- globalmapper.ConvertCoordPixelToGroundWithOrientationDouble(float aPixelX, float aPixelY, GM_Rectangle_t aWorldBounds, GM_PixelRect_t aPixelRect, float aOrientation) GM_Error_t32, float, float
-
Convert a coordinate between pixel space and the current projection. The conversion space can be either the last drawn coordinate space or the caller can provide the coordinate space to work in. You also need to supply an orientation (rotation angle) at which to do the conversion.
Note that the input pixel coordinates are floats. If you want to use sint32’s instead, use the function ConvertCoordPixelToGroundWithOrientation.
Note: The only time that you should need to call this function is if you want to do a coordinate conversion in a different orientation than what has been set globally with SetOrientation.
- Parameters:
-
aPixelX (float) – X Coord in pixel space
aPixelY (float) – Y Coord in pixel space
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
aOrientation (float) – Orientation of coordinate space to use (0 is north up, 90 is east up, 180 is south up, 270 is west up)
