The result is the absolute value of the difference between theĬSS numeric values of stretch1 and stretch2, normalizedīetween 0.0 and 1.0. Return a match score between stretch1 and stretch2. Size2, normalized so that the usual range of font sizes (6pt -ħ2pt) will lie between 0.0 and 1.0. Otherwise, the result is the absolute distance between size1 and If size2 (the size specified in the font file) is 'scalable', thisįunction always returns 0.0, since any font size can be generated. Return a match score between size1 and size2.
Return a match score between the list of font families inįamilies and the font family name family2.Īn exact match at the head of the list returns 0.0.Ī match further down the list will return between 0 and 1. See the W3C Cascading Style Sheet, Level 1 documentationįor a description of the font finding algorithm.
Perform the O(n) nearest neighbor search. The result is cached, so subsequent lookups don't have to Threshold are found, the default font (usually DejaVu Sans) is Similarity score to the target font properties. Match appears to point to a nonexisting font (i.e., the font cache Whether to rebuild the font cache and search again if the first "DejaVu Sans" or "Helvetica") if the first lookup hard-fails. If True, will fallback to the default font family (usually If given, only search this directory and its subdirectories.
This can be either aįontProperties object or a string defining aįontconfig patterns. Property defaultFont ¶ findfont ( prop, fontext = 'ttf', directory = None, fallback_to_default = True, rebuild_if_missing = True ) ¶įind a font that most closely matches the given font properties. The type of font is inferred from the path suffix. addfont ( path ) ¶Ĭache the properties of the font at path to make it available to theįontManager. If no good enough match is found, the defaultįont is returned. Method does a nearest neighbor search to find the font that most closely On import, the FontManager singleton instance creates a list of ttf andĪfm fonts and caches their FontProperties.
