3: GetOutlineTextMetrics

Summary

The GetOutlineTextMetrics API

static extern uint GetOutlineTextMetrics(IntPtr hdc, uint cbData, IntPtr ptrZero);

OUTLINETEXTMETRIC

Since otmpFamilyName, otmpFaceName, otmpStyleName, otmpFullName are actually offsets into the structure from the beginning of the structure you need double call GetOutlineTextMetrics.

Warning

The OUTLINETEXTMETRIC structure includes a TEXTMETRIC structure which includes some TCHAR fields. A TCHAR can compile to a 16 bit character or a 8 bit character (depending on whether UNICODE is defined). The C# version of the TEXTMETRIC structure on PInvoke.net assumes that the TCHAR is a 16 bit character and when you retrieve a TEXTMETRIC structure with GetTextMetrics you do get a TEXTMETRIC structure with 16 bit characters. However, when you retrive an OUTLINETEXTMETRIC structure with GetOutlineTextMetrics the included TEXTMETRIC structure appears to have 8 bit characters. (These observations were with Windows XP and might not hold true for other operating systems or all fonts.)

uint cbBuffer = GetOutlineTextMetrics(hdc, 0, IntPtr.Zero);

if (GetOutlineTextMetrics(hdc, cbBuffer, buffer) != 0)

OUTLINETEXTMETRIC otm = new OUTLINETEXTMETRIC();

otm = (OUTLINETEXTMETRIC)Marshal.PtrToStructure(buffer, typeof(OUTLINETEXTMETRIC));

4: GetTextMetrics

Summary

The GetTextMetrics API

static extern bool GetTextMetrics(IntPtr hdc, out TEXTMETRIC lptm);

private static extern bool GetTextMetricsW(IntPtr hdc, out TEXTMETRICW lptm);

private static extern bool GetTextMetricsA(IntPtr hdc, out TEXTMETRICA lptm);

TEXTMETRIC

It's very important to use the same charset on the TEXTMETRIC structure and the extern function.

public static TEXTMETRIC GetTextMetrics(Graphics graphics, Font font)

TEXTMETRIC textMetric;

bool result = GetTextMetrics(hDC, out textMetric);

return textMetric;

static extern bool GetTextMetrics(IntPtr hdc, out TEXTMETRIC lptm);

internal struct TEXTMETRIC

public ref struct TEXTMETRIC

static bool GetTextMetrics(IntPtr hdc, [Out] TEXTMETRIC% lptm);

TEXTMETRIC^ GetTextMetricsReal(Graphics^ g, Font^ font)

TEXTMETRIC^ textMetric = gcnew TEXTMETRIC;

bool result = Win32::GetTextMetrics(hDC, *textMetric);

return textMetric;

Remarks

Always be explicit which character set you want to use. Use either TEXTMETRICA with the character set Ansi or TEXTMETRICW with the character set Unicode. Avoid the use of Auto as it is platform dependent and might cause memory leaks.
