hb_font_get_glyph_func_t

typedef hb_bool_t(* hb_font_get_glyph_func_t) (hb_font_t *font, void *font_data, hb_codepoint_t unicode, hb_codepoint_t variation_selector, hb_codepoint_t *glyph, void *user_data)

A virtual method for the hb_font_funcs_t of an hb_font_t object.

This method should retrieve the glyph ID for a specified Unicode code point font, with an optional variation selector.

Return value: true if data found, false otherwise Deprecated: 1.2.3

Definition at line 100 of file hb-deprecated.h.

hb_font_get_glyph_shape_func_t

hb_font_get_glyph_shape_func_t: @font: hb_font_t to work upon @font_data: @font user data pointer @glyph: The glyph ID to query @draw_funcs: The draw functions to send the shape data to @draw_data: The data accompanying the draw functions @user_data: User data pointer passed by the caller

A virtual method for the hb_font_funcs_t of an hb_font_t object.

hb_font_get_glyph_v_kerning_func_t

typedef hb_font_get_glyph_kerning_func_t hb_font_get_glyph_v_kerning_func_t

hb_font_get_glyph_v_kerning_func_t:

A virtual method for the hb_font_funcs_t of an hb_font_t object.

This method should retrieve the kerning-adjustment value for a glyph-pair in the specified font, for vertical text segments.

Definition at line 235 of file hb-deprecated.h.

hb_unicode_decompose_compatibility_func_t

typedef unsigned int(* hb_unicode_decompose_compatibility_func_t) (hb_unicode_funcs_t *ufuncs, hb_codepoint_t u, hb_codepoint_t *decomposed, void *user_data)

hb_unicode_decompose_compatibility_func_t: @ufuncs: a Unicode function structure @u: codepoint to decompose @decomposed: address of codepoint array (of length HB_UNICODE_MAX_DECOMPOSITION_LEN) to write decomposition into @user_data: user data pointer as passed to hb_unicode_funcs_set_decompose_compatibility_func()

Fully decompose @u to its Unicode compatibility decomposition. The codepoints of the decomposition will be written to @decomposed. The complete length of the decomposition will be returned.

If @u has no compatibility decomposition, zero should be returned.

The Unicode standard guarantees that a buffer of length HB_UNICODE_MAX_DECOMPOSITION_LEN codepoints will always be sufficient for any compatibility decomposition plus an terminating value of 0. Consequently, @decompose must be allocated by the caller to be at least this length. Implementations of this function type must ensure that they do not write past the provided array.

Return value: number of codepoints in the full compatibility decomposition of @u, or 0 if no decomposition available.

hb_unicode_eastasian_width_func_t: @ufuncs: A Unicode-functions structure @unicode: The code point to query @user_data: User data pointer passed by the caller

A virtual method for the hb_unicode_funcs_t structure.
