IFont::SetRatio method (ocidl.h)
Converts the scaling factor for this font between logical units and HIMETRIC units. HIMETRIC units are used to express the point size in the IFont::get_Size and IFont::put_Size methods. The values passed to IFont::SetRatio are used to compute the display size of the font in logical units from the value in the Size property:
Display Size = ( cyLogical / cyHimetric ) * Size
Syntax

[in] LONG cyLogical,
[in] LONG cyHimetric
);
Parameters
[in] cyLogical
The font size, in logical units.
[in] cyHimetric
