Patch from Rahul Bhalerao * modules/indic/indic-ot-class-tables.c: Change the class of U+0C31 from '_ct' to '_bb'. 2006-10-12 Behdad Esfahbod Bug 358174 – Reph and Vattu forms of Assamese character RA(U+09F0) are not rendered. Patch from Rahul Bhalerao * modules/indic/indic-ot-class-tables.c: Change the class bit of U+09F0 from '_ct' to '_rv'. 2006-10-07 Behdad Esfahbod * examples/Makefile.am: * examples/test-latin.txt: Add part of Jabberwocky as Latin test text. 2006-10-02 Behdad Esfahbod Bug 356685 – [or_IN] Rendering of consonant+0x0B4D+0x0B2F is wrong Patch from Rahul Bhalerao * modules/indic/indic-ot-class-tables.c: Change _ct to _bb for various Orya characters. 2006-10-02 Behdad Esfahbod Bug 357790 – Rendering problem for malayalam consonant RA (U+0D30) Patch from Rahul Bhalerao * modules/indic/indic-ot-class-tables.c: * modules/indic/indic-ot.c (indic_ot_reorder): Fix. 2006-10-02 Behdad Esfahbod Bug 359043 – PangoRenderer does not show in API docs * docs/pango-docs.sgml: Hook PangoRenderer docs. 2006-10-02 Behdad Esfahbod Bug 359046 – renderdemo.c unconditionally use GLib 2.12 * configure.in: Require glib 2.12, for Unicode 5.0 data files. 2006-09-25 Behdad Esfahbod Bug 357686 – pangocairo-font.c: illegal g_object_unref in pango_cairo_font_get_hex_box_info * pango/pangocairo-font.c (_pango_cairo_font_get_hex_box_info): Remove wrong g_object_unref (fontmap). 2006-09-22 Behdad Esfahbod Bug 357228 – Remove aix specific hack from configure.in * configure.in: Remove hack added back 2002 that is not required anymore. 2006-09-18 Behdad Esfahbod * configure.in: Step module interface version to 1.6.0 because of the script_break() slight change of behavior and anticipated changes to the module interface this cycle. 2006-09-18 Behdad Esfahbod Part of Bug 350132 – backspacing doesn't work properly for Arabic * configure.in: * modules/arabic/Makefile.am: * modules/arabic/arabic-lang.c: Add a simple Arabic language engine. Currently it just makes sure that backspace_deletes_character is not set on ALEF-MADDA combinations. 2006-09-18 Behdad Esfahbod * tools/gen-script-table.pl: * pango/pango-script-table.h: * pango/pango-script.c (pango_script_for_unichar): Minor simplification. * tests/testscript.c (test_script_lookup): Update to pass. 2006-09-18 Behdad Esfahbod * pango/pangoft2-render.c (pango_ft2_font_render_glyph): Remove a couple of unnecessary static variables. 2006-09-18 Behdad Esfahbod Bug 356194 – more pango_get_log_attrs problems * pango/break.c (tailor_break): New function. Simply calls the script_break() function of the language engine, if any. * pango/break.c (pango_break): Call pango_default_break() unconditionally. Call tailor_break() on top of the result to tailor it using the language engines, if any. * pango/break.c (tailor_segment): Call tailor_break() on the segment, and make sure the log_attrs for the first position are not corrupted. * pango/break.c (pango_get_log_attrs): Call pango_default_break() on the entire paragraph, and call tailor_segment on each segment. * pango/pango-engine.h: Update docs about *script_break()'s behavior. 2006-09-15 Behdad Esfahbod Bug 355820 – pango_get_log_attrs broken * pango/break.c (break_it), (pango_get_log_attrs): Use PangoScriptIter to itemize text, instead of pango_script_for_unichar(). 2006-09-15 Behdad Esfahbod * pango/pangofc-fontmap.c (pango_fc_face_describe): Unset gravity on the resulting font description. We want gravity to be set on all fonts described, but not font faces. 2006-09-14 Behdad Esfahbod * modules/indic/indic-ot-class-tables.c: Change enums to macros, to get in synch with ICU shaper. No functional changes. 2006-09-14 Behdad Esfahbod * modules/indic/indic-ot.h: Change some enums to macros, to get in synch with ICU shaper. No functional changes. 2006-09-13 Behdad Esfahbod Bug 351223 – the conjuction of Con + 0x0d4d +0x0d31 of Malayalam is wrong Patch from LingNing Zhang * modules/indic/indic-ot.c (swapChars), (indic_ot_reorder): Special case the above case. 2006-09-13 Behdad Esfahbod Bug 355750 – The glyphs of the conjuctions about Cons+0x0d4d+0x0d32 of Malayalm are wrong. Patch from LingNing Zhang * modules/indic/indic-ot-class-tables.c (mlymCharClasses): Change U+0D32 from _bb to _ct. 2006-09-13 Behdad Esfahbod Bug 349876 – U+0x0904 of Devanagari need be "independent vowel", but it is "reserved" in Pango Patch from LingNing Zhang * modules/indic/indic-ot-class-tables.c (devaCharClasses): Change U+0904 from _xx to _iv. 2006-09-13 Behdad Esfahbod Bug 355550 – Miscalculation of logical attributes in pango_get_log_attrs() Patch from Theppitak Karoonboonyanan * pango/break.c (pango_get_log_attrs): Pass the correct lang_engine to pango_break(). 2006-09-13 Behdad Esfahbod * pango/modules.c (pango_engine_pair_get_engine): Err about failing to load engine only once per module. 2006-09-13 Behdad Esfahbod Bug 355697 – The IndicOTClassTable of Oriya has a error. * modules/indic/indic-ot-class-tables.c: Compute lastChar from charClasses table size to avoid out-of-synch. 2006-09-13 Behdad Esfahbod Part of Bug 355782 – Misaligned extents in pango * pango/pango-layout.c (pango_layout_get_extents_internal), (pango_layout_get_extents), (pango_layout_iter_copy), (pango_layout_get_iter), (pango_layout_iter_get_line_extents): Add a new internal member layout_width to PangoLayoutIter. Set it up in pango_layout_get_extents_internal and use in pango_layout_iter_get_line_extents to fix misalignment of ink link extents. 2006-09-13 Behdad Esfahbod "Thou shalt not touch code that does not fit in thy brain." * pango/pango-layout.c (update_cluster): Add cluster_start_index parameter back in. 2006-09-13 Behdad Esfahbod * pango/pango-engine.h: Remove unnecessary 'static' in type definition that causes a relocation. * pango/shape.c (pango_shape): Make sure last_cluster is invalid. 2006-09-13 Behdad Esfahbod Part of Bug 355782 – Misaligned extents in pango * pango/pango-layout.c (cluster_width): Rewrite based on is_cluster_start instead of accessing log_clusters directly. This is more robust as next_cluster uses that, so the two match now. * pango/pango-layout.c (update_cluster): Remove the cluster_start_index parameter and use iter->cluster_start instead. * pango/pango-layout.c (pango_layout_iter_copy): Fix typo in copying iter->cluster_width. * pango/pango-layout.c (pango_layout_iter_get_cluster_extents): Add an assert to make sure iter->cluster_width is correctly set. * pango/pango-layout.c (pango_layout_iter_get_char_extents): Remove assert that was readded above to check more cases. 2006-09-12 Behdad Esfahbod Bug 355605 – hexbox with 0000 in it * modules/hangul/hangul-fc.c (render_syllable): If decomposition fails, backup and add a single hexbox glyph for the original character. 2006-09-11 Behdad Esfahbod Bug 355435 – Invalid calls to pango_map_get_engine() Patch from Theppitak Karoonboonyanan * pango/break.c (pango_get_log_attrs): * pango/pango-renderer.c (add_underline): * pango/pangofc-font.c (pango_fc_font_find_shaper): * pango/pangowin32.c (pango_win32_font_find_shaper): * pango/pangox.c (pango_x_font_find_shaper): Pass a PangoScript to pango_map_get_engine, not a gunichar! 2006-09-11 Behdad Esfahbod Bug 347146 – underline/overstrike spaces * pango/pango-renderer.c (add_underline), (add_strikethrough), (pango_renderer_draw_layout_line): Use logical extents for x and width of underline/strikethrough, such that trailing spaces are correctly handled. * pango/pango-layout.c (pango_layout_run_get_extents): Use logical rect for underline/strikethrough, and reflect that in run ink extents. * pango/pango-layout.c (pango_layout_line_get_extents): Don't let runs with empty ink extents affect total ink extents. 2006-09-10 Behdad Esfahbod Bug 352535 – Ink extents of empty glyph * pango/pangocairo-fcfont.c (pango_cairo_fc_font_get_glyph_extents): Return zero ink_rect for PANGO_GLYPH_EMPTY. 2006-09-08 Behdad Esfahbod * examples/cairotwisted.c: A simple text-on-path example using pangocairo. * examples/Makefile.am: Update. 2006-09-08 Behdad Esfahbod * pango/fonts.c (find_field_any): Parse style. It was dropped when I was adding support for gravity. 2006-08-31 Behdad Esfahbod * pango/pango-layout.c, pango/pangox-fontmap.c, pango/pangox.c: Minor doc syntax update. 2006-08-30 Behdad Esfahbod Bug 148732 – cursor movenmet is not correct in gedit when I type Arabic text. * pango/pango-layout.c (pango_layout_move_cursor_visually): Update locally cached line properties upon line change. 2006-08-30 Behdad Esfahbod * modules/Makefile.am (pango.modules): Improve the conditional to ignore included modules. 2006-08-30 Behdad Esfahbod Bug 352811 – SIGSEGV with pango(cairo)-view on HP-UX * modules/Makefile.am (pango.modules): Don't hardcode .so extension. Look for .la instead. 2006-08-30 Behdad Esfahbod Bug 353525 – libpangoft2-1.0.so.0: undefined reference to `pango_font_description_get_gravity' * examples/Makefile.am: Explicitly link to the just built pangoft2 for pangocairo uses, like we already do for pangoxft. 2006-08-28 Tor Lillqvist * modules/basic/Makefile.am: Have basic-win32.c instead of basic-win32.lo depend on usp10.h so things work out also in case the basic-win32 module is compiled in. 2006-08-26 Behdad Esfahbod Bug 349813 – typo in docs for pango_layout_move_cursor_visually * pango/pango-layout.c (pango_layout_move_cursor_visually): Fix typo. 2006-08-23 Tor Lillqvist * pango/Makefile.am * examples/Makefile.am * pango/testfonts.c * examples/pangowin32tobmp.c: Rename pango/testfonts.c to examples/pangowin32tobmp.c. (#104151) 2006-08-22 Behdad Esfahbod * pango/pango-context.c (itemize_state_process_run): Replace (!isgraph && !isspace) with (!isprint) which is equivalent. Also, update comments. 2006-08-22 Behdad Esfahbod Part of Bug 145275 – Font selection for space characters * pango/pango-context.c (itemize_state_process_run): Find shaper/font for Private Use and space characters too. Finding shaper for Private Use is needed for any practical use of those areas. Ideally, spaces should be synthesized if they are not available in the font, but falling back to other fonts is far easier, and should give pretty good results with the current set of common fonts. These fixes allow Firefox+Pango to render MathML like Firefox+Xft does. 2006-08-22 Behdad Esfahbod * pango/fonts.c (gravity_map): Rename "Upright" to "Not-Rotated". Also, reorder the user-friendly names (Not-Rotated, Rotated-Left, ...) before the enum names (South, East, ...) such that they are used to describe fonts. 2006-08-21 Behdad Esfahbod Bug 352114 – pango-1.14: generated docs still contain old example code * docs/tmpl/pangocairo.sgml: Update cairo example code to that of examples/cairosimple.c. 2006-08-20 Behdad Esfahbod Support per-item gravity. * pango/pango-context.c (update_attr_iterator), (itemize_state_init), (itemize_state_update_for_new_run), (itemize_state_process_run): Make per-item gravity work, by setting gravity into font description before loading fonts. Also, allow the context font description to override the gravity (but not centered_baseline.) * pango/pangocairo-fcfont.c (_pango_cairo_fc_font_new): Get gravity from font description, not context. * pango/pangofc-fontmap.c (fontset_hash_key_equal), (fontset_hash_key_hash), (fontset_hash_key_copy), (pango_fc_make_pattern), (pango_fc_font_map_get_patterns), (pango_fc_font_map_load_fontset), (pango_fc_font_description_from_pattern): Get gravity from font description, not context. Moreover, put it into pattern, and reconstruct it out of font patterns. * pango/pangofc-private.h: Define PANGO_FC_GRAVITY, which is the key we put PangoGravity into an FcPattern under. 2006-08-20 Behdad Esfahbod * docs/pango-sections.txt: * docs/tmpl/fonts.sgml: * pango/fonts.c (pango_font_description_set_gravity), (pango_font_description_get_gravity), (pango_font_description_merge_static), (pango_font_description_better_match), (pango_font_description_equal), (pango_font_description_hash), (find_field_any), (pango_font_description_from_string), (pango_font_description_to_string): * pango/pango-font.h: * pango/pango.def: Add gravity in PangoFontDescription. 2006-08-20 Behdad Esfahbod * pango/pango-matrix.c (pango_matrix_to_gravity): Correct switched return value of EAST/WEST. * pango/pango-types.h (PangoGravity): Add PANGO_GRAVITY_AUTO. * pango/pango-context.h: Add pango_context_get_gravity(). * examples/renderdemo.c (parse_gravity), (parse_options): * pango/pango-context.c (pango_context_init), (update_resolved_gravity), (pango_context_set_matrix), (pango_context_set_base_gravity), (pango_context_get_gravity), (itemize_state_init), (get_shaper_and_font): * pango/pango-layout.c (line_set_resolved_dir): * pango/pangocairo-fcfont.c (pango_cairo_fc_font_get_metrics), (pango_cairo_fc_font_glyph_extents_cache_init), (_pango_cairo_fc_font_new): * pango/pangofc-fontmap.c (pango_fc_make_pattern), (pango_fc_font_map_load_fontset): * pango/pango.def: * docs/pango-sections.txt: * docs/tmpl/main.sgml: Update to above. 2006-08-20 Behdad Esfahbod * examples/renderdemo.c (parse_options): * examples/renderdemo.h: Change the --rotate parameter to double now that we depend on a recent-enough glib. 2006-08-20 Behdad Esfahbod Bug 351496 – PangoAnalysis::gravity breaks binary compatibility * pango/pango-item.h (PangoAnalysis): Use bitfields for level. 2006-08-17 Hans Breuer * pango/makefile.msc pango/pango.def : updated * pango/break.c(1630) : error C2059: syntax error : '}' Intializing a struct with empty braces is not supported with MSVC, instead use 0. * pango/pangocairo.def : removed pango_fc_font_(map_)get_type pangocairo has either win32 fonts or freetype. The former is more usual. * pango/pango-utils.c : replaced M_PI by G_PI (from glib/gtypes.h). 2006-08-17 Behdad Esfahbod Part of Bug 348825 – pango should optimize away calls to FcFontSort as much as possible * pango/pangofc-fontmap.c: Increase FONTSET_CACHE_SIZE from 16 to 64. 2006-08-17 Tor Lillqvist * pangowin32.pc.in: Drop @WIN32_LIBS@, no need to search -lgdi32 when linking apps that link with libcairowin32. * pango/pango.def: Add two symbols. 2006-08-16 Behdad Esfahbod Bug 351585 – API documentation issues with 2.15 release * pango/fonts.c (pango_font_describe_with_absolute_size): Add Since tag to docs. 2006-08-16 Behdad Esfahbod * pango/pango-layout.c (line_set_resolved_dir): Adjust line resolved_dir according to context base_gravity, like we do in itemize_state_add_character(). 2006-08-16 Behdad Esfahbod * examples/viewer-pangocairo.c (render_callback): Render block progression and line direction arrows, and a base gravity roof-top. * pango/pango-matrix.c (pango_matrix_to_gravity): New function. * pango/pango-utils.c (pango_gravity_to_rotation): New function. * pango/pangocairo-fcfont.c (_pango_cairo_fc_font_new): Use pango_gravity_to_rotation(). * pango/pango-utils.h: * pango/pango-types.h: Reorder a bit. * examples/Makefile.am: * examples/test-chinese.txt: New test text for Chinese. * pango/check.defs: New script that checks that all the exported symbols are listed in the respective .def file. (only checks the libraries actually built. No win32 for example.) * pango/Makefile.am: Hook check.defs as a 'make check' test. * pango/pango.def: * pango/pangoft2.def: * pango/pangocairo.def: Update. * docs/tmpl/glyphs.sgml: * docs/tmpl/main.sgml: * docs/pango-sections.txt: Update. 2006-08-16 Behdad Esfahbod * modules/basic/basic-fc.c (fallback_shape): Remove redundant positioning block! 2006-08-15 Behdad Esfahbod * pango/pango-layout.c (pango_layout_run_get_extents): * pango/glyphstring.c (pango_glyph_string_extents_range): Return if none of logical_rect or ink_rect is non-NULL. * pango/pango-item.h (PangoAnalysis): Add new member centered_baseline which if set, makes item rendered such that ascent == descent. * pango/pango-context.c (itemize_state_init), (itemize_state_add_character): * pango/pango-renderer.c (pango_renderer_draw_layout_line): Implement centered_baseline. * pango/pangocairo-fcfont.c (pango_cairo_fc_font_get_metrics): When adjusting ascent/descent for vertical fonts, adjust strikethrough and underline position too. * docs/tmpl/main.sgml: Document new struct member. 2006-08-15 Behdad Esfahbod * modules/basic/basic-fc.c (basic_engine_shape): Use analysis->gravity to detect vertical fonts, instead of poking into the font_pattern. 2006-08-15 Behdad Esfahbod * modules/basic/basic-fc.c (basic_engine_shape): Always use fallback shaping for vertical fonts. * pango/pango-context.c (get_shaper_and_font): Always use basic shaper for vertical items (east/west gravity). 2006-08-15 Behdad Esfahbod * examples/renderdemo.c (do_output): Render the header with SOUTH gravity. * pango/pangocairo-fcfont.c (pango_cairo_fc_font_get_metrics), (pango_cairo_fc_font_glyph_extents_cache_init): Center baseline for east/west gravity in pango_font_metrics too. 2006-08-15 Behdad Esfahbod * examples/HELLO.utf8: Remove excess LRM. * examples/viewer-pangocairo.c (render_callback): Draw baselines in border-drawing mode. * pango/pango-layout.c (pango_layout_line_get_extents): Make sure we set logical_rect.y on empty lines. Previously empty lines had wrong baseline. The code apparently was written like that intentionally, but I cannot find out why. 2006-08-15 Behdad Esfahbod * pango/break.c (pango_get_log_attrs): Remove initliazer members for analysis, let compiler zero them all. Fixes compile break after adding the gravity member inside there. 2006-08-15 Behdad Esfahbod * pango/pango-context.c (itemize_state_add_character): Fix handling of WEST and EAST gravity effect on bidi level. * pango/pangocairo-fcfont.c (pango_cairo_fc_font_glyph_extents_cache_init): For NORTH gravity (upside down text), swap ascent and descent, and for EAST/WEST, center baseline between ascent/descent. * pango/shape.c (pango_shape): If glyph width is negative, negate it and shift glyph by that amount. This allows having font matrices that essentially move the glyph origin to the right of the glyph to still work. 2006-08-15 Behdad Esfahbod * pango/pangocairo-fcfont.c (pango_cairo_fc_font_get_scaled_font), (_pango_cairo_fc_font_new): Move font_matrix rotation into font_new as we use only rotation and no translation anymore. 2006-08-15 Behdad Esfahbod * docs/pango-sections.txt: * docs/tmpl/main.sgml: * examples/renderdemo.c (parse_gravity), (parse_options): * pango/pango-context.c (pango_context_init), (pango_context_get_base_gravity), (itemize_state_add_character): * pango/pango-types.h: * pango/pangocairo-fcfont.c (pango_cairo_fc_font_get_scaled_font): * pango/pangofc-fontmap.c (pango_fc_make_pattern): Oops. Exchange west<->east and north<->south gravities. The gravity is the side that the glyph sits on. So, for normal Latin text for example, gravity is south, not north. 2006-08-15 Behdad Esfahbod * examples/renderdemo.c (do_output), (parse_gravity), (parse_options): Support --gravity. * pango/pangocairo-fcfont.c (pango_cairo_fc_font_get_scaled_font), (compute_glyph_extents), (_pango_cairo_fc_font_new): Load rotated scaled_fonts to handle gravity. * pango/pangofc-fontmap.c (pango_fc_make_pattern), (pango_fc_font_map_get_patterns), (pango_fc_font_map_load_fontset): Set FC_VERTICAL_LAYOUT on West and East gravity. 2006-08-15 Behdad Esfahbod * pango/pango-context.c (itemize_state_process_run): Add FIXME note about handling item gravity. * pango/pangofc-fontmap.c (fontset_hash_key_equal), (fontset_hash_key_hash), (fontset_hash_key_copy), (pango_fc_font_map_get_patterns): Add gravity into the hask key. 2006-08-15 Behdad Esfahbod * pango/pango-item.h: Add a gravity member to PangoItem, and * pango/pango-context.c (itemize_state_init), (itemize_state_add_character): Propagate context base_gravity into items. 2006-08-15 Behdad Esfahbod * pango/pango-types.h: Add enum PangoGravity. * pango/pango-context.h: * pango/pango-context.c (pango_context_set_base_gravity), (pango_context_get_base_gravity): New functions. * pango/pango.def: * docs/pango-sections.txt: Hook new API.
