QDI(PARM)/DIP(ARM) - enquire and alter display parameters

QDIPARM prints what the current display parameters are. DIPARM alters them. Initially no scaling will be performed.

Parameters

QDIPARM requires none. For DIPARM :

option - 1, 2 or 3 for scaling options NONE (no scaling), FOLD (scale with wraparound) and TRUNCATE (scale with no wraparound) respectively

low - if option>1, data value to map to minimum intensity

high - if option>1, data value to map to maximum intensity

If omitted, all parameters are prompted for.

Examples

Adam:> DIPARM 1 scale = NONE

Notes

QDIPARM will print the current scaling values.

If the parameters are omitted, so a prompt is issued for option, the user response should be N, F or T, not 1, 2 or 3, and a response of "?" will show what the acceptable responses are. This comment is also true of the DATA, MODE, SMVAR and GMVAR commands.

For maximum information content, the FOLD scaling option is recommended.
