### GpiQueryFontmetrics

GpiQueryFontMetrics is an OS/2 API call that is used to query the current printer and display drivers for the font metrics (measurements) that would be used when printing or displaying the current font. Select this menu item to query the currently realized font metrics information of the file.

These font metrics represent any changes made to the font from the Font page of the Program Settings notebook

The Font Metrics displayed in the Font page are really displaying designer units. Designer units are the height and width values for a font if it is realized at its nominal point size. Outline fonts can be realized at any point size between their minimum and maximum point sizes, and their heights and widths are scaled accordingly.
