pe_coordsys_to_string_ext |
Creates an extended string representation of a coordsys object
void pe_coordsys_to_string_ext (PE_COORDSYS coordsys, int mode, char buffer[PE_BUFFER_MAX]);
coordsys | A horizontal coordinate system object |
mode | The mode of the string representation |
buffer | The string representation of the object |
This function creates an extended string representation of a coordinate system object.
The values for the mode parameter are:
PE_STR_AUTH_NONE 0 /* No authority information */ PE_STR_AUTH_TOP 1 /* Only include authority information for the top-level object */ PE_STR_AUTH_ALL 2 /* Include authority information for all objects */
In pe_coordsys_to_string_ext, the coordinate system is considered the top-level object. Thus, any subobjects, such as the DATUM and SPHEROID in a geographic coordinate system, would not include authority information if the mode is set to PE_STR_AUTH_TOP.
None
Mode is set to PE_STR_AUTH_ALL:
