New commits: commit 0686abc10aa729c8768b06249dbf7e57f4e56ae5 Author: Tomaž Vajngerl <[email protected]> Date: Thu Jul 13 13:30:20 2017 +0200 tdf#107166 BindDC doesn't handle 0 width/height rect consistently When binding a GDI device context to D2D we need to provide a rectangle where the surface will have effect. When we just need some font information we need to bind the DC too, but we aren't really interested what the rectangle is, so we just provided a 0,0,0,0 rectangle in that case. This sometimes fails with a "out of memory" result and is dependent on the renderer. Instead of 0,0,0,0 rectangle we rather define a 0,0,1,1 rectangle which should never fail. This is not problematic as for actual rendering we later rebind with an actual rectangle.
