);

Parameter descriptions

info

Pointer to a font information structure that contains the font measurement information, in integer values.

DISCUSSION

The GetFontInfo function returns the ascent, descent, leading, and width of the largest glyph of the font in the text font, size, and style specified in the current graphics port. If the script system specified by the current graphics port txFont field has an associated font, as do Hebrew and Arabic, GetFontInfo returns combined information based on both fonts. This is to accommodate text written in the Roman script when the primary script system is non-Roman. However, even if all of the text is written in a non-Roman script, if there is an associated font, GetFontInfo always bases its information on the combined fonts. You can determine the line height, in pixels, by adding the values of the ascent, descent, and leading fields.

The GetFontInfo function is similar to the Font Manager’s FontMetrics function, except that the GetFontInfo function returns integer values. See FontInfo for a description of the structure and its fields.
