FontConfigSubstitutionRule class

FontConfigSubstitutionRule class

Font config substitution rule. To learn more, visit the Working with Fonts documentation article.

Remarks

This rule uses fontconfig utility on Linux (and other Unix-like) platforms to get the substitution if the original font is not available.

If fontconfig utility is not available then this rule will be ignored.

Inheritance: FontConfigSubstitutionRule → FontSubstitutionRule

Properties

Name	Description
enabled	Specifies whether the rule is enabled or not.

Methods

Name	Description
is_font_config_available()	Check if fontconfig utility is available or not.
reset_cache()	Resets the cache of fontconfig calling results.

Examples

Shows operating system-dependent font config substitution.

font_settings = aw.fonts.FontSettings()
font_config_substitution = font_settings.substitution_settings.font_config_substitution
# The FontConfigSubstitutionRule object works differently on Windows/non-Windows platforms.
# On Windows, it is unavailable.
if platform.system() == 'Windows':
    self.assertFalse(font_config_substitution.enabled)
    self.assertFalse(font_config_substitution.is_font_config_available())
else:
    # On Linux/Mac, we will have access to it, and will be able to perform operations.
    self.assertTrue(font_config_substitution.enabled)
    self.assertTrue(font_config_substitution.is_font_config_available())
    font_config_substitution.reset_cache()
