XkwView2DatasetsRegisterDataset (Widget W,
iarray pseudo, double min, double max,
iarray red, iarray green, iarray blue,
unsigned int set_number)
Register a dataset.
Parameters:
- W :
The widget.
- pseudo :
The PseudoColour dataset (i.e. single-channel). This may be NULL.
- min :
The minimum value in the PseudoColour dataset.
- max :
The maximum value in the PseudoColour dataset.
- red :
The red component dataset. This may be NULL.
- green :
The green component dataset. This may be NULL.
- blue :
The blue component dataset. This may be NULL.
- set_number :
The dataset number. This may be 0 or 1.
Returns: TRUE on success, else FALSE.

EXPERIMENTAL FUNCTION: subject to change without notice
void
XkwView2DatasetsInvalidatePlane (Widget W, unsigned int set_number,
unsigned int dim_index,
unsigned long plane_index)
Register the change in data of a plane.
Parameters:
- W :
The widget.
- set_number :
The dataset number. This may be 0 or 1.
- dim_index :
The dimension index of the plane.
- plane_index :
The index along the specified dimension.
Returns: Nothing.
Multithreading Level: Unsafe
EXPERIMENTAL FUNCTION: subject to change without notice
void
XkwView2DatasetsInvalidateAll (Widget W, unsigned int set_number)
Register the change in data of a dataset.
Parameters:
- W :
The widget.
- set_number :
The dataset number. This may be 0 or 1.
Returns: Nothing.
Multithreading Level: Unsafe

XkwView2DatasetsCanvasEventHandler (ViewableImage vimage,
double x, double y,
void *value, unsigned int event_code,
void *e_info, void **f_info,
double x_lin, double y_lin,
unsigned int value_type,
double x_im, double y_im,
int x_pix, int y_pix)
This routine is a position event consumer for a world canvas
which has a number of ViewableImage objects associated with it.
Parameters:
- viewimg :
The active viewable image.
- x :
The horizontal world co-ordinate of the event.
- y :
The vertical world co-ordinate of the event.
These values will have been transformed by the registered transform
function (see canvas_register_transform_func ) for the associated
world canvas.
- value :
A pointer to the data value in the viewable image corresponding
to the event co-ordinates.
- event_code :
The arbitrary event code.
- e_info :
The arbitrary event information.
- f_info :
The arbitrary function information pointer.
- x_lin :
The linear horizontal world co-ordinate (the co-ordinate prior
to the transform function being called).
- y_lin :
The linear vertical world co-ordinate (the co-ordinate prior
to the transform function being called).
- value_type :
The type of the data value. This may be K_DCOMPLEX or
- x_im :
The horizontal image pixel co-ordinate. 0.0 is the pixel centre.
- y_im :
The vertical image pixel co-ordinate. 0.0 is the pixel centre.
- x_pix :
The horizontal screen pixel co-ordinate.
- y_pix :
The vertical screen pixel co-ordinate.
K_UB_RGB.
Returns: FALSE indicating that the event is still to be processed.
