NAME
       XmtLayoutConvertSizeToPixels()  - convert a resolution independent size
       to pixels.

SYNOPSIS
       #include	<Xmt/Layout.h>

       int XmtLayoutConvertSizeToPixels(Widget w, double size,
		      XmtLayoutUnitType	units)

       typedef enum { XmtLayoutPoints, /* 1/72 of an inch */ XmtLayoutInches,
		      /* 25.4 millimeters */ XmtLayoutMillimeters, /* depends
		      on display resolution */ XmtLayoutEms, /*	width of `M'
		      in widget	font */	XmtLayoutEns, /* 1/2 of	an em */
       } XmtLayoutUnitType;

ARGUMENTS
       INPUTS

	    w	   An XmtLayout	widget.

	    size   The size to be converted.

	    units  The units that size is measured in.

       RETURNS

	    The	pixel equivalent of the	size measured in units.

DESCRIPTION
       XmtLayoutConvertSizeToPixels() converts a floating point	value measured
       in millimeters, inches, printer points, ems, or ens to an integral num-
       ber of pixels and returns  that	number.	  Conversion  to  millimeters,
       inches  or points depends on the	resolution of the screen of w. Conver-
       sion 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.
