C --*** GRSNAP *** (GRPLIB) Perform movie snap operations

C --
|

|
C --GRSNAP sets up a device for snapping multiple frames for movies.
|
||
|
|
C --This code is very device-dependent.
|
||
|
|
C --
|
||
|
|
C --At the present time, the only device that may be snapped is a camera
|
||
|
|
C --(attached to a terminal) or a Dicomed.
|
||
|
|
C --
|
||
|
|
C --An attached camera device must be pre-initialized and NSNAP must
|
||
|
|
C --be set non-negative (zero ok).

C --

|
C --Parameters:
|
||
|
|
C -- CMD - IN - the snap operation:
|
||
|
|
C -- QUERY = initialize device code, nsnap < 0 if cannot snap frames
|
||
|
|
C -- INIT = initialize device to snap nsnap frames
|
||
|
|
C -- ABORT = abort plot
|
||
|
|
C -- START = start plot
|
||
|
|
C -- STOP = end plot and snap frames
|
||
|
|
C -- EXIT = deactivate device
|
||
|
|
C -- INDEV - IN - the device; 0 for current device (only QUERY allowed

C -- for non-current device)
