^'GetTextExtentPoint Note
|
|
|
366 |
|
|
|
367 |
The GetTextExtentPoint function computes the width and height of the specified string of text.
|
|
|
368 |
|
|
|
369 |
Note This function is provided only for compatibility with 16-bit versions of Windows. Applications should call the GetTextExtentPoint32 function, which provides more accurate results.
|
|
|
370 |
|
|
|
371 |
BOOL GetTextExtentPoint(
|
|
|
372 |
HDC hdc, // handle to DC
|
|
|
373 |
LPCTSTR lpString, // text string
|
|
|
374 |
int cbString, // number of characters in string
|

Parameters
|
|
|
379 |
|
|
|
380 |
hdc
|
|
|
381 |
[in] Handle to the device context.
|
|
|
382 |
lpString
|
|
|
383 |
[in] Pointer to the string that specifies the text. The string does not need to be zero-terminated, since cbString specifies the length of the string.
|
|
|
384 |
cbString
|
|
|
385 |
[in] Specifies the length of the string pointed to by lpString.
|
|
|
386 |
|
|
|
387 |
Windows 95/98/Me: This value may not exceed 8192.
|
|
|
388 |
lpSize
|
|
|
389 |
[out] Pointer to a SIZE structure that receives the dimensions of the string, in logical units.
|
|
|
390 |
|
|
|
391 |
Return Values
|
|
|
392 |
|
|
|
393 |
If the function succeeds, the return value is nonzero.
|
|
|
394 |
|
|
|
395 |
If the function fails, the return value is zero.
|
|
|
396 |
|
|
|
397 |
Windows NT/2000/XP: To get extended error information, call GetLastError.
|
|
|
398 |
Remarks
|
|
|
399 |
|
|
|
400 |
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. Also, this function assumes that the text is horizontal, that is, that the escapement is always 0. This is true for both the horizontal and vertical measurements of the text. Even if using a font specifying a nonzero escapement, this function will not use the angle while computing the text extentthe application must convert it explicitly.
|
|
|
401 |
|
|
|
402 |
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.
|
|
|
403 |
|
|
|
404 |
The calculated string width takes into account the intercharacter spacing set by the SetTextCharacterExtra function.
|
|
|
405 |
|
|
|
406 |
Windows 95/98/Me: For compatibility with Windows 3.1, GetTextExtentPoint adds an extra pixel for bold simulation fonts. However, the bold Tahoma font is not simulated, so it does not have any extra pixel. To correct for the extra pixel in a bold simulation font, decrease the length of every substring passed to GetTextExtentPoint by one pixel and add an extra pixel for the entire string.
|
|
|
407 |
|
|
|
408 |
Windows 95/98/Me: Although GetTextExtentPointW exists on Windows 95/98/Me, it is supported by the Microsoft Layer for Unicode to give more consistent behavior across all Windows operating systems. To use this, you must add certain files to your application, as outlined in Microsoft Layer for Unicode on Windows 95/98/Me Systems.
