Changing DWriteMeasuringMode for DrawTextLayout

Question

I am currently drawing text in DirectWrite using DrawText.

On my switch to DrawTextLayout i noticed that the rendering of aliased letters isn't done nicely.

Is there a way to change the measurement mode like we can do in DrawText to DWRITE_MEASURING_MODE_GDI_CLASSIC

Top text is drawn with DrawText (and DWRITE_MEASURING_MODE_GDI_CLASSIC), bottom with DrawTextLayout.

As you can see the character spacing isn't nice in the bottom text.

If i set the measuring mode of DrawText to DWRITE_MEASURING_MODE_NATURAL i have the exact same result like drawing with TextLayout. So the problem is the measuring mode which i don't know how to change.

Answer 1

Got it working.

I totally didn't see that function:

DWriteFactory.CreateGdiCompatibleTextLayout

However when using Delphi they messed up the params as stated here:

For whatever reason they refure to fix that as it was reported in 2013:
