* Let FT handle the memory management for rendering port's stateMoazin Khatti2019-07-115-35/+126
| | | | | | | | | | | | | | | | | | | | | | | | | and the image buffer. State has been moved inside the library structure. A new hook function has been added to query the size needed for the state structure and this allocation is performed by FT. Memory alloc. for the image buffer is also being done by FT so that it can later free it easily. * include/freetype/svgrenderer.h: Small doc fixes. Addition of two new hooks. `SVG_Lib_Get_State_Size' and `SVG_Lib_Get_Buffer_Size'. * src/base/ftglyph.c (FT_Glyph_To_Bitmap): Small bug fix. Memory was being initialized before library. * src/base/ftobjs.c (FT_Set_Svg_Hooks): Adjust the code for new hook functions. * src/svg/ftsvg.c: Adjust the code for new hook functions. Perform all memory allocations needed by the rendering port from FreeType side. * src/svg/svgtypes.c: Add the new hooks in the hook structure.
* Store the rendering port's state in library.Moazin Khatti2019-07-114-14/+41
| | | | | Before this commit, the state of a rendering port was being held globally. Now, it'll be stored in library->svg_renderer_state.
* Minor fixes.Moazin Khatti2019-07-1115-36/+49
|
* Add `start_glyph_id' and `end_glyph_id'.Moazin Khatti2019-07-114-2/+38
| | | | | | These two fields are added to `FT_SvgGlyphRec' and `FT_SVG_DocumentRec'. This is to allow the rendering port to create a caching mechanism.
* Add a `units_per_EM' field.Moazin Khatti2019-07-114-0/+34
| | | | | | | | | A field `units_per_EM' is added to `FT_SVG_DocumentRec' and `FT_SvgGlyphRec'. This is needed because the renderer needs this info to properly scale the SVGs if the viewbox width and height differ from `face->units_per_EM'. Face object can't be accessed because of the restrictions put by `FT_Glyph_To_Bitmap' thus this has to be provided separately just like `metrics'.
* Do proper memory freeing to prevent leaks.Moazin Khatti2019-07-114-4/+28
| | | | | | | | | | | | | | * include/freetype/internal/ftobjs.h: Create a new flag named `FT_GLYPH_OWN_GZIP_SVG' to indicate that `svg_document' in `slot->other' is GZIP compressed and has to be freed later. * src/base/ftglyph.c: Minor styling. * src/base/ftobjs.c: Add code to free memory that was previously allocated for storing GZIP compressed SVG documents. * src/sfnt/ttsvg.c: Set the `FT_GLYPH_OWN_GZIP_SVG' flag if the document is GZIP compressed.
* Minor. Add documentation.Moazin Khatti2019-07-112-0/+5

* Properly free memory of SVG document referenced in `slot->other'.Moazin Khatti2019-07-113-5/+24
| | | | | | | | | | | | | | | | * include/freetype/freetype.h: Add `FT_FACE_FLAG_SVG' to indicate the presence of an SVG table in the face. * src/base/ftobjs.c (ft_glyphslot_init): Allocate memory for `FT_SVG_Document' in `slot->other' if an SVG table exists in the face. (ft_glyphslot_clear): Clear `slot->other' only if the font doesn't have an SVG table. (ft_glyphslot_done): Free the memory at `slot->other' if the face has an SVG table. * src/base/ttsvg.c (tt_face_load_svg): Set `FT_FACE_FLAG_SVG'. (tt_face_load_svg_doc): Don't allocate the memory.

| | | | | | | | | | | | * src/base/ftobjs.c (FT_Load_Glyph): Use the recrusive call with `FT_LOAD_NO_SCALE' so that the loaded data is unscaled. * src/base/ftobjs.c (FT_Render_Glyph_Internal): Change the format to bitmap once an SVG glyph is successfully rendered. * src/sfnt/ttsvg.c (tt_face_load_svg_doc): Make sure metrics are grabbed. Scale `horiAdvance' and `vertAdvance' properly and convert them to 26.6 format.
* Adds support for SVG glyphs to Glyph Management API.Moazin Khatti2019-07-112-0/+202

* Make sure `FT_Set_Svg_Hooks' is exported properly.Moazin Khatti2019-07-111-1/+1
|
* Adds size information to `FT_SVG_DocumentRec'.Moazin Khatti2019-07-111-2/+3
| | | | | | | | | | | This is necessary because the document itself contains no sizing information. Outline glyphs encapsulate the sizing information in the outlines by scaling them. That is not possible here. One could access them from the face object reference inside a glyph slot, but when the function `FT_Glyph_To_Bitmap' creates a dummy slot it can not put a face object reference in it. Thus, it's better to store the size information here.

Adds a hook for svg rendering. Temporary.

* [psaux] (2/2) Handle fonts that use SEAC for ligatures (#56580).Werner Lemberg2019-07-042-6/+23
| | | | | | The same as previous commit but for the old engine. * src/psaux/t1decode.c (t1operator_seac): Implement it.
* [psaux] (1/2) Handle fonts that use SEAC for ligatures (#56580).Chris Liddell2019-07-042-6/+37
| | | | | | | | | | | | | | | | | | | As originally intended, a Type 1 SEAC charstring would be used for an accented glyph (like `acaron' or `uumlaut'), where the advance width of the SEAC glyph is the same as that of the `base' glyph (like `a' or `u'). In this case it is not uncommon for the SEAC glyph to not use an (H)SBW opcode of its own but to rely on the value from the base glyph. However, out-of-spec fonts also use SEAC glyphs for ligatures (like `oe' or `fi'), and in those cases the overall advance width is greater than that of the `base' glyph. For this reason we have to allow that the SEAC glyph can have an (H)SBW value of its own, and if it has, retain this value, rather than the one from the base glyph. * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_escSEAC>: Implement it.

* [smooth] Restore the span buffering for direct mode only.Alexei Podtelezhnikov2019-06-132-6/+39
| | | | | | | | | | | | The buffer size FT_MAX_GRAY_SPANS is set to 10 spans, which should be enough to cover the entire scanline for simple glyphs in most cases: each slightly slanted edge needs up to two spans, plus a filling span in-between. This is not new, we used to do it before cb4388783cecc. * src/smooth/ftgrays.c (gray_TWorker): Add `spans' and `num_spans'. (gray_hline, gray_sweep): Implement the span buffering. (gray_raster_render): Use negative `num_spans' to avoid the direct mode.
