head in the case of the page having no annotations.
2013-11-08Use an end pointer for the annotation list to avoid unnecessary iterationPaul Gardiner
2013-11-06Place newly created annotations at the end of the annotation listPaul Gardiner
This fixes bug 694755. Thank you to Michael Cadihac for the patch
2013-11-05Fix bug 694730: Wrong bbox in one-point ink annotationPaul Gardiner
Zero and one-point case both lead to an empty rectangle, but the one-point case needs expanding but wasn't because fz_expand_rect treats an empty rectangle as a special case (as it should)
2013-09-27tweak pdf_parse_actionSimon Bünzli
* Destination names are a name and not a string * Expose whether a /Launch action points to a path or a URI
