GetOutlineTextMetrics

The GetOutlineTextMetrics function retrieves text metrics for TrueType fonts.

UINT GetOutlineTextMetrics(
  HDC hdc,                    // handle to device context
  UINT cbData,                // size of metric data array
  LPOUTLINETEXTMETRIC lpOTM   // pointer to metric data array
);
 

Parameters

hdc

Handle to the device context.

cbData

Specifies the size, in bytes, of the array in which the text metrics are to be returned.

lpOTM

Pointer to an array of OUTLINETEXTMETRIC structures. If this parameter is NULL, the function returns the size of the buffer required for the retrieved metric data.

Return Values

If the function succeeds, the return value is nonzero or the size of the required buffer.

If the function fails, the return value is zero.

Windows NT: To get extended error information, call GetLastError.

Remarks

The OUTLINETEXTMETRIC structure contains most of the text metric information provided for TrueType fonts (including a TEXTMETRIC structure). The sizes returned in the OUTLINETEXTMETRIC structures are in logical units; they depend on the current mapping mode.
