allocateiAImage()

iAbase_API vtkSmartPointer< iAvtkImageData > allocateiAImage	(	int	vtkType,
		int const	dimensions[3],
		double const	spacing[3],
		int	numComponents )

allocate an iAvtkImageData image

clearImage()

template<typename T >

void clearImage	(	vtkImageData *	img,
		T	c )

Set all pixels in the given image to the given value See the notes for drawPixel regarding Modified().

WARNING: Only tested for INT type at the moment!

drawLine()

template<typename T >

void drawLine	(	vtkImageData *	img,
		int	x1,
		int	y1,
		int	x2,
		int	y2,
		T	c )

Draw a line in the given image.

See the notes for drawPixel regarding Modified(). WARNING: Only tested for INT type at the moment!

drawPixel()

template<typename T >

void drawPixel	(	vtkImageData *	img,
		int	x,
		int	y,
		int	z,
		T	c )

Change a single pixel in the given image.

Don't forget to call Modified() on the image, and if the scalar range changed, to update the scalar range (unfortunately that seems to require a "dirty hack" at the moment, see iAvtkImageData above). WARNING: Only tested for INT type at the moment!
