CDC::GetOutputTextExtent

  • 项目

CSizeGetOutputTextExtent(LPCTSTRlpszString**,intnCount)const;**

CSize GetOutputTextExtent( const CString& str ) const;

Return Value

The dimensions of the string (in logical units) returned in a CSize object.

Parameters

lpszString

Points to a string of characters. You can also pass a CString object for this parameter.

nCount

Specifies the number of characters in the string. If nCount is –1, the length is calculated.

str

 A CString object that contains the specified characters to be measured.

Remarks

Call this member function to use the output device context, m_hDC, and compute the width and height of a line of text, using the current font.

The current clipping region does not affect the width and height returned by GetOutputTextExtent.

Since some devices do not place characters in regular cell arrays (that is, they carry out kerning), the sum of the extents of the characters in a string may not be equal to the extent of the string.
