Moazin Khatti c25304fa34 Documentation formatting improvement. 2019-08-17 20:36:05 +05:00
Moazin Khatti c6a6859ad9 Better naming used. 2019-08-17 20:36:05 +05:00
Moazin Khatti fbdd9f9ba3 Memory allocation for `state' of renderer should be performed
on the SVG port side not the FT size. Minor doc fixes.
2019-08-17 20:36:05 +05:00
Moazin Khatti 1f74524929 Let FT handle the memory management for rendering port's state
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.

Moazin Khatti de44a3fda8 Store the rendering port's state in library.
Before this commit, the state of a rendering port was being
held globally. Now, it'll be stored in library->svg_renderer_state.

Moazin Khatti e028be97b8 Minor fixes. 2019-08-17 20:36:05 +05:00
Moazin Khatti d8202166c0 Add `start_glyph_id' and `end_glyph_id'.
These two fields are added to `FT_SvgGlyphRec' and
`FT_SVG_DocumentRec'. This is to allow the rendering port to create
a caching mechanism.
2019-08-17 20:36:05 +05:00
Moazin Khatti e48cf716f8 Add a `units_per_EM' field.
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'.
2019-08-17 20:36:05 +05:00
Moazin Khatti 7275d6562f Do proper memory freeing to prevent leaks.
* 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.
2019-08-17 20:36:05 +05:00
Moazin Khatti 22988063b0 Minor. Add documentation. 2019-08-17 20:36:05 +05:00
Moazin Khatti 6a39dd0b16 Properly free memory of SVG document referenced in `slot->other'.
* 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.

Moazin Khatti 1e6cfffcb2 Enable FreeType memory debugger. 2019-08-17 20:36:05 +05:00
Moazin Khatti 6bf9ade45c Adds support for SVG glyphs to Glyph Management API. 2019-08-17 20:36:05 +05:00
Moazin Khatti 61b1f0b73c Make sure `FT_Set_Svg_Hooks' is exported properly. 2019-08-17 20:36:05 +05:00
Moazin Khatti 294a7ebee2 Adds size information to `FT_SVG_DocumentRec'.
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.

for `freetype/svgrenderer.h'.

* include/freetype/svgrenderer.h: New file to store SVG specific
function types, SVG interface and `FT_Set_Svg_Hooks'.

* src/base/ftobjs.c: Adds implementation of `FT_Set_Svg_Hooks'.

* src/svg/ftsvg.c: Creates `svg_renderer_interface'.

* src/svg/svgtypes.c: Moves hook function types to
`FT_SVG_RENDERER_H'. Adds a hook for svg rendering. Temporary.
