Gets the approximate character width for a font metrics structure. This is merely a representative value useful, for example, for determining the initial size for a window. Actual characters in text will be wider and narrower than this.
|
|
Gets the approximate digit width for a font metrics structure. This is merely a representative value 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 pango_font_metrics_get_approximate_digit_width().
|
|
Gets the ascent from a font metrics structure. 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.)

Gets the descent from a font metrics structure. 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.)
|
|
Gets the suggested position to draw the strikethrough. The value returned is the distance above the baseline of the top of the strikethrough.
|
|
Gets the suggested thickness to draw for the strikethrough.
|
|
Gets the suggested position to draw the underline. The value returned is the distance above the baseline of the top of the underline. Since most fonts have underline positions beneath the baseline, this value is typically negative.
|
|
Gets the suggested thickness to draw for the underline.
