2016-02-10Refactor node shaping code.Robin Watts
We walk the text in a node to shape it in 2 different places in the code. Reformulate the code so that the 'walking' logic is commoned up.

2016-02-04Make HTML layout use harfbuzz for shaping.Robin Watts
fz_fonts gain a 'shaper' field that will be filled in as required. Use a void * rather than an hb_font_t to avoid polluting top level include space. Harfbuff handles mirroring for us, so lose the 'mirror' fields. This simplifies our wrappers around the 'standard' bidi code in that we don't need to split fragments upon mirroring. We do need to split our fragments at script changes though as harfbuzz only operates on a single font at a time. Update the html flow structure so that each flow node contains details of the the direction specified for it in the markup, the language specified for it in the markup and the script detected by the bidi code. Get the bidi code to pass out the script for each fragment as part of the callback and populate that field in the node. Ensure that we pass in the markup direction to the bidi splitting code as the 'base' direction. When feeding the bidi code, rather than feeding it paragraphs at a time, break those paragraphs if different parts of them have different marked up directions.
2016-01-28Add fallback font cache to font context.Tor Andersson
2016-01-22epub: Implement @font-face rules.Tor Andersson
Note: font->fallback is not reference counted here. The fallback mechanism is probably going to have to change when we add text shaping.
2016-01-22epub: Fix memory leak of bidi detection scratch buffer.Tor Andersson
2016-01-21epub: Put font fallback chain in fz_font.Tor Andersson
fz_encode_character_with_fallback finds the first font in the fallback chain that has the glyph encoded, and if none do then try to encode a bullet character.
2016-01-20epub: Adjust text-align based on paragraph directionality.Tor Andersson
In RTL context, text-align: left should be right, and vice versa. Since we currently ignore the dir="xxx" HTML attributes and CSS properties, always pick up the directionality from the text as if dir="auto".
2016-01-20Various formatting cleanups.Tor Andersson
2016-01-20Tidy bidirectional source.Robin Watts
Make the import follow mupdf style (better, if not perfect). Use ucdn where possible to avoid duplicating tables. Shrink the types, make them explicit (e.g. use fz_bidi_level rather than int) and make tables const. Use 32-bit integers for text.
2016-01-18Add support for bidirectional mirror charactersRobin Watts
2016-01-18Save some space in fz_html_flow with a union.Robin Watts
2016-01-18Implement R2L characterwise plotting in the html layout.Robin Watts
2016-01-18Ensure layout honours text directional (block level).Robin Watts
2016-01-18Process HTML text for directionality.Robin Watts
After we parse html text from an ebook run it through the unicode bidirectional algorithm to determine the directionality of each fragment. This may require splitting of fragments. Currently we don't do anything with this information.
2016-01-18Move fz_html_flow to use a bitfield.Robin Watts
Saves a bit of memory, and prepares for the addition of later fields (such as direction).

2015-10-02epub: Use CJK line breaking rules.Tor Andersson
A far cry from the full Unicode Line Breaking Algorithm, but it solves the main issues with CJK line breaking.

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: 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.

2015-04-28epub: 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

2015-04-16Fix typo in html-layout.cRobin Watts
The find_accumulated_margins function should be a void return type.
