ctypes data-pointers as a data-format mechanism

Classes

class CtypesPointerHandler( FormatHandler ):
Ctypes Pointer-type-specific data-type handler for OpenGL
Because pointers do not have size information we can't use them for output of data, but they can be used for certain types of input...
arraySize( self , value , typeCode = None )
Given a data-value, calculate dimensions for the array
arrayToGLType( self , value )
Given a value, guess OpenGL type of the corresponding pointer
asArray( self , value , typeCode = None )
Convert given value to an array value of given typeCode
dataPointer( )
addressof(C instance) -> integer Return the address of the C instance internal buffer
dimensions( self , value , typeCode = None )
Determine dimensions of the passed array value (if possible)
from_param( cls , value , typeCode = None )
ones( self , dims , typeCode = 'd' )
Return numpy array of ones in given size
unitSize( self , 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( self , dims , typeCode )
Return Numpy array of zeros in given size
