What about

HDC Win32_IC()
{
	static HDC hdc;
	ONCELOCK {
		hdc = CreateDC("DISPLAY", NULL, NULL, NULL);
	}
	return hdc;
}


Bad/missing letters were found.

Well, failing VERIFY is interesting. Let us dig a bit more there...

void RenderCharacterSys(FontGlyphConsumer& sw, double x, double y, int ch, Font fnt)
{
	DLOG("RenderCharSys " << fnt << " " << ch << " " << (char)ch);
	static Atomic h;
	h++;
	HFONT hfont = GetWin32Font(fnt, 0);
	VERIFY(hfont);
	if(hfont) {
		HDC hdc = Win32_IC();
		HFONT ohfont = (HFONT) ::SelectObject(hdc, hfont);
		GLYPHMETRICS gm;
		MAT2 m_matrix;
		memset(&m_matrix, 0, sizeof(m_matrix));
		m_matrix.eM11.value = 1;
		m_matrix.eM22.value = 1;
		int gsz = GetGlyphOutlineW(hdc, ch, GGO_NATIVE|GGO_UNHINTED, &gm, 0, NULL, &m_matrix);
		VERIFY(gsz >= 0);
		if(gsz < 0)
			return;
		StringBuffer gb(gsz);
		gsz = GetGlyphOutlineW(hdc, ch, GGO_NATIVE|GGO_UNHINTED, &gm, gsz, ~gb, &m_matrix);
		VERIFY(gsz >= 0);
		if(gsz < 0)
			return;
		RenderCharPath(~gb, gsz, sw, x, y + fnt.GetAscent());
		::SelectObject(hdc, ohfont);
	}
	h--;
	VERIFY(h == 0);
}


If it fails, send me where and the log....

(Please note, it was VERIFY(h == 0), i.e. your original ASSERT... not VERIFY(hfont).)

Yes, I will test... using RLOG() instead of DLOG().

VERIFY failed on the first VERIFY(gsz >= 0); on line 415.

Now I even managed to include the log attachment! Smile

Well, so be it, lets call it a fix. I will remove shared information context from the trunk... There will be small performance penalty, but it should be negligible (as there are caches on many levels anyway).

Hopefully my interpretation is right and we are not just hiding some other bug...

As far as I can see, not a single bad or missing letter in 8 minutes of systematic intensive scanning of names. No VERIFYs/ASSERTs either. The log is attached.

Well, so be it, lets call it a fix. I will remove shared information context from the trunk... There will be small performance penalty, but it should be negligible (as there are caches on many levels anyway).

Hopefully my interpretation is right and we are not just hiding some other bug...


OK, I hope so too. Using Windows can be expensive sometimes...

As for the 'rounding of tolerance' we discussed about one hundred (or so) postings ago, should it be brought in rather sooner or later? I would like to test this current solution without other changes for a while before taking in an optimization that will decrease likelihood for error. (Actually, I believe this will solve it for good, but it's better keep an eye on it for a while... This does not 'add to cost' as I will anyway look at the map during testing of new features I'm building on top of this.)

Of course I can take this fix in now, and then postpone updating the tolerance rounding, until a week or so have passed...

In any case, Thank you Mirek for all your help and support!

Best regards,

Tom

I will deal with tolerance after we are sure that the issue is fixed (otherwise it would hide that bug).

It will be actually pretty simple, what I plan to do is this:

		tolerance = float(0.3 / attr.mtx.GetScale());

OK, that's simple, clear and does not eat many CPU cycles! Smile
