Hi,
Do I only need to call FcConfigDestroy to destroy the config, pattern, objectset and the fontset or I need to call them all like I am currently doing?
fonts_filename = set()
config = LinuxFonts._font_config.FcInitLoadConfigAndFonts()
pat = LinuxFonts._font_config.FcPatternCreate()
os = LinuxFonts._font_config.FcObjectSetBuild(b"file", b"fontformat", 0)
fs = LinuxFonts._font_config.FcFontList(config, pat, None)
for i in range(fs.contents.nfont):
font = fs.contents.fonts[i]
file_path_ptr = c_char_p()
font_format_ptr = c_char_p()
if (
LinuxFonts._font_config.FcPatternGetString(font, b"fontformat", 0, byref(font_format_ptr)) == FC_RESULT.FC_RESULT_MATCH
and LinuxFonts._font_config.FcPatternGetString(font, b"file", 0, byref(file_path_ptr)) == FC_RESULT.FC_RESULT_MATCH
):
font_format = FT_FONT_FORMAT(font_format_ptr.value)
if font_format in LinuxFonts.VALID_FONT_FORMATS:
# Decode with utf-8 since FcChar8
fonts_filename.add(file_path_ptr.value.decode())
# I am not 100% if we need to call all of these. We may only need to call FcFontSetDestroy.
LinuxFonts._font_config.FcConfigDestroy(config)
LinuxFonts._font_config.FcPatternDestroy(pat)
LinuxFonts._font_config.FcObjectSetDestroy(os)
LinuxFonts._font_config.FcFontSetDestroy(fs)
The full code is available here
