Function Documentation

int OPTGetParameterInfo ( const char *  pszProjectionMethod,
const char *  pszParameterName,
char **  ppszUserName,
char **  ppszType,
double *  pdfDefaultValue 
)

Fetch information about a single parameter of a projection method.

Parameters:
pszProjectionMethod name of projection method for which the parameter applies. Not currently used, but in the future this could affect defaults. This is the internal projection method name, such as "Tranverse_Mercator".
pszParameterName name of the parameter to fetch information about. This is the internal name such as "central_meridian" (SRS_PP_CENTRAL_MERIDIAN).
ppszUserName location at which to return the user visible name for the parameter. This pointer may be NULL to skip the user name. The returned name should not be modified or freed.
ppszType location at which to return the parameter type for the parameter. This pointer may be NULL to skip. The returned type should not be modified or freed. The type values are described above.
pdfDefaultValue location at which to put the default value for this parameter. The pointer may be NULL.
Returns:
TRUE if parameter found, or FALSE otherwise.

char** OPTGetParameterList ( const char *  pszProjectionMethod,
char **  ppszUserName 
)

Fetch the parameters for a given projection method.

Parameters:
pszProjectionMethod internal name of projection methods to fetch the parameters for, such as "Transverse_Mercator" (SRS_PT_TRANSVERSE_MERCATOR).
ppszUserName pointer in which to return a user visible name for the projection name. The returned string should not be modified or freed by the caller. Legal to pass in NULL if user name not required.
Returns:
returns a NULL terminated list of internal parameter names that should be freed by the caller when no longer needed. Returns NULL if projection method is unknown.

char** OPTGetProjectionMethods (  ) 

Fetch list of possible projection methods.

Returns:
Returns NULL terminated list of projection methods. This should be freed with CSLDestroy() when no longer needed.
