pango.FontMetrics an object containing overall metric information for a font. pango.FontMetrics gobject.GBoxed get_ascent get_descent get_approximate_char_width get_approximate_digit_width A pango.FontMetrics object holds the overall metric information for a font. A pango.FontMetrics object is returned from the following methods: pango.Context.get_metrics() pango.Font.get_metrics() pango.Fontset.get_metrics() get_ascent Returns : the ascent in pango units. (1 point == pango.SCALE pango units.) The get_ascent() method returns the font ascent in pango units where one font point is equal to pango.SCALE (1024) pango units. The ascent is the distance from the baseline to the logical top of a line of text. (The logical top may be above or below the top of the actual drawn ink. It is necessary to lay out the text to figure where the ink will be.) get_descent Returns : the descent in pango units. (1 point == pango.SCALE pango units.) The get_descent() method returns the font descent in pango units where one font point is equal to pango.SCALE (1024) pango units. The descent is the distance from the baseline to the logical bottom of a line of text. (The logical bottom may be above or below the bottom of the actual drawn ink. It is necessary to lay out the text to figure where the ink will be.) get_approximate_char_width Returns : the character width in pango units. (1 point == pango.SCALE pango units.) The get_approximate_char_width() method returns the approximate character width for a font in pango units where one font point is equal to pango.SCALE (1024) pango units. This is merely a representative value that is useful, for example, for determining the initial size for a window. Actual characters in text will be wider and narrower than this. get_approximate_digit_width Returns : the digit width in pango units. (1 point == pango.SCALE pango units.) The get_approximate_digit_width() method returns the approximate digit width for a font in pango units where one font point is equal to pango.SCALE (1024) pango units. This is merely a representative value that is useful, for example, for determining the initial size for a window. Actual digits in text can be wider and narrower than this, though this value is generally somewhat more accurate than the result of the get_approximate_char_width() method.
