GetOutlineTextMetrics
The GetOutlineTextMetrics
function retrieves text metrics for TrueType fonts.
UINT GetOutlineTextMetrics(
|
HDC hdc, |
// handle of device
context |
|
UINT cbData, |
// size of metric
data array |
|
LPOUTLINETEXTMETRIC lpOTM |
// address of
metric data array |
|
); |
|
Parameters
hdc
Identifies
the device context.
cbData
Specifies the
size, in bytes, of the array in which the text metrics are to be returned.
lpOTM
Points 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 TRUE or the size of the required buffer.
If the
function fails, the return value is FALSE. 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.
