-
Determine the zoom scale that will be used to draw/export from a provided tiled online layer for a given bounds.
- Parameters:
-
aLayer (GM_LayerHandle_t32) – Tiled online layer to query
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
- Returns:
-
Error Code
- Return type:
-
GM_Error_t32
- Returns:
