+    mf = CreateEnhMetaFileA( GetDC( 0 ), NULL, NULL, NULL );
+    ok( mf != 0, "CreateEnhMetaFileA error %d\n", GetLastError() );
+
+    SetMapMode(mf, MM_ANISOTROPIC);
+    SetViewportExtEx(mf, 1, -1, &size);
+
+    /* A EMR_SETARCDIRECTION record is inserted here. */
+
+    ret = Arc(mf, 342, -215, 442, -315, 342, -265, 442, -265);
+    ok( ret, "Arc failed error %d\n", GetLastError() );

What happens if you don't call SetMapMode and/or SetViewportExtEx?
