DESCRIPTION
XmtLayoutConvertSizeToPixels() converts a floating point value measured in millimeters, inches, printer points, ems, or ens to an integral number of pixels and returns that number. Conversion to millimeters, inches or points depends on the resolution of the screen of w. Conversion to ems and ens depends on the XmtNfont and XmtNfontList resources of w. An ``em'' is the width of the letter ``M'' in the specified font or in the default font of the font list. An ``en'' is one half of one em.SEE ALSO
