# IFont::SetRatio

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

HRESULT SetRatio(

long cyLogical , | //Font size in logical units
long cyHimetric | //Font size in HIMETRIC units
); |

Parameters

cyLogical
  [in] Font size in logical units.
cyHimetric
  [in] Font size in HIMETRIC units.

Return Values

The method supports the standard return values E_UNEXPECTED and E_INVALIDARG, as well as the following:

S_OK
  The ratio was set successfully.
