OpenGL.arrays.ctypesarrays

ctypes sized data-arrays as a data-formatmechanism

XXX we have to use _ctypes.Array as the type descriminator, would be nice to have it available from the public module

Classes

class CtypesArrayHandler( FormatHandler ):

Ctypes Array-type-specific data-type handler for OpenGL

arrayByteCount( cls , value , typeCode = None )

Given a data-value, calculate number of bytes required to represent

arraySize( cls , value , typeCode = None )

Given a data-value, calculate dimensions for the array

arrayToGLType( cls , value )

Given a value, guess OpenGL type of the corresponding pointer

asArray( cls , value , typeCode = None )

Convert given value to an array value of given typeCode

addressof(C instance) -> integer Return the address of the C instance internal buffer

dimensions( cls , value , typeCode = None )

Determine dimensions of the passed array value (if possible)

dims( cls , value )

Produce iterable of all dimensions

from_param( cls , value , typeCode = None )

ones( cls , dims , typeCode = 'd' )

Return numpy array of ones in given size

types( cls , value )

Produce iterable producing all composite types

unitSize( cls , value , typeCode = None )

Determine unit size of an array (if possible)

voidDataPointer( cls , value )

Given value in a known data-pointer type, return void_p for pointer

zeros( cls , dims , typeCode )

Return Numpy array of zeros in given size
