Tom Hacohen f0e18f58ff Evas font-engine: Cache fi when using Harfbuzz.
Soon I will also do it for all cases, but it's not possible at the
moment because we depend on harfbuzz for querying unicode properties.

Tom Hacohen 902d94afb9 Evas textblock: Added a temp fix for repch until implemented nicely.
This fix is just until we finally split to scripts and cache fi all
the time, i.e in all the possible paths (regular, fribidi and harfbuzz).

Tom Hacohen 1dac813ace Evas font-engine: Fix the fallback fribidi shaper.
Just keep the shaped string in the string object if fribidi is used
without harfbuzz.

Tom Hacohen ad3b167e88 Evas font-engine: Added support for runtime-italic/bold.
Now when setting :style=Oblique/Italic/Cursiva/Bold and etc and there's
no matching font found in the system, adjustments will be done on
runtime to support that feature.

Patch by Myoungwoon Roy Kim (roy_kim).

Tom Hacohen 6c29ea29fb Evas font-engine: Fix font size updating.
This commit fixes two types of misupdate of the font size.
1. Not updating all the fonts when not using Harfbuzz.
2. In rare cases update the wrong font when using Harfbuzz.

Tom Hacohen 0f77f14ccc Evas font-engine: Fixed walking to use ptrs instead of indexes.
I.e walk using a ptr instead of arr[i] all the time. This should make
things faster. Also as part of the change, fixed char_index to be
an offset inside the string object, and not a general offset which was
bad.

Tom Hacohen 211400d1f6 Evas font: Fixed word_prerender now that we cache everything. Do we really need it now?.
SVN revision: 56630
2011-02-01 12:18:01 +00:00
Tom Hacohen 94b5a536f0 Evas font/textblock/text: Started using string objects instead of
strings in most of the font engine (everywhere except draw).
Haven't removed the paramteres yet, but did mark them as UNUSED.
Removing them will be part of a future change.
Removed run-time OT toggling support, OT is now fast, no need for that.
Renamed all of the intl_props->text_props (because it really changed purpose now)
Fixed spliting/merging of text_props to be fast and good, not hacky and
complex like before.
Note to reviewers: Most of the changes are indentation related, sorry
for the mess, but I had to do it all in one commit, splitting was not
trivial (at least not in retrospect). The important parts are
evas_font_default_walk.x and text_utils.c. query and draw were just
adjusted a bit and the rest were only adjusted to conform to renaming or
were renaming on their own.

Tom Hacohen e809000965 Evas font-engine: Exposed PEN_Y in the walker functions and started using it instead of the hackish _pen_y.
SVN revision: 56516
2011-01-30 10:43:03 +00:00
Tom Hacohen f7dfb4d8fb Evas font-engine: pen_x is now calculated with fractional pixels (inside each item, not the case with cross-items which still use integral pixels).

Tom Hacohen ff18fa8399 Evas: Multiple changes that all relate to the Harfbuzz integration:
1. Started feeding Evas_Text_Props to the font engine instead of Evas_BiDi_Props because no we have more general text properties as well - i.e, OpenType stuff.
2. Full Harfbuzz integration which gets compiled in by default (if harfbuzz is present) but only works if the environment variable EVAS_USE_OT is set to 1 (because OT is way slower than regular text rendering).
3. Cleaned the font querying/drawing functions.
4. Added font_shaped function to all of the engines, which by default calls teh harfbuzz stuff (default on linux that is).
5. Moved some source files around a bit to make more sense.

Tom Hacohen 99a7eff130 Evas bidi + font-engine + everything affected: Changed Evas_BiDi_Props to only include the direction of the text and reverse when needed. We don't need to do full processing at this stage, because we should have split to bidi runs before.

Tom Hacohen 7bf2353f96 Evas font-engine: Fixed the first miss breaks font bug and removed the work around. My tests show it work, but just to make sure, if it doesn't for you, let me know.

2010-11-11 13:07:04 +00:00
Tom Hacohen da512dde9b Evas font-engine: Don't break if there was a previous miss. This is a workaround for a bug in the font index caching mechanism that happens if you cache the index miss before all the fonts were changed. We should probably just put a "dirty" flag on font sets that loaded more fonts or something like that.

Christopher Michael 2f3b2b99e5 Fix issue when using word-cache: Make sure we have a 'last' word
before trying to free it, else we segfault.

Fix compiler warnings wrt const vs non-const of Evas_BiDi_Props.
Fix formatting and remove whitespace also.

NB: The major change here is in evas_font_word_prerender wrt freeing
the 'last' word of the cache.

Carsten Haitzler 075531cc54 aaah... so.. if we have a fribidi lock.. shall we.. hmrrrm maybe use
it? and... lets not just throw pointer onto pipelines just for the
hell of it.. as like.. hmm the object owning the pointer might be
freed before pipelien finishes.. or hell. it might change pointer
contents? :) need to nwo dup bidi intl_props. probably a better plan..
tasn looking at you... is to fix up evas bidi utils and make the intl
props a new/free thing (and sharable eh?) with reference counts to
avoid dups (just ref up most of the time - and if u change, make a new
intl prop - dont change current one) etc. etc. for now dup - this
gives a perf hit tho. at least async rendering works now.
