Mapping modes during metafile playback - need documentation!
When I am playing back an enhanced metafile using EnumEnhMetaFile(), it appears that the coordinate system functions (GetWindowOrg, GetViewportExt, etc.) all return invalid values. For example, if the metafile says SetMapMode(MM_ISOTROPIC) SetViewportOrg(50, 50) and inside my EnhMetaFileProc (which is simply cal... 19 Mar 2010 09:17
