Bool isImported

Check if the API is or can be imported.

PySys_GetObject uses char* instead of const char*, so use a cast.

makeArray()

ValueHolder makeArray	(	PyObject *	obj_ptr,
		Bool	copyData
	)

Convert the python array to a Casacore array in the ValueHolder.

If copyData is True, the array data is always copied. Otherwise only if needed.

incr refcount, because ~object decrements it

Swap axes, because Casacore has row minor and Python row major order. A scalar is treated as a vector with length 1.

Assert array is contiguous now. If the array is empty, numarray still sees it as non-contiguous.

&& PyArray_ISALIGNED(po) fails on MIPS (see issue 531)

Create the correct array.

Some types can be the same as other types, so they cannot be used in the switch (compiler complains). This is true for BYTE and SBYTE which can equal to BOOL in numarray. Similarly for STRING which exists for numpy and is set to INT for numarray.

Copy using signed char, because uChar is mapped to Short in the Traits.

Convert a Casacore array to a Python array object.

PycArrayCheck()
