Summary: GDI32 painting.c, AngleArc function renders improperly Product: Wine Version: 0.9.30. Platform: PC OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: wine-misc AssignedTo: wine-bugs@winehq.org ReportedBy: ninevoltz@metalink.net
The AngleArc function of GDI32 does not render arcs properly. I'm guessing that this is possibly because M_PI is a defined as a double and the parameters to the routine are floats. See my attached program, angle.exe. You can prove the bug with it. Set Wine to Windows 2000/XP before running it.
