Hi, is there a way to read back the coordinates of a PathGeometry? That would make sense after having done modifications on the geometry, e.g. Simplify, Combine or something. I read about it somewhere in a blog but no sample is given. One hint I read was to use DirectWrite for it. Any ideas? Thanks. Thomas

Wow! It works now. Thank you for your tip! Drawing the mesh is a lot faster than drawing the geometry. But where did you get these docs? I only found http://msdn.microsoft.com/en-us/library/dd371939(vs.85).aspx and there is no mentioning of antialiasing. And the CHM help file from the DX SDK only links to the MSDN libs. Thomas

Maybe it's a bug in the beta...

[quote user="Bjoern Graf"]But this sample fails, too? Otherwise the tesselation might be the problem, not this code.[/quote] Yes, I tried to simplify the case to 'get to the point' and it failed, too. A similar sequence worked with ...

Hi Bjoern, thanks for your reply. I think the sizeof() math is OK, it's the size of the whole array by the size of one element resulting in 1 (and teh debugger says so also). Anyway, that's just a test sample and I got the error first with a bunch of triangles tesselated from polygons. So there must be a problem in the rest of ...

Hi, my current tests reveal the following performance ranking in a MFC Direct2D MFC test app: 1) HwndRenderTarget (fastest) 2) drawing into a compatible BitmapRenderTarget and then blitting into a DCRenderTarget (ca. 30% slower) 3) drawing into a DCRenderTarget (much slower) Tests were run on a Q6600 machine with NV GF8800 GTS ...

Hi, in my Direct2D test app I'm getting HRESULT 0x88990001 from ID2D1RenderTarget::EndDraw() with zero tag1 and tag2. I can't find any docs for this error number. What I'm doing is: CRect rc; GetClientRect(rc); HRESULT hr = m_spDCRT->BindDC(pDC->GetSafeHdc(), &rc); ID2D1MeshPtr ...

Hi, do I ask Direct2D or DirectWrite questions in the Direct3D forum? Thanks, Thomas
