GetTextExtentPoint32
The GetTextExtentPoint32 function computes the width and height of the specified string of text. This
function supersedes the GetTextExtentPoint function.
BOOL GetTextExtentPoint32(
HDC hdc,
| // handle of device context
| LPCTSTR lpString,
| // address of text string
| int cbString,
| // number of characters in string
| LPSIZE lpSize
| // address of structure for string size
| );
|
|
Parameters
hdc
Identifies the device context.
lpString
Points to the string of text. The string does not need to be zero-terminated,
since cbString specifies the length of the string.
cbString
Specifies the number of characters in the string.
lpSize
Points to a SIZE structure in which the dimensions of the string are to be returned.
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error
information, call GetLastError.
Remarks
The GetTextExtentPoint32 function uses the currently selected font to compute the dimensions of the
string. The width and height, in logical units, are computed without considering
any clipping.
Because some devices kern characters, the sum of the extents of the characters
in a string may not be equal to the extent of the string.
The calculated string width takes into account the intercharacter spacing set
by the SetTextCharacterExtra function.
