  • aWorldBounds (GM_Rectangle_t) – World bounds to convert from or None for last drawn

  • aPixelRect (GM_PixelRect_t) – Pixel bounds to convert from or None for last drawn

  • aForExport (bool) – Get zoom scale for an export (TRUE) or draw (FALSE)

  • aExtraOpts (str) – str with extra options, like RES_MULT

  • aReserved (uint32) – Reserved for future use; defaults to 0
