Without 89 this fix, glyphs aren't properly aligned on a common baseline. 90 91 On 64bit systems, `FT_Pos' expands to `long int', having a width of 92 64bit. `CF2_Fixed' expands to `int' which is normally 32bit wide on 93 64bit hosts also. Wrong casts filled up the blues arrays with 94 incorrect values. Note that all blues values are accessed with the 95 `cf2_blueToFixed' macro which handles the 64bit to 32bit conversion. 96 97 * src/cff/cf2ft.h (cf2_getBlueValues, cf2_getOtherBlues, 98 cf2_getFamilyBlues, cf2_getFamilyOtherBlues): Use `FT_Pos' for 99 `data', not `CF2_Fixed'. 100 * src/cff/cf2ft.c (cf2_getBlueValues, cf2_getOtherBlues, 101 cf2_getFamilyBlues, cf2_getFamilyOtherBlues): Updated. 102 * src/cff/cf2blues.c (cf2_blues_init): Updated. 103 104 2013-05-04 Werner Lemberg <wl (a] gnu.org> 105 106 More fixes for clang's `sanitize' feature. 107 108 * src/base/ftcalc.c (FT_DivFix): Use unsigned values for 109 computations which use the left shift operator and convert to signed 110 as the last step. 111 * src/base/fttrigon.c (ft_trig_prenorm, FT_Vector_Rotate, 112 FT_Vector_Length, FT_Vector_Polarize): Ditto. 113 114 * src/cff/cffgload.c (cff_decoder_parse_charstrings): Simplify. 115 * src/cff/cffload.c (cff_subfont_load): Fix constant. 116 * src/cff/cffparse.c (cff_parse_integer, cff_parse_real, do_fixed, 117 cff_parse_fixed_dynamic): Use unsigned values for computations which 118 use the left shift operator and convert to signed as the last step. 119 120 * src/cid/cidload.c (cid_get_offset): Ditto. 121 122 * src/psaux/psconv.c (PS_Conv_ToFixed): Ditto. 123 * src/psaux/t1decode.c (t1_decoder_parse_charstrings): Ditto. 124 125 * src/truetype/ttinterp.c (TT_MulFix14, TT_DotFix14): Ditto. 126 127 2013-05-04 Werner Lemberg <wl (a] gnu.org> 128 129 Fix errors reported by clang's `sanitize' feature. 130 131 * include/freetype/internal/ftstream.h: Simplify and fix integer 132 extraction macros. 133 (FT_INT8_, FT_BYTE_I16, FT_BYTE_I32, FT_INT8_I16, FT_INT8_I32, 134 FT_INT8_I32, FT_INT8_U32): Removed. 135 (FT_PEEK_SHORT, FT_PEEK_LONG, FT_PEEK_OFF3, FT_PEEK_SHORT_LE, 136 FT_PEEK_LONG_LE, FT_PEEK_OFF3_LE): Use unsigned values for 137 computations and convert to signed as the last step. 138 139 * src/cff/cf2fixed.h (cf2_intToFixed, cf2_fixedToInt, 140 cf2_fracToFixed): Avoid shifts of negative values. 141 (cf2_intToFrac, cf2_fixedToFrac, cf2_fixedTo26Dot6): Removed, 142 unused. 143 144 * src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdEXTENDEDNMBR, 145 default>: Use unsigned values for computations and convert to signed 146 as the last step. 147 Use proper types in tracing messages. 148 149 * src/cff/cffgload.c (cff_decoder_parse_charstrings): Use unsigned 150 values for computation of operands and convert to signed as the last 151 step. 152 Use proper type in tracing message. 153 154 2013-05-03 Werner Lemberg <wl (a] gnu.org> 155 156 * src/cff/cf2blues.c: Remove dead code. 157 158 2013-05-02 Chris Liddell <chris.liddell (a] artifex.com> 159 160 * src/cff/cffgload.c: Include FT_CFF_DRIVER_H. 161 162 2013-04-27 Werner Lemberg <wl (a] gnu.org> 163 164 * docs/CHANGES: Updated. 165 * README: Improved. 166 167 2013-04-13 Werner Lemberg <wl (a] gnu.org> 168 169 [cff] Add a new Type 2 interpreter and hinter. 170 171 This work, written by Dave Arnold <darnold (a] adobe.com> and fully 172 integrated into FreeType by me, is a donation by Adobe in 173 collaboration with Google. It is vastly superior to the old CFF 174 engine, and it will replace it soon. Right now, it is still off by 175 default, and you have to explicitly select it using the new 176 `hinting-engine' property of the cff driver. 177 178 For convenience, (most of) the new files are committed separately. 179 180 * include/freetype/config/ftheader.h (FT_CFF_DRIVER_H): New macro. 181 * include/freetype/ftcffdrv.h: New file to access CFF driver 182 properties. 183 * include/freetype/fterrdef.h (FT_Err_Glyph_Too_Big): New error 184 code. 185 * include/freetype/internal/fttrace.h: Add `cf2blues', `cf2hints', 186 and `cf2interp'. 187 188 * src/cff/cffgload.h (CFF_SubFont): New member `current_subfont'. 189 * src/cff/cffobjs.h (CFF_DriverRec): New members `hinting_engine' 190 and `no_stem_darkening'. 191 * src/cff/cfftypes.h (CFF_FontRec): New member `cf2_instance'. 192 193 * src/cff/cff.c: Include new files. 194 * src/cff/cffdrivr.c (cff_property_set, cff_property_get): Handle 195 `hinting-engine' and `no-stem-darkening' properties (only the Adobe 196 engine listens to them). 197 * src/cff/cffgload.c: Include `cf2ft.h'. 198 (cff_decoder_prepare): Initialize `current_subfont'. 199 (cff_build_add_point): Handle Adobe engine which uses 16.16 200 coordinates. 201 (cff_slot_load): Handle FT_LOAD_NO_SCALE and FT_LOAD_NO_HINTING 202 separately. 203 Choose rendering engine based on `hinting_engine' property. 204 * src/cff/cffload.c (cff_font_done): Call finalizer of the Adobe 205 engine. 206 * src/cff/cffobjs.c: Include FT_CFF_DRIVER_H. 207 (cff_driver_init): Set default property values. 208 209 * src/cff/rules.mk (CFF_DRV_SRC, CFF_DRV_H): Add new files. 210 211 * src/cff/cf2*.*: New files, containing the Adobe engine. 212 213 2013-04-12 Werner Lemberg <wl (a] gnu.org> 214 215 [cff] Minor code administration issues. 216 217 * src/cff/cffgload.c (check_points): Rename to... 218 (cff_check_points): ...this and make it FT_LOCAL. 219 (cff_builder_add_point, cff_builder_add_point1, 220 cff_builder_start_point, cff_builder_close_contour, 221 cff_lookup_glyph_by_stdcharcode, cff_get_glyph_data, 222 cff_free_glyph_data): Make them FT_LOCAL. 223 224 * src/cff/cffgload.h: Updated. 225 226 2013-04-12 Werner Lemberg <wl (a] gnu.org> 227 228 Add output bitmap checksums. 229 230 Use `FT2_DEBUG=bitmap:3' for tracing. 231 232 * src/base/md5.c, src/base/md5.h: New files, taken from 233 234 http://openwall.info/wiki/people/solar/software/public-domain-source-code/md5 235 236 * include/freetype/internal/fttrace.h: Add `bitmap'. 237 238 * src/base/ftobjs.c [FT_DEBUG_LEVEL_TRACE]: Include `md5.c' 239 240 (FT_Render_Glyph_Internal) [FT_DEBUG_LEVEL_TRACE]: For tracing, 241 convert resulting bitmap to a uniform format and compute a checksum. 242 Use `bitmap' category for the tracing message. 243 244 * src/base/rules.mk (BASE_H): Updated. 245 246 * docs/LICENSE.TXT: Updated. 247 248 2013-04-12 Werner Lemberg <wl (a] gnu.org> 249 250 [cff] Add framework for CFF properties. 251 252 * include/freetype/internal/ftserv.h (FT_DEFINE_SERVICEDESCREC7): 253 New macro. 254 255 * src/cff/cffdrivr.c: Include FT_SERVICE_PROPERTIES_H. 256 (cff_property_set, cff_property_get): New functions, still empty. 257 Define `cff_service_properties' service. 258 Update `cff_services'. 259 260 * src/cff/cffpic.h: Include FT_SERVICE_PROPERTIES_H. 261 (CFF_SERVICE_PROPERTIES_GET): New macro. 262 (CffModulePIC): Add `cff_service_properties'. 263 264 2013-04-03 Werner Lemberg <wl (a] gnu.org> 265 266 [bdf] Fix Savannah bug #38589. 267 268 * src/bdf/bdflib.c (_bdf_readstream): Thinko. 269 270 2013-03-31 Werner Lemberg <wl (a] gnu.org> 271 272 * configure: Use egrep, not grep. 273 274 Problem reported Mojca Miklavec <mojca.miklavec.lists (a] gmail.com>. 275 276 2013-03-29 Werner Lemberg <wl (a] gnu.org> 277 278 * include/freetype/ftlcdfil.h: Add description of color filtering. 279 280 Based on a contribution from Antti S. Lankila <alankila (a] bel.fi> 281 (Savannah bug #38607). 282 283 2013-03-23 Werner Lemberg <wl (a] gnu.org> 284 285 [autofit] Minor. 286 287 * src/autofit/afmodule.c (af_property_set): Typo. 288 (af_autofitter_init, af_autofitter_done): Use cast. 289 290 2013-03-21 Werner Lemberg <wl (a] gnu.org> 291 292 * configure: Automatically test for `gmake' also. 293 294 Suggested by Mojca Miklavec <mojca.miklavec.lists (a] gmail.com>. 295 296 2013-03-21 Peter Breitenlohner <peb (a] mppmu.mpg.de> 297 298 Respect CONFIG_SHELL from the environment. 299 300 Some large packages using FreeType have to use a broken (deficient) 301 /bin/sh. The configure scripts (as generated by Autoconf) are 302 clever enough to find a better shell and put that one into the 303 environment variable CONFIG_SHELL. If that environment variable is 304 already set the script skips the test and assumes to be already 305 running under a good shell. 306 307 * builds/unix/detect.mk: Honour CONFIG_SHELL. 308 * builds/unix/unix-def.in (SHELL): Define. 309 310 2013-03-21 Werner Lemberg <wl (a] gnu.org> 311 312 Fix Savannah patch #7971. 313 314 * configure: Handle MAKE environment variable also. 315 316 2013-03-17 Werner Lemberg <wl (a] gnu.org> 317 318 Fix Savannah bug #38538. 319 320 * builds/amiga/src/base/ftdebug.c, builds/win32/ftdebug.c, 321 builds/wince/ftdebug.c (FT_Throw): Add function. 322 323 2013-03-17 Werner Lemberg <wl (a] gnu.org> 324 325 [raster] Remove dead code. 326 327 * src/raster/rastpic.c (ft_raster1_renderer_class_pic_init) 328 src/smooth/ftspic.c (ft_smooth_renderer_class_pic_init): Do it. 329 330 2013-03-17 Werner Lemberg <wl (a] gnu.org> 331 332 * src/pshinter/pshpic.h (GET_PIC): Use correct container. 333 334 2013-03-15 Werner Lemberg <wl (a] gnu.org> 335 336 * include/freetype/ftmoderr.h: Fix commit from 2013-03-11. 337 338 The previous version was not backward compatible. Reported by 339 Behdad. 340 341 2013-03-14 Werner Lemberg <wl (a] gnu.org> 342 343 */*: Use FT_ERR_EQ, FT_ERR_NEQ, and FT_ERR where appropriate. 344 345 FT_Err_XXX and friends are no longer directly used in the source 346 code. 347 348 2013-03-14 Werner Lemberg <wl (a] gnu.org> 349 350 New error management macros. 351 352 * include/freetype/fterrors.h (FT_ERR_XCAT, FT_ERR_CAT): Move to... 353 * include/freetype/fttypes.h: ... this file. 354 (FT_ERR, FT_ERR_EQ, FT_ERR_NEQ, FT_MODERR_EQ, FT_MODERR_NEQ): New 355 macros. 356 357 * include/freetype/freetype.h: Updated. 358 359 2013-03-14 Werner Lemberg <wl (a] gnu.org> 360 361 */*: Use FT_Err_Ok only. 362 363 This is a purely mechanical conversion. 364 365 2013-03-14 Werner Lemberg <wl (a] gnu.org> 366 367 */*: Use `FT_THROW'. 368 369 This is essentially a mechanical conversion, adding inclusion of 370 `FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for 371 stand-alone compiling modes of the rasterizer modules. 372 373 To convert the remaining occurrences of FT_Err_XXX and friends it is 374 necessary to rewrite the code. Note, however, that it doesn't harm 375 if some cases are not handled since FT_THROW is a no-op. 376 377 2013-03-13 Werner Lemberg <wl (a] gnu.org> 378 379 Introduce `FT_THROW' macro. 380 381 The idea is to replace code like 382 383 return FT_Err_Foo_Bar; 384 385 or 386 387 return CFF_Err_Foo_Bar; 388 389 with 390 391 return FT_THROW( Foo_Bar ); 392 393 The FT_THROW macro has two functions: 394 395 . It hides the module specific prefix. 396 397 .

However, as Greg Hitchcock has told us in 501 private communication, reference points get reset to zero in the MS 502 rasterizer and we follow in due course.

These tables were defined as global, mutable, visible variables, 755 and thus costing private RAM to every process that loads the 756 library (> 50 KB / process, this is huge!). 757 758 Additionally, this also made the library export the symbols 759 completely needlessly. 760 761 3. Missing `sph_' and `SPH_' prefixes to some of the definitions. 762 763 Note that this doesn't try to fix the incredibly inefficient storage 764 format for the data tables used by the code.

Consider two unit vectors (1,0) and (.6,.8) 1096 for which the true value of F_dot_P is .6 * 0x40000000 = 0x26666666. 1097 These vectors are stored as (0x4000,0) and (0x2666,0x3333) after 1098 rounding and F_dot_P is assigned 0x26660000. The lower bits were 1099 already lost while rounding the unit vector components. 1100 1101 Besides code simplification, this change can lead to better 1102 performance when FT_MulDiv with the scaled-down F_dot_P is less 1103 likely to use the costly 64-bit path. We are not changing the type 1104 of F_dot_P to FT_F2Dot14 at this point. 1105 1106 * src/truetype/ttinterp.c (Compute_Funcs): Scale F_dot_P down by 14 1107 bits and modify its use accordingly. 1108 (Direct_Move, Direct_Move_Orig, Compute_Point_Displacement): Modify 1109 the use of F_dot_P field. 1110 * src/truetype/ttobjs.c (tt_size_run_fpgm): Change arbitrary 1111 assignment of F_dot_P to its theoretical maximum in case we decide 1112 to scale back its type later. 1113 1114 2012-12-09 Johnson Y.

While still experimental, it is now 1975 mature enough to be included directly into FreeType. 1976 1977 Most of the code is based on the ClearType whitepaper written by 1978 Greg Hitchcock 1979 1980 https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx 1981 1982 which gives a detailed overview of the necessary changes to the 1983 Microsoft rasterizer so that older fonts are supported.

This glyph is a composite; 2246 the first component, `E', has an advance width of 1366 font units, 2247 while the advance width of the composite itself (which looks like 2248 uppercase `E' with dieresis) is 1367 font units. I think this is 2249 actually a bug in the font itself, because there is no reason that 2250 this glyph has not the same width as uppercase `E' without the 2251 dieresis. Anyway, it helped identify this problem. 2252 2253 Using the TrueType hinter, the correct value (1367) of `afii10023' 2254 was returned, but the autohinter mysteriously returned 1366. 2255 2256 Digging in the code showed that the autohinter recursively calls 2257 FT_Load_Glyph to load the glyph, adding the FT_LOAD_NO_SCALE load 2258 flag. However, the `linearHoriAdvance' field is still returned as a 2259 scaled value. To avoid scaling twice, the old code in autofit reset 2260 `linearHoriAdvance', using the `horiAdvance' field. This seemed to 2261 work since FT_LOAD_NO_SCALE was in use, but it failed actually, 2262 because `horiAdvance' is defined as the distance of the first 2263 subglyph's phantom points, which in turn are initialized using the 2264 advance width of the first subglyph. And as the given example 2265 shows, these widths can differ. 2266 2267 * src/autofit/afloader.c (af_loader_load_g): Temporarily set 2268 FT_LOAD_LINEAR_DESIGN while calling FT_Load_Glyph to get unscaled 2269 values for the linear advance widths. 2270 2271 2012-03-10 Werner Lemberg <wl (a] gnu.org> 2272 2273 [truetype] Fix SSW instruction. 2274 2275 * src/truetype/ttinterp.c (DO_SSW): SSW *does* use font units.

Indeed, the meanings of 3534 `miter' and `bevel' were incorrectly reversed (consistently) in 3535 both the code and comments. 3536 3537 o The way bevel joins were constructed (whether specified 3538 explicitly, or created as a result of exceeding the miter limit) 3539 did not match what is required for stroked text in PostScript or 3540 PDF. 3541 3542 The main fixes 3543 -------------- 3544 3545 o The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected. 3546 3547 o A new line join style, FT_STROKER_LINEJOIN_MITER_FIXED, has been 3548 introduced to support PostScript and PDF miter joins. 3549 3550 o FT_STROKER_LINEJOIN_MITER_VARIABLE has been introduced as an 3551 alias for FT_STROKER_LINEJOIN_MITER. 3552 3553 Additionally, a variety of stroking errors have been fixed. These 3554 would cause various artifacts (including points `at infinity'), 3555 especially when stroking poor quality fonts. 3556 3557 See 3558 3559 https://lists.gnu.org/archive/html/freetype-devel/2011-07/msg00001.html 3560 3561 for example documents. The FreeType stroker now produces results 3562 very similar to that produced by GhostScript and Distiller for these 3563 fonts. 3564 3565 Other problems 3566 -------------- 3567 3568 The following problems have been resolved: 3569 3570 o Inside corners could be generated incorrectly. Intersecting the 3571 inside corner could cause a missing triangular area and other 3572 effects. 3573 3574 The intersection point can only be used if the join is between 3575 two lines and both lines are long enough. The `optimization' 3576 condition in `ft_stroker_inside' has been corrected; this 3577 requires the line length to be passed into various functions and 3578 stored in `FT_StrokerRec'. 3579 3580 o Incorrect cubic curves could be generated. The angle 3581 calculations in `FT_Stroker_CubicTo' have been corrected to 3582 handle the case of the curve crossing the +/-PI direction. 3583 3584 o If the border radius was greater than the radius of curvature of 3585 a curve, then the negative sector would end up outside (not 3586 inside) the border. This situation is now recognized and the 3587 negative sector is circumnavigated in the opposite direction. 3588 (If round line joins are being used, this code is disabled 3589 because the line join will always cover the negative sector.) 3590 3591 o When a curve is split, the arcs may not join smoothly (especially 3592 if the curve turns sharply back on itself). Changes in 3593 direction between adjacent arcs were not handled. A round 3594 corner is now added if the deviation from one arc to the next is 3595 greater than a suitable threshold. 3596 3597 o The current direction wasn't retained if a the outline contained 3598 a zero length lineto or a curve that was determined to be 3599 `basically a point'. This could cause a spurious join to be 3600 added. 3601 3602 o Cubics with close control points could be mishandled. All eight 3603 cases are now distinguished correctly. 3604 3605 Other improvements 3606 ------------------ 3607 3608 o Borders for cubic curves could be too `flat'. 3609 FT_SMALL_CUBIC_THRESHOLD has been reduced a little to prevent 3610 this. 3611 3612 o The handling and use of movable points has been simplified a 3613 little. 3614 3615 o Various values are now computed only if the results are actually 3616 needed. 3617 3618 o The directions of the outer and inner borders have been swapped, 3619 as recommended by Graham Asher. 3620 3621 * src/base/ftstroke.c: Revised. 3622 * include/freetype/ftstroke.h: Updated. 3623 3624 2011-06-30 smail Dnmez <ismail (a] namtrac.org> 3625 3626 * builds/toplevel.mk: We use git, not CVS, thus skip `.gitignore'. 3627 3628 2011-06-29 Werner Lemberg <wl (a] gnu.org> 3629 3630 [bdf] Fix Savannah bug #33663. 3631 3632 * src/bdf/bdflib.c (_bdf_parse_glyphs): Handle negative values for 3633 ENCODING correctly. 3634 3635 * docs/CHANGES: Document it. 3636 3637 2011-06-24 Werner Lemberg <wl (a] gnu.org> 3638 3639 * Version 2.4.5 released. 3640 ========================= 3641 3642 3643 Tag sources with `VER-2-4-5'. 3644 3645 * docs/CHANGES: Updated. 3646 3647 * docs/VERSION.DLL: Update documentation and bump version number to 3648 2.4.5 3649 3650 * README, Jamfile (RefDoc), 3651 builds/win32/vc2005/freetype.vcproj, builds/win32/vc2005/index.html, 3652 builds/win32/vc2008/freetype.vcproj, builds/win32/vc2008/index.html, 3653 builds/win32/vc2010/freetype.vcxproj, builds/win32/vc2010/index.html, 3654 builds/win32/visualc/freetype.dsp, 3655 builds/win32/visualc/freetype.vcproj, 3656 builds/win32/visualc/index.html, builds/win32/visualce/freetype.dsp, 3657 builds/win32/visualce/freetype.vcproj, 3658 builds/win32/visualce/index.html, 3659 builds/wince/vc2005-ce/freetype.vcproj, 3660 builds/wince/vc2005-ce/index.html, 3661 builds/wince/vc2008-ce/freetype.vcproj, 3662 builds/wince/vc2008-ce/index.html: s/2.4.4/2.4.5/, s/244/245/. 3663 3664 * include/freetype/freetype.h (FREETYPE_PATCH): Set to 5. 3665 3666 * builds/unix/configure.raw (version_info): Set to 13:0:7. 3667 3668 2011-06-20 Werner Lemberg <wl (a] gnu.org> 3669 3670 * src/autofit/aflatin.c (af_latin_metrics_scale_dim): Fix change 3671 from 2011-05-04. 3672 3673 2011-06-19 suzuki toshiya <mpsuzuki (a] hiroshima-u.ac.jp> 3674 3675 [gxvalid] make the `prop' validation tracing verbose. 3676 3677 * src/gxvalid/gxvprop.c: Add tracing messages for errors. 3678 3679 2011-06-19 suzuki toshiya <mpsuzuki (a] hiroshima-u.ac.jp> 3680 3681 [autogen.sh] Reflect environment variable LIBTOOLIZE. 3682 3683 2011-06-18 Werner Lemberg <wl (a] gnu.org> 3684 3685 Update license documentation. 3686 3687 * docs/GPL.TXT: Renamed to... 3688 * docs/GPLv2.TXT: This. 3689 3690 * docs/LICENSE.TXT: Updated. 3691 3692 2011-06-14 suzuki toshiya <mpsuzuki (a] hiroshima-u.ac.jp> 3693 3694 Fix g++4.6 compiler warnings in module drivers. 3695 3696 The background is same with previous commit. 3697 3698 * src/truetype/ttgxvar.c (ft_var_readpackedpoints): 3699 Init `points'.

At the same time, 4421 try to provide sane values which hopefully allow useful 4422 continuation. Exception to this is CALL and LOOPCALL due to 4423 possible stack corruption it is necessary to bail out. 4424 4425 2011-01-31 Werner Lemberg <wl (a] gnu.org> 4426 4427 [truetype] Improve handling of stack underflow. 4428 4429 * src/truetype/ttinterp.c (TT_RunIns, Ins_FLIPPT, Ins_DELTAP, 4430 Ins_DELTAC): Exit with error only if `pedantic_hinting' is set. 4431 Otherwise, try to do something sane. 4432 4433 2011-01-30 Werner Lemberg <wl (a] gnu.org> 4434 4435 * src/sfnt/ttmtx.c (tt_face_load_hmtx): Fix tracing message. 4436 4437 2011-01-30 LIU Sun-Liang <sunliang_liu (a] foxitsoftware.com> 4438 4439 [truetype]: Fix behaviour of MIAP for invalid arguments. 4440 4441 * src/truetype/ttinterp.c (Ins_MIAP): Set reference points even in 4442 case of error. 4443 4444 2011-01-18 Werner Lemberg <wl (a] gnu.org> 4445 4446 [truetype] Fix handling of MIRP instruction. 4447 4448 Thanks to Greg Hitchcock who explained the issue. 4449 4450 * src/truetype/ttinterp.c (Ins_MIRP): Replace a `>=' operator with 4451 `>' since the description in the specification is incorrect. 4452 This fixes, for example, glyph `two' in font `Helvetica Neue LT Com 4453 65 medium' at 15ppem. 4454 4455 2011-01-15 suzuki toshiya <mpsuzuki (a] hiroshima-u.ac.jp> 4456 4457 Fix ARM assembly code in include/freetype/config/ftconfig.h. 4458 4459 * include/freetype/config/ftconfig.h (FT_MulFix_arm): 4460 Copy the maintained code from builds/unix/ftconfig.in. 4461 Old GNU binutils could not accept the reduced syntax 4462 `orr %0, %2, lsl #16'. Un-omitted syntax like RVCT, 4463 `orr %0, %0, %2, lsl #16' is better. Reported by 4464 Johnson Y. Yan. The bug report by Qt developers is 4465 considered too. 4466 4467 https://bugreports.qt.io/browse/QTBUG-6521 4468 4469 2011-01-15 Werner Lemberg <wl (a] gnu.org> 4470 4471 [raster] Make bbox handling the same as with Microsoft's rasterizer. 4472 4473 Right before B/W rasterizing, the bbox gets simply rounded to 4474 integers. This fixes, for example, glyph `three' in font `Helvetica 4475 Neue LT Com 65 Medium' at 11ppem. 4476 4477 Thanks to Greg Hitchcock who explained this behaviour. 4478 4479 * src/raster/ftrend1.c (ft_raster1_render): Implement it. 4480 4481 2011-01-15 suzuki toshiya <mpsuzuki (a] hiroshima-u.ac.jp> 4482 4483 Copy -mcpu=* & -march=* options from CFLAGS to LDFLAGS. 4484 4485 * builds/unix/configure.raw: Consider recent gcc-standard 4486 flags to specify architecture in CFLAGS & LDFLAGS 4487 harmonization. Requested by Savannah bug #32114, to 4488 support multilib feature of BuildRoot SDK correctly. 4489 4490 2011-01-15 suzuki toshiya <mpsuzuki (a] hiroshima-u.ac.jp> 4491 4492 Fix off-by-one bug in CFLAGS & LDFLAGS harmonizer. 4493 4494 * builds/unix/configure.raw: Some important options that 4495 included in CFLAGS but not in LDFLAGS are copied to 4496 LDFLAGS, but the last option in CFLAGS was not checked. 4497 4498 2011-01-13 Werner Lemberg <wl (a] gnu.org> 4499 4500 [raster] Add undocumented drop-out rule to the other bbox side also. 4501 4502 * src/raster/ftraster.c (Vertical_Sweep_Drop, 4503 Horizontal_Sweep_Drop): Implement it. 4504 4505 2011-01-13 Werner Lemberg <wl (a] gnu.org> 4506 4507 [raster] Reduce jitter value. 4508 4509 This catches a rendering problem with glyph `x' from Tahoma at 4510 10ppem. It seems that the increase of the precision in the change 4511 from 2009-06-11 makes a larger jitter value unnecessary. 4512 4513 * src/raster/ftraster.c (Set_High_Precision): Implement it. 4514 4515 2011-01-13 Werner Lemberg <wl (a] gnu.org> 4516 4517 [raster] Handle drop-outs at glyph borders according to Microsoft. 4518 4519 If a drop-out rule would switch on a pixel outside of the glyph's 4520 bounding box, use the right (or top) pixel instead. This is an 4521 undocumented feature, but some fonts like `Helvetica Neue LT Com 65 4522 Medium' heavily rely on it. 4523 4524 Thanks to Greg Hitchcock who explained this behaviour. 4525 4526 * src/raster/ftraster.c (Vertical_Sweep_Drop, 4527 Horizontal_Sweep_Drop): Implement it. 4528 4529 2011-01-09 suzuki toshiya <mpsuzuki (a] hiroshima-u.ac.jp> 4530 4531 [cache] Fix Savannah bug #31923, patch drafted by Harsha. 4532 4533 When a node comparator changes the cached nodes during the 4534 search of a node matching with queried properties, the 4535 pointers obtained before the function should be updated to 4536 prevent the dereference to freed or reallocated nodes. 4537 To minimize the rescan of the linked list, the update is 4538 executed when the comparator notifies the change of cached 4539 nodes. This change depends previous change: 4540 38b272ffbbdaae276d636aec4ef84af407d16181 4541 4542 * src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Rescan the 4543 top node if the cached nodes are changed. 4544 * src/cache/ftccache.c (FTC_Cache_Lookup): Ditto. 4545 4546 2011-01-09 suzuki toshiya <mpsuzuki (a] hiroshima-u.ac.jp> 4547 4548 [cache] Notice if a cache query induced the node list change. 4549 4550 Some node comparators (comparing the cache node contents and the 4551 properties specified by the query) can flush the cache node to 4552 prevent the cache inflation. The change may invalidate the pointers 4553 to the node obtained before the node comparison, so it should be 4554 noticed to the caller. The problem caused by the cache node 4555 changing is reported by Harsha, see Savannah bug #31923. 4556 4557 * src/cache/ftccache.h (FTC_Node_CompareFunc): Add new argument 4558 `FT_Bool* list_changed' to indicate the change of the cached nodes 4559 to the caller. 4560 (FTC_CACHE_LOOKUP_CMP): Watch the change of the cached nodes by 4561 `_list_changed'. 4562 (FTC_CACHE_TRYLOOP_END): Take new macro argument `_list_changed' 4563 and update it when `FTC_Manager_FlushN' flushes any nodes. 4564 4565 * src/cache/ftccback.h (ftc_snode_compare): Updated to fit with new 4566 FTC_Node_CompareFunc type. 4567 (ftc_gnode_compare): Ditto. 4568 4569 * src/cache/ftcbasic.c: Include FT_INTERNAL_OBJECTS_H to use 4570 TRUE/FALSE macros. 4571 (ftc_basic_gnode_compare_faceid): New argument `FT_Bool* 4572 list_changed' to indicate the change of the cache nodes (anyway, it 4573 is always FALSE). 4574 4575 * src/cache/ftccmap.c: Include FT_INTERNAL_OBJECTS_H to use 4576 TRUE/FALSE macros. 4577 (ftc_cmap_node_compare): New argument `FT_Bool* list_changed' to 4578 indicate the change of the cache nodes (anyway, it is always FALSE). 4579 (ftc_cmap_node_remove_faceid): Ditto. 4580 4581 * src/cache/ftccache.c (FTC_Cache_NewNode): Pass a NULL pointer to 4582 `FTC_CACHE_TRYLOOP_END', because the result is not needed. 4583 (FTC_Cache_Lookup): Watch the change of the cache nodes by 4584 `list_changed'. 4585 (FTC_Cache_RemoveFaceID): Ditto. 4586 4587 * src/cache/ftcglyph.c: Include FT_INTERNAL_OBJECTS_H to use 4588 TRUE/FALSE macros. 4589 (ftc_gnode_compare): New argument `FT_Bool* list_changed' to 4590 indicate the change of the cache nodes (anyway, it is always FALSE). 4591 (FTC_GNode_Compare): New argument `FT_Bool* list_changed' to be 4592 passed to `ftc_gnode_compare'. 4593 * src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto. 4594 4595 * src/cache/ftcsbits.c (ftc_snode_compare): New argument `FT_Bool* 4596 list_changed' to indicate the change of the cache nodes, anyway. It 4597 is updated by `FTC_CACHE_TRYLOOP'. 4598 (FTC_SNode_Compare): New argument `FT_Bool* list_changed' to be 4599 passed to `ftc_snode_compare'. 4600 * src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto. 4601 4602 2011-01-09 suzuki toshiya <mpsuzuki (a] hiroshima-u.ac.jp> 4603 4604 [cache] Fit `FTC_GNode_Compare' to `FTC_Node_CompareFunc'. 4605 4606 * src/cache/ftcglyph.h (FTC_GNode_Compare): Add the 3rd 4607 argument `FTC_Cache cache' to fit FTC_Node_CompareFunc 4608 prototype. 4609 * src/cache/ftcglyph.c (FTC_GNode_Compare): Ditto.

This caused FreeType to 6165 raise an error, because the `setcurrentpoint' operator is only 6166 supposed to be used with the results from an OtherSubr subroutine. 6167 6168 This was fixed by simply ignoring the error and carrying on. 6169 6170 Now we have found a font which uses setcurrentpoint to actually 6171 establish a non-zero point for a contour during the course of a 6172 glyph program. FWIW, these files may be produced by an application 6173 called `Intaglio' on the Mac, when converting TrueType fonts to 6174 Type 1. 6175 6176 The fix allows the new invalid behaviour, the old invalid behaviour 6177 and real proper usage of the operator to work the same way as Adobe 6178 interpreters apparently do. 6179 6180 * src/psaux/t1decode.c (t1_decoder_parse_charstrings): Make 6181 `setcurrentpoint' use the top two elements of the stack to establish 6182 unconditionally the current x and y coordinates. 6183 6184 Make the `flex' subroutine handling (OtherSubr 0) put the current 6185 x,y coordinates onto the stack, instead of two dummy uninitialised 6186 values. 6187 6188 2010-04-14 Ken Sharp <ken.sharp (a] artifex.com> 6189 6190 [psaux] Fix Savannah bug #29444. 6191 6192 * src/psaux/psobjs.c (t1_builder_start_point): Accept (invalid) 6193 `lineto' immediately after `hsbw', in accordance with Acrobat, GS, 6194 and others. 6195 6196 2010-04-14 Micha Cicho <thedmd (a] artifexmundi.com> 6197 6198 [psaux] Fix Savannah bug #27999. 6199 6200 * src/cache/ftcmanag.c (FTC_Manager_RemoveFaceID): Only remove 6201 selected entry, not all. 6202 6203 2010-04-06 Jonathan Kew <jfkthame (a] gmail.com> 6204 6205 [truetype] Add overflow check to `fvar' table. 6206 6207 * src/truetype/ttgxvar.c (TT_Get_MM_Var): Check axis and instance 6208 count. 6209 6210 2010-04-05 Ken Sharp <ken.sharp (a] artifex.com> 6211 6212 [raster] Fix Savannah bug #29335. 6213 6214 * src/raster/ftraster.c (Line_Up): Use slow multiplication to 6215 prevent overflow.
