Syntax
BOOL GetTextExtentPoint( HDC hdc, LPCTSTR lpString, int cbString,
LPSIZE lpSize);
Parameters
hdc
[in] Handle to the device context (DC).
lpString
[in] Long pointer to the string of text. The string does not need to be zero-terminated, since cbString specifies the length of the string.
cbString
[in] Specifies the number of characters in the string.
lpSize
[out] Long pointer to a SIZE structure in which the dimensions of the string are to be returned.
Return Values
Nonzero indicates success. Zero indicates failure. To get extended error information, call GetLastError.
Remarks
The GetTextExtentPoint 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.
The GetTextExtentPoint function is identical to the GetTextExtentPoint32 function.
