Macro Definition Documentation

◆ import_pyprojection

#define import_pyprojection ( )

Value:

PyProjection_API = (void **)PyCapsule_Import(PyProjection_CAPSULE_NAME, 1);

Imports the pyprojection module (like import _projection in python).

◆ PyProjection_API_pointers

#define PyProjection_API_pointers 4

number of function and variable pointers

◆ PyProjection_Check

#define PyProjection_Check ( op )

Value:

(Py_TYPE(op) == &PyProjection_Type)

Checks if the object is a python projection.

◆ PyProjection_GetNative

#define PyProjection_GetNative (*(PyProjection_GetNative_RETURN (*)PyProjection_GetNative_PROTO) PyProjection_API[PyProjection_GetNative_NUM])

Returns a pointer to the internal projection, remember to release the reference when done with the object.

(RAVE_OBJECT_RELEASE).

◆ PyProjection_GetNative_NUM

#define PyProjection_GetNative_NUM 1

index for GetNative

◆ PyProjection_GetNative_PROTO

#define PyProjection_GetNative_PROTO (PyProjection*)

argument prototype for GetNative

◆ PyProjection_GetNative_RETURN

#define PyProjection_GetNative_RETURN Projection_t*

return type for GetNative

◆ PyProjection_New

#define PyProjection_New (*(PyProjection_New_RETURN (*)PyProjection_New_PROTO) PyProjection_API[PyProjection_New_NUM])

Creates a new projection instance.

Release this object with Py_DECREF. If the passed Projection_t instance is bound to a python instance, this instance will be increfed and returned.

Parameters

[in] proj - the Projection_t intance.

Returns: the PyProjection instance.

◆ PyProjection_New_NUM

#define PyProjection_New_NUM 2

index for New

◆ PyProjection_New_PROTO

#define PyProjection_New_PROTO (Projection_t*)

argument prototype for New

◆ PyProjection_New_RETURN

#define PyProjection_New_RETURN PyProjection*

return type for New

◆ PyProjection_NewFromDef

#define PyProjection_NewFromDef (*(PyProjection_NewFromDef_RETURN (*)PyProjection_NewFromDef_PROTO) PyProjection_API[PyProjection_NewFromDef_NUM])

Creates a new projection instance from a definition.

Release this object with Py_DECREF.

Parameters

[in]	id	- the id for this projection
[in]	description	- the description of this projection
[in]	definition	- the proj.4 definition

Returns: the PyProjection instance.

◆ PyProjection_NewFromDef_NUM

#define PyProjection_NewFromDef_NUM 3

index for NewFromDef

◆ PyProjection_NewFromDef_PROTO

#define PyProjection_NewFromDef_PROTO (const char* id, const char* definition, const char* description)

argument prototype for NewFromDef

◆ PyProjection_NewFromDef_RETURN

#define PyProjection_NewFromDef_RETURN PyProjection*

return type for NewFromDef

◆ PyProjection_Type_NUM

#define PyProjection_Type_NUM 0

index for Type
