2015-07-20Bug 696100: Fix NULL deref.Robin Watts
Check flow is not NULL before dereferencing it. Everything else in this area of the code copes with it being NULL.
2015-05-26epub: Skip initial whitespace flow nodes when finding list anchors.Tor Andersson
They are skipped during layout, so should also be skipped here. Fixes bug 695943.
2015-05-19epub: Parse CSS combinators left-associatively.Tor Andersson
Fixes bug 695994 where multiple child selectors would not match properly. The "a > b > c" rule should be interpreted as ((a > b) > c) in order to match properly.
2015-05-19epub: User stylesheets.Tor Andersson
Add -U option to mupdf and mudraw to set a user stylesheet. Uses a context to store user the stylesheet, just like the AA level.
2015-05-19epub: Use per chapter page margins.Tor Andersson
2015-05-19epub: Support !important property declarations.Tor Andersson
2015-05-18epub: Improve default stylesheet.Tor Andersson
2015-05-15epub: Use flag bits for white-space enum.Tor Andersson
2015-05-15epub: Don't inherit font-size textually, despite what the spec says.Tor Andersson
Ignore inheritance on font-size properties altogether. Since we already inherit the font-size during the 'em' calculations when laying out text, inheriting the font-size property textually will result in doubling the effect of any scaling.
2015-05-15epub: Apply @page selector margins.Tor Andersson
2015-05-15epub: Parse (and ignore) @page selector.Tor Andersson

Deal with it.
2015-05-06WIP: Add debug printing function for generated boxes.Tor Andersson
2015-05-06epub: Add 'auto' as a special number value.Tor Andersson
2015-05-06epub: Rejig CSS parser -- whitespace is significant!Tor Andersson
The selectors ".foo.bar" and ".foo .bar" are not equivalent! They should parse as "*.foo.bar" and "*.foo *.bar" but we parsed both as "*.foo.bar" due to us ignoring significant whitespace.
2015-05-05epub: Ignore missing stylesheet files.Tor Andersson
2015-05-05epub: Bail if rights.xml or encryption.xml are present (not DRM-free EPUB).Tor Andersson

2015-04-28epub: Only apply border widths when the border is visible.Tor Andersson
The border_style field was changed from an enum to an array of enums, but one place where it was used was not updated.
2015-04-27epub: Ugly hack so that table rows end up on their own lines at least.Tor Andersson
We don't support tables yet, so this is a stop gap measure.
2015-04-27epub: Support individual T,B,L,R border styles and colors.Tor Andersson
2015-04-27epub: Fix (incorrectly) recursively multiplied relative font sizes.Tor Andersson
2015-04-23epub: Support roman and alphabetic numbering in ordered lists.Tor Andersson
2015-04-20epub: list items with bullets and countersTor Andersson
2015-04-20epub: Also accept ".htm" file extension.Tor Andersson
2015-04-16Fix typo in html-layout.cRobin Watts
The find_accumulated_margins function should be a void return type.
2015-04-15epub: Take margins into account when scaling images to fit the page.Tor Andersson
2015-04-15epub: Tighten the comparison for when an image is on the current page.Tor Andersson
This solves the issue with slivers of images appearing in the margin at the bottom of the previous page.
2015-04-15epub: Be resilient in the face of broken CSS.Tor Andersson
Try to recover from syntax errors in CSS rules by skipping to the end of the declaration block. Don't abort HTML parsing on CSS errors.
2015-04-15epub: Check version number and warn if it's not an EPUB 2.0 file.Tor Andersson
2015-04-14epub: Ignore CSS3 ::before pseudo-element syntax.Tor Andersson

Fix bug 695922.
2015-04-08Fix windows builds of epub-doc.cRobin Watts
Variables need to be defined at the top of blocks.
2015-04-07Add some basic page margins to EPUB layout.Tor Andersson
Add margins of 1 em at the top and bottom of every page at the top level. TODO: This should be set from the CSS using the @page selector, and be collapsed with the body margins at the start and end of each chapter, as well as the left and right body margins.
2015-04-07Trigger default layout in fz_document layer.Tor Andersson
Trigger the default layout when needed, but only if no manual layout has been done. This avoids doing a pointless double layout (once with default when loading the document, then with the manual layout call with the desired layout options).
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.
