Implements org.lwjgl.util.harfbuzz.hb_font_get_glyph_extents_func_tI.invoke.

Doc from org.lwjgl.util.harfbuzz.hb_font_get_glyph_extents_func_tI.invoke.

A virtual method for the hb_font_funcs_t of an hb_font_t object.

This method should retrieve the extents for a specified glyph. Extents must be returned in an hb_glyph_extents output parameter.

Return value: true if data found, false otherwise.

Parameters
font:long

hb_font_t to work upon

font_data:long

font user data pointer

glyph:int

the glyph ID to query

extents:long

the hb_glyph_extents_t retrieved

user_data:long

user data pointer passed by the caller
