GTK+-2.0源码之pango-1.15.6.tar.gz

2006-03-13  Behdad Esfahbod  <[e-mail]>

	* === Released 1.12.0 ===

	* configure.in: Version 1.12.0

	* NEWS, README: Updated.

2006-03-03  Tor Lillqvist  <[e-mail]>

	* pango/pangowin32-private.h (PING): Fix compilation error with
	MSVC. (#333115)

2006-03-01  Tor Lillqvist  <[e-mail]>

	* pango/pango-context.c (update_metrics_from_items): Check the
	font pointer being NULL to avoid crashes for at least one class of
	"bad" fonts (those without a Unicode cmap) on Win32. It would
	probably be better to prune out such fonts already in the
	enumeration phase. That would require opening (CreateFontIndirect)
	every font, though, to be able to check with GetFontData() whether
	there is a Unicode cmap. Don't know how much that would slow down
	the enumeration.

2006-02-28  Tor Lillqvist  <[e-mail]>

	* pango/pangowin32-private.h (PING)
	* pango/pangowin32.c
	* modules/basic/basic-win32.c: Use g_print() instead of printf()
	for debugging output, to enable easy redirection using GLib
	facilities. (#332855)

2006-02-26  Behdad Esfahbod  <[e-mail]>

	* === Released 1.11.99 "Just In Case" ===

	* configure.in: Version 1.11.99

	* NEWS: Updated.

2006-02-26  Behdad Esfahbod  <[e-mail]>

	* pango/pango-layout.c (pango_layout_set_text): Replace each byte in
	invalid UTF-8 sequences with '?'.  (bug #331995)

	* examples/renderdemo.c: Don't exit on invalid UTF-8 input.

2006-02-25  Hans Breuer  <[e-mail]>

	* pango/pangocairo-win32font.c(pango_cairo_win32_font_install):
	return TRUE to glyphs rendered at all (instead of box). This may
	be compiler specific (what to return w/o return) but fixes bug #332538
	
	* pango/makefile.msc: updated
	* pango/pango.def: just some sorting

2006-02-25  Behdad Esfahbod  <[e-mail]>

	Fix #135098 and #322510.

	* pango/pangowin32-fontmap.c (case_insensitive_hash)
	(case_insensitive_equal): New helper functions for string hashing
	based on ASCII case insensitivity..
	(logfont_nosize_hash): Use case_insensitive_hash().
	(logfont_nosize_equal): Use case_insensitive_equal().
	(pango_win32_font_map_init): Use the case-insensitive functions
	for the PangoWin32FontMap::families hash table.
	(pango_win32_font_map_load_font): Consequently we don't need to
	lowercase the name before looking up from the hash table.
	(get_family_name): Constify parameter.
	(get_family_name_lowercase): Not needed any longer.
	(pango_win32_font_description_from_logfont): New public
	function. Code moved from pango_win32_insert_font(). Use family
	name as such, don't lowercase it.
	(pango_win32_insert_font): Use the above new function. Don't
	bother looking for superfluos copies of the font entry as that
	shouldn't ever happen. We have pruned out fonts that differ only
	in charset already earlier.

	* pango/pangowin32.h: Declare pango_win32_font_description_from_logfont().

	* pango/pangowin32.def

2006-02-08  Anders Carlsson  <[e-mail]>

2006-02-08  Behdad Esfahbod  <[e-mail]>

	* === Released 1.11.4 ===

	* configure.in: Version 1.11.4

	* NEWS: Updated.

2006-02-06  Behdad Esfahbod  <[e-mail]>

	As cairo 1.2 seems to be delayed infinitely, make all cairo HEAD
	API that we use conditional, to make a release.

	* configure.in: Depend on cairo 1.0.0 again.  Check for
	cairo_scaled_font_get_*() and cairo_scaled_font_text_extents()
	availability.

	* pango/pangocairo-font.c: Work around if the above functions are not
	available.

2006-02-06  Behdad Esfahbod  <[e-mail]>

	* pango/pango-utils.c (pango_matrix_copy, pango_matrix_free):  If
	NULL is passed to _copy, return NULL with no warning.  If NULL is
	passed to _free, do nothing with no warning.  Docs updated.

	* examples/viewer-pangoxft.c (render_callback): Multiply x,y by
	PANGO_SCALE, as pango_xft_render_layout takes coordinates in 
	Pango units weirdly enough.

	* viewer-pangocairo.c (render_callback): Do cairo_translate, to
	draw correct bounding boxes for x,y nonzero.

	* examples/renderdemo.c (do_output): If context has an all-zero matrix
	set, interpret it as backend does not support transformation, so
	warn on --rotate, and do not try to rotate.

	* examples/viewer-pangox.c (pangox_view_get_context): Set an all-zero
	matrix on context, to negotiate that we don't support transformations.

2006-02-06  Behdad Esfahbod  <[e-mail]>

	Bug 328067 – Install pango-view

	Added a rather generic framework for a pango-view example.  All
	backends have their own pango*-view built, and a pango-view binary
	is built too, that can choose backend via --backend.  This one is
	installed in bindir.

	* examples/Makefile.am: Updated, to build pangox-view, pangoft2-view,
	pangoxft-view, pangocairo-view, and pango-view.

	* examples/viewer.h, examples/viewer-x.c, examples/viewer-x.h
	examples/viewer-cairo.c, examples/viewer-cairo.h,
	examples/viewer-main.c, examples/viewer-pangox.c,
	examples/viewer-pangoft2.c, examples/viewer-pangoxft.c,
	examples/viewer-pangocairo.c, examples/pango-view.c,
	examples/pango-xview.c, examples/pango-ft2view.c,
	examples/pango-xftview.c, examples/pango-cairoview.c: Added.

	* examples/cairoview.c, examples/xftview.c, examples/pangoft2topgm.c,
	examples/viewer-qt.cc, examples/viewer-qt.h: Removed.

	* configure.in: Check for Cairo Xlib backend, also AC_DEFINE various
	backend bits.

2006-02-06  Behdad Esfahbod  <[e-mail]>

	* pango/pango-fontmap.c (pango_font_map_real_load_fontset): Warn
	only once per font-description that cannot be loaded.

	* pango/pangox.c: Make it not crash if no font found, like other
	backends.

2006-02-05  Behdad Esfahbod  <[e-mail]>

	* configure.in: AC_DEFINE various version components.

	* *.c: Change various const return types to G_CONST_RETURN.

2006-02-04  Behdad Esfahbod  <[e-mail]>

	Bug 324408 – tab can result in 0 characters

	* pango/pango-layout.c (shape_tab): Make sure there is
	at least an space-width of space between tab-aligned text
	and the text before it.

2006-02-04  Behdad Esfahbod  <[e-mail]>

	Bug 329528 – implement --wrap in examples/renderdemo.c
	Patch from Antoine Dopffer.

	* examples/renderdemo.c: Add --wrap option.

2006-02-04  Behdad Esfahbod  <[e-mail]>

	* pango/pango-types.h: Change PANGO_GLYPH_EMPTY to 0x0FFFFFFF, to
	not overlap with PANGO_GLYPH_UNKNOWN_FLAG (0x10000000).
	Define PANGO_GET_UNKNOWN_GLYPH(wc) that simply returns
	wc|PANGO_GLYPH_UNKNOWN_FLAG.

	* docs/pango-sections.txt, docs/tmpl/glyphs.sgml: Document new
	symbols.

	* modules/*/*.c: Use PANGO_GET_UNKNOWN_GLYPH instead of various
	backend-specific functions.

	* pango/pangofc-font.c, pango/pangoft.c, pango/pangoxft-font.c,
	* pango/pangowin32.c, pango/pangox.c: Suggest using
	PANGO_GET_UNKNOWN_GLYPH in docs.

	* pango/pangofc-font.h: Deprecate pango_fc_font_get_unknown_glyph().

	* pango/pangowin32.h: Deprecate pango_win32_get_unknown_glyph().

2006-02-04  Behdad Esfahbod  <[e-mail]>

	* pango/pangoft2.c, pango/pangoft2-render.c: Move the
	FT_IS_SFNT(font) logic into pango_ft2_get_unknown glyph.

2006-02-03  Behdad Esfahbod  <[e-mail]>

	* configure.in: AC_DEFINE the module version, such that
	pango-querymodules gets rebuilt after module version
	update.

	* pango/Makefile.am: Do not set -DMODULE_VERSION.

2006-02-03  Behdad Esfahbod  <[e-mail]>

	* configure.in: Bump pango_module_version to 1.5.0.

2006-02-03  Behdad Esfahbod  <[e-mail]>

	* Makefile.am: Distribute autogen.sh.

2006-02-02  Behdad Esfahbod  <[e-mail]>

	Finish the 'glyph 0' work of this morning:
	PANGO_GLYPH_NULL that I introduced is renamed to
	PANGO_GLYPH_EMPTY.  It means, no rendering should
	be performed.  The backends however, still return
	0 if a glyph is not found.  The modules then are
	free to replace this 0 glyph with an unknown
	character.

	* modules/arabic/arabic-fc.c, modules/basic/basic-atsui.c,
	modules/basic/basic-fc.c, modules/basic/basic-win32.c,
	modules/basic/basic-x.c, modules/hangul/hangul-fc.c,
	modules/hebrew/hebrew-fc.c, modules/indic/indic-fc.c,
	modules/khmer/khmer-fc.c, modules/syriac/syriac-fc.c,
	modules/thai/thai-fc.c, modules/tibetan/tibetan-fc.c,
	pango/pangox.c, pango/pangowin32.c:
	Adapt to above change.  Backends return 0 if glyph not
	found.

	* pango/fonts.c (pango_font_get_glyph_extents): If font
	is not usable (!PANGO_IS_FONT (font)), return the generic
	UNKNOWN_GLYPH metrics.  This is used when your backends
	are misconfigured and you don't find *any* font at all.

	* pango/pango-engince.c: Add unknown glyphs in fallback
	shaper, instead of empty glyphs.

	* pango/shape.c: Call the fall-back shaper if shaper
	fails, instead of generating a dummy glyph string ourselves.

	* pango/pango-layout.c (imposed_shape, shape_tab): Use
	PANGO_GLYPH_EMPTY instead of glyph 0.

	* pango/pango-renderer.c (pango_renderer_draw_glyph): No-op on
	PANGO_GLYPH_EMPTY instead of glyph 0.

	* pango/pangocairo-atsuifont.c, pango/pangocairo-win32font.c,
