In addition, the font sample view can display a graphical representation of some of the font metrics. Font metrics are specified by the font's designer to give additional information about spacings and sizes to the font rendering engine.
(For programmers: With &os2;, font metrics are contained in a
FONTMETRICS
structure, which is described in the PM Programming Reference.*)
Font metrics have been added to the &xwp; font sample view to allow
you to find out whether maybe a font file is broken. In addition, this might
help programmers to find out what all the misnamed fields in &os2;'s
FONTMETRICS
structure really represent.
You can select the metrics to be displayed from an open sample view's &popmenu;.
If you find all this confusing, simply disable all font metrics display
and never use it again.
Otherwise see "Font metrics" for details.
