true if found script/language-specific font extents.otLayoutGetFontExtents2
fn
harfbuzz.types.Bool otLayoutGetFontExtents2(harfbuzz.font.Font font, harfbuzz.types.Direction direction, harfbuzz.types.Script script, harfbuzz.types.Language language, out harfbuzz.types.FontExtents extents)Fetches script/language-specific font extents. These values are looked up in the BASE table's MinMax records.
If no such extents are found, the default extents for the font are fetched. As such, the return value of this function can for the most part be ignored. Note that the per-script/language extents do not have a line-gap value, and the line-gap is set to zero in that case.
This function is like [harfbuzz.global.otLayoutGetFontExtents] but takes #hb_script_t and #hb_language_t instead of OpenType #hb_tag_t.
Parameters
font | a font |
direction | text direction. |
script | script. |
language | language. |
extents | font extents if found. |
