IMPORTANT BUG FIXES + + - Loading CFF fonts sometimes made FreeType crash (bug introduced in + version 2.12.0) + + - Loading a fully hinted TrueType glyph a second time (without + caching) sometimes yielded different rendering results if TrueType + hinting was active (bug introduced in version 2.12.0). + + - The generation of the pkg-config file `freetype2.pc` was broken if + the build was done with cmake (bug introduced in version 2.12.0). + + + II. MISCELLANEOUS + + - New option `--with-librsvg` for the `configure` script for better + FreeType demo support. + + - The meson build no longer enforces both static and dynamic + versions of the library by default. + + - The internal zlib library was updated to version 1.2.12. Note, + however, that FreeType is *not* affected by CVE-2018-25032 since + it only does decompression. + + +====================================================================== + +CHANGES BETWEEN 2.11.1 and 2.12.0 + + I. IMPORTANT CHANGES + + - FreeType now handles OT-SVG fonts, to be controlled with + `FT_CONFIG_OPTION_SVG` configuration macro. By default, it can + only load the 'SVG ' table of an OpenType font. However, by using + the `svg-hooks` property of the new 'ot-svg' module it is possible + to register an external SVG rendering engine. The FreeType demo + programs have been set up to use 'librsvg' as the rendering + library. + + This work was Moazin Khatti's GSoC 2019 project. + + + II. MISCELLANEOUS + + - The handling of fonts with an 'sbix' table has been improved. + + - Corrected bitmap offsets. + + - A new tag `FT_PARAM_TAG_IGNORE_SBIX` for `FT_Open_Face` makes + FreeType ignore an 'sbix' table in a font, allowing applications + to access the font's outline glyphs. + + - `FT_FACE_FLAG_SBIX` and `FT_FACE_FLAG_SBIX_OVERLAY` together + with their corresponding preprocessor macros `FT_HAS_SBIX` and + `FT_HAS_SBIX_OVERLAY` enable applications to treat 'sbix' tables + as described in the OpenType specification. + + - The internal 'zlib' code has been updated to be in sync with the + current 'zlib' version (1.2.11). + + - The previously internal load flag `FT_LOAD_SBITS_ONLY` is now + public. + + - Some minor improvements of the building systems, in particular + handling of the 'zlib' library (internal vs. external). + + - Support for non-desktop Universal Windows Platform. + + - Various other minor bug and documentation fixes. + + - The `ftdump` demo program shows more information for Type1 fonts + if option `-n` is given. + + - `ftgrid` can now display embedded bitmap strikes. + + +====================================================================== + +CHANGES BETWEEN 2.11.0 and 2.11.1 + + I. IMPORTANT CHANGES + + - Some fields in the `CID_FaceDictRec`, `CID_FaceInfoRec`, and + `FT_Data` structures have been changed from signed to unsigned + type, which better reflects the actual usage. It is also an + additional means to protect against malformed input. + + + II. MISCELLANEOUS + + - Cmake support has been further improved. To do that various + backward-incompatible changes were necessary; please see file + `CMakeLists.txt` for more details. + + - Since version 2.11.0, a C99 compiler is necessary to compile + FreeType. + + - The experimental 'COLR' v1 API has been updated to the latest + OpenType standard 1.9. + + - The `apinames` tool got a new option `-wV` to output an OpenVMS + Linker Option File. + + - VMS support was updated. + + - MS Visual Studio support was added to build the demo programs. + + +====================================================================== + +CHANGES BETWEEN 2.10.4 and 2.11.0 + + I. IMPORTANT CHANGES + + - A new rendering module has been added to create 8-bit Signed + Distance Field (SDF) bitmaps for both outline and bitmap glyphs. + The new rendering mode is called `FT_RENDER_MODE_SDF`, the pixel + mode is `FT_PIXEL_MODE_GRAY8`, and the corresponding raster flag + is `FT_RASTER_FLAG_SDF`. + + This work was Anuj Verma's GSoC 2020 project. + + - A new, experimental API is now available for surfacing properties + of 'COLR' v1 color fonts (as the name says, this is an extension + to the 'COLR' table for outline color fonts using the SFNT + container format). 'COLR' v1 fonts are a recently proposed + addition to OFF and OpenType; specification work currently happens + in + + https://github.com/googlefonts/colr-gradients-spec/ + + 'COLR' v1 is expected to be merged to OpenType; the ISO + standardisation process for adding 'COLR' v1 as an amendment to + OFF is underway. + + Functions similar to the already existing 'COLR' API have been + added to access the corresponding data. + + FT_Get_Color_Glyph_Paint + Retrieve the root paint for a given glyph ID. + + FT_Get_Paint_Layers + Access the layers of a `PaintColrLayers` table. + + FT_Get_Colorline_Stops + Retrieve the 'color stops' on a color line. As an input, a + color stop iterator gets used, which in turn is retrieved from + a paint. + + FT_Get_Paint + Dereference an `FT_OpaquePaint` object and retrieve the + corresponding `FT_COLR_Paint` object, which contains details + on how to draw the respective 'COLR' v1 `Paint` table. + + + II. MISCELLANEOUS + + - FreeType has moved its infrastructure to + + https://gitlab.freedesktop.org/freetype + + A side effect is that the git repositories are now called + `freetype.git` and `freetype-demos.git`, which by default expand + to the directories `freetype` and `freetype-demos`, respectively. + The documentation has been updated accordingly. + + FreeType's Savannah repositories will stay; they are now mirrors + of the 'freedesktop.org' repositories. + + - A new function `FT_Get_Transform` returns the values set by + `FT_Set_Transform`. + + - A new configuration macro `FT_DEBUG_LOGGING` is available. It + provides extended debugging capabilities for FreeType, for example + showing a time stamp or displaying the component a tracing message + comes from. See file `docs/DEBUG` for more information. + + This work was Priyesh Kumar's GSoC 2020 project. + + - The legacy Type 1 and CFF engines are further demoted due to lack + of CFF2 charstring support.

history: + * + * 1.2.beta0 24 Nov 2002 + * - First version -- complete rewrite of inflate to simplify code, avoid + * creation of window when not needed, minimize use of window when it is + * needed, make inffast.c even faster, implement gzip decoding, and to + * improve code readability and style over the previous zlib inflate code + * + * 1.2.beta1 25 Nov 2002 + * - Use pointers for available input and output checking in inffast.c + * - Remove input and output counters in inffast.c + * - Change inffast.c entry and loop from avail_in >= 7 to >= 6 + * - Remove unnecessary second byte pull from length extra in inffast.c + * - Unroll direct copy to three copies per loop in inffast.c + * + * 1.2.beta2 4 Dec 2002 + * - Change external routine names to reduce potential conflicts + * - Correct filename to inffixed.h for fixed tables in inflate.c + * - Make hbuf[] unsigned char to match parameter type in inflate.c + * - Change strm->next_out[-state->offset] to *(strm->next_out - state->offset) + * to avoid negation problem on Alphas (64 bit) in inflate.c + * + * 1.2.beta3 22 Dec 2002 + * - Add comments on state->bits assertion in inffast.c + * - Add comments on op field in inftrees.h + * - Fix bug in reuse of allocated window after inflateReset() + * - Remove bit fields--back to byte structure for speed + * - Remove distance extra == 0 check in inflate_fast()--only helps for lengths + * - Change post-increments to pre-increments in inflate_fast(), PPC biased? + * - Add compile time option, POSTINC, to use post-increments instead (Intel?) + * - Make MATCH copy in inflate() much faster for when inflate_fast() not used + * - Use local copies of stream next and avail values, as well as local bit + * buffer and bit count in inflate()--for speed when inflate_fast() not used + * + * 1.2.beta4 1 Jan 2003 + * - Split ptr - 257 statements in inflate_table() to avoid compiler warnings + * - Move a comment on output buffer sizes from inffast.c to inflate.c + * - Add comments in inffast.c to introduce the inflate_fast() routine + * - Rearrange window copies in inflate_fast() for speed and simplification + * - Unroll last copy for window match in inflate_fast() + * - Use local copies of window variables in inflate_fast() for speed + * - Pull out common wnext == 0 case for speed in inflate_fast() + * - Make op and len in inflate_fast() unsigned for consistency + * - Add FAR to lcode and dcode declarations in inflate_fast() + * - Simplified bad distance check in inflate_fast() + * - Added inflateBackInit(), inflateBack(), and inflateBackEnd() in new + * source file infback.c to provide a call-back interface to inflate for + * programs like gzip and unzip -- uses window as output buffer to avoid + * window copying + * + * 1.2.beta5 1 Jan 2003 + * - Improved inflateBack() interface to allow the caller to provide initial + * input in strm. + * - Fixed stored blocks bug in inflateBack() + * + * 1.2.beta6 4 Jan 2003 + * - Added comments in inffast.c on effectiveness of POSTINC + * - Typecasting all around to reduce compiler warnings + * - Changed loops from while (1) or do {} while (1) to for (;;), again to + * make compilers happy + * - Changed type of window in inflateBackInit() to unsigned char * + * + * 1.2.beta7 27 Jan 2003 + * - Changed many types to unsigned or unsigned short to avoid warnings + * - Added inflateCopy() function + * + * 1.2.0 9 Mar 2003 + * - Changed inflateBack() interface to provide separate opaque descriptors + * for the in() and out() functions + * - Changed inflateBack() argument and in_func typedef to swap the length + * and buffer address return values for the input function + * - Check next_in and next_out for Z_NULL on entry to inflate() + * + * The history for versions after 1.2.0 are in ChangeLog in

The NEEDBITS() macro is usually the way the state evaluates + whether it can proceed or should return. NEEDBITS() does the return if + the requested bits are not available. The typical use of the BITS macros + is: + + NEEDBITS(n); + ... do something with BITS(n) ... + DROPBITS(n); + + where NEEDBITS(n) either returns from inflate() if there isn't enough + input left to load n bits into the accumulator, or it continues. BITS(n) + gives the low n bits in the accumulator. When done, DROPBITS(n) drops + the low n bits off the accumulator. INITBITS() clears the accumulator + and sets the number of available bits to zero. BYTEBITS() discards just + enough bits to put the accumulator on a byte boundary. After BYTEBITS() + and a NEEDBITS(8), then BITS(8) would return the next byte in the stream. + + NEEDBITS(n) uses PULLBYTE() to get an available byte of input, or to return + if there is no input available. The decoding of variable length codes uses + PULLBYTE() directly in order to pull just enough bytes to decode the next + code, and no more. + + Some states loop until they get enough input, making sure that enough + state information is maintained to continue the loop where it left off + if NEEDBITS() returns in the loop. For example, want, need, and keep + would all have to actually be part of the saved state in case NEEDBITS() + returns: + + case STATEw: + while (want < need) { + NEEDBITS(n); + keep[want++] = BITS(n); + DROPBITS(n); + } + state = STATEx; + case STATEx: + + As shown above, if the next state is also the next case, then the break + is omitted. + + A state may also return if there is not enough output space available to + complete that state. Those states are copying stored data, writing a + literal byte, and copying a matching string. + + When returning, a "goto inf_leave" is used to update the total counters, + update the check value, and determine whether any progress has been made + during that inflate() call in order to return the proper return code. + Progress is defined as a change in either strm->avail_in or strm->avail_out. + When there is a window, goto inf_leave will update the window with the last + output written. If a goto inf_leave occurs in the middle of decompression + and there is no window currently, goto inf_leave will create one and copy + output to the window for the next call of inflate(). + + In this implementation, the flush parameter of inflate() only affects the + return code (per zlib.h). inflate() always writes as much as possible to + strm->next_out, given the space available and the provided input--the effect + documented in zlib.h of Z_SYNC_FLUSH. Furthermore, inflate() always defers + the allocation of and copying into a sliding window until necessary, which + provides the effect documented in zlib.h for Z_FINISH when the entire input + stream available.

These values may be adjusted either when all of the - codes are shorter than that, in which case the longest code length in - bits is used, or when the shortest code is *longer* than the requested - table size, in which case the length of the shortest code in bits is - used. - - There are two different values for the two tables, since they code a - different number of possibilities each.

For the deflate format, these bits are stored backwards + from their more natural integer increment ordering, and so when the + decoding tables are built in the large loop below, the integer codes + are incremented backwards. + + This routine assumes, but does not check, that all of the entries in + lens[] are in the range 0..MAXBITS. The caller must assure this. + 1..MAXBITS is interpreted as that code length. zero means that that + symbol does not occur in this code. + + The codes are sorted by computing a count of codes for each length, + creating from that a table of starting indices for each length in the + sorted table, and then entering the symbols in order in the sorted + table. The sorted table is work[], with that space being provided by + the caller. + + The length counts are used for other purposes as well, i.e. finding + the minimum and maximum length codes, determining if there are any + codes at all, checking for a valid set of lengths, and looking ahead + at length counts to determine sub-table sizes when building the + decoding tables. + */ + + /* accumulate lengths for codes (assumes lens[] all in 0..MAXBITS) */ + for (len = 0; len <= MAXBITS; len++) + count[len] = 0; + for (sym = 0; sym < codes; sym++) + count[lens[sym]]++; + + /* bound code lengths, force root to be within code lengths */ + root = *bits; + for (max = MAXBITS; max >= 1; max--) + if (count[max] != 0) break; + if (root > max) root = max; + if (max == 0) { /* no symbols to code at all */ + here.op = (unsigned char)64; /* invalid code marker */ + here.bits = (unsigned char)1; + here.val = (unsigned short)0; + *(*table)++ = here; /* make a table to force an error */ + *(*table)++ = here; + *bits = 1; + return 0; /* no symbols, but wait for decoding to report error */ + } + for (min = 1; min < max; min++) + if (count[min] != 0) break; + if (root < min) root = min; + + /* check for an over-subscribed or incomplete set of lengths */ + left = 1; + for (len = 1; len <= MAXBITS; len++) { + left <<= 1; + left -= count[len]; + if (left < 0) return -1; /* over-subscribed */ + } + if (left > 0 && (type == CODES || max != 1)) + return -1; /* incomplete set */ + + /* generate offsets into symbol table for each length for sorting */ + offs[1] = 0; + for (len = 1; len < MAXBITS; len++) + offs[len + 1] = offs[len] + count[len]; + + /* sort symbols by length, by symbol order within each length */ + for (sym = 0; sym < codes; sym++) + if (lens[sym] != 0) work[offs[lens[sym]]++] = (unsigned short)sym; + + /* + Create and fill in decoding tables.

There is another + * renderer called 'sdf', which generates SDF directly from outlines; + * see file `ftsdf.c` for more. + * + * * The idea of generating SDF from bitmaps is taken from two research + * papers, where one is dependent on the other: + * + * - Per-Erik Danielsson: Euclidean Distance Mapping + * http://webstaff.itn.liu.se/~stegu/JFA/Danielsson.pdf + * + * From this paper we use the eight-point sequential Euclidean + * distance mapping (8SED). This is the heart of the process used + * in this rasterizer. + * + * - Stefan Gustavson, Robin Strand: Anti-aliased Euclidean distance transform. + * http://weber.itn.liu.se/~stegu/aadist/edtaa_preprint.pdf + * + * The original 8SED algorithm discards the pixels' alpha values, + * which can contain information about the actual outline of the + * glyph. This paper takes advantage of those alpha values and + * approximates outline pretty accurately. + * + * * This rasterizer also works for monochrome bitmaps. However, the + * result is not as accurate since we don't have any way to + * approximate outlines from binary bitmaps. + * + * ======================================================================== + * + * Generating SDF from bitmap is done in several steps. + * + * (1) The only information we have is the bitmap itself. It can + * be monochrome or anti-aliased. If it is anti-aliased, pixel values + * are nothing but coverage values. These coverage values can be used + * to extract information about the outline of the image. For + * example, if the pixel's alpha value is 0.5, then we can safely + * assume that the outline passes through the center of the pixel. + * + * (2) Find edge pixels in the bitmap (see `bsdf_is_edge` for more). For + * all edge pixels we use the Anti-aliased Euclidean distance + * transform algorithm and compute approximate edge distances (see + * `compute_edge_distance` and/or the second paper for more). + * + * (3) Now that we have computed approximate distances for edge pixels we + * use the 8SED algorithm to basically sweep the entire bitmap and + * compute distances for the rest of the pixels. (Since the algorithm + * is pretty convoluted it is only explained briefly in a comment to + * function `edt8`. To see the actual algorithm refer to the first + * paper.) + * + * (4) Finally, compute the sign for each pixel. This is done in function + * `finalize_sdf`. The basic idea is that if a pixel's original + * alpha/coverage value is greater than 0.5 then it is 'inside' (and + * 'outside' otherwise). + * + * Pseudo Code: + * + * ``` + * b = source bitmap; + * t = target bitmap; + * dm = list of distances; // dimension equal to b + * + * foreach grid_point (x, y) in b: + * { + * if (is_edge(x, y)): + * dm = approximate_edge_distance(b, x, y); + * + * // do the 8SED on the distances + * edt8(dm); + * + * // determine the signs + * determine_signs(dm): + * + * // copy SDF data to the target bitmap + * copy(dm to t); + * } + * + */ + + + /************************************************************************** + * + * The macro FT_COMPONENT is used in trace mode.

There is + * another renderer called 'bsdf', which converts bitmaps to SDF; see + * file `ftbsdf.c` for more. + * + * * The basic idea of generating the SDF is taken from Viktor Chlumsky's + * research paper. The paper explains both single and multi-channel + * SDF, however, this implementation only generates single-channel SDF. + * + * Chlumsky, Viktor: Shape Decomposition for Multi-channel Distance + * Fields. Master's thesis. Czech Technical University in Prague, + * Faculty of InformationTechnology, 2015. + * + * For more information: https://github.com/Chlumsky/msdfgen + * + * ======================================================================== + * + * Generating SDF from outlines is pretty straightforward. + * + * (1) We have a set of contours that make the outline of a shape/glyph. + * Each contour comprises of several edges, with three types of edges. + * + * * line segments + * * conic Bezier curves + * * cubic Bezier curves + * + * (2) Apart from the outlines we also have a two-dimensional grid, namely + * the bitmap that is used to represent the final SDF data. + * + * (3) In order to generate SDF, our task is to find shortest signed + * distance from each grid point to the outline. The 'signed + * distance' means that if the grid point is filled by any contour + * then its sign is positive, otherwise it is negative. The pseudo + * code is as follows. + * + * ``` + * foreach grid_point (x, y): + * { + * int min_dist = INT_MAX; + * + * foreach contour in outline: + * { + * foreach edge in contour: + * { + * // get shortest distance from point (x, y) to the edge + * d = get_min_dist(x, y, edge); + * + * if (d < min_dist) + * min_dist = d; + * } + * + * bitmap[x, y] = min_dist; + * } + * } + * ``` + * + * (4) After running this algorithm the bitmap contains information about + * the shortest distance from each point to the outline of the shape. + * Of course, while this is the most straightforward way of generating + * SDF, we use various optimizations in our implementation. See the + * `sdf_generate_*' functions in this file for all details. + * + * The optimization currently used by default is subdivision; see + * function `sdf_generate_subdivision` for more. + * + * Also, to see how we compute the shortest distance from a point to + * each type of edge, check out the `get_min_distance_*' functions. + * + */ + + + /************************************************************************** + * + * The macro FT_COMPONENT is used in trace mode.
