     NAME
          XmeFromHorizontalPixels - Converts from pixels to real-world
          dimensions based on horizontal resolution of the screen

     SYNOPSIS
          #include <Xm/XmP.h>
          void XmeFromHorizontalPixels(
          Widget widget,
          int offset,
          XtArgVal *value);

     VERSION
          This page documents Motif 2.1.

     DESCRIPTION
          XmeFromHorizontalPixels converts a horizontal pixel value to
          a real-world dimensional unit. The real-world dimensional
          unit depends on the value of the XmNunitType resource
          associated with the widget.  For example, suppose widget has
          an XmNunitType resource value of Xm1000THINCHES. If the
          input value were 200 pixels, the output value might be 2500
          (2.5 inches) on one screen and 2000 (2.0 inches) on another
          screen.

          XmeFromHorizontalPixels is an XmExportProc.

          Typically, your widgets will call this function in a
          synthetic resource record.

          widget    Specifies the widget.

          offset    Specifies the offset (in bytes) of a synthetic
                    resource field in the widget record.

          value     Specifies a value in pixels and returns a value in
                    the dimensional units used by widget.
