Constants
Defined Argument Constant Description
---------------------------------------------------------------------------
DM PCDM Digital PHIGS uses any colors specified
with the output primitive as the source
of color.
PSUDM Digital PHIGS maps a single data value to
a color selected from a specified list of
colors. Digital PHIGS selects the color
based on the relationship of the data
value to a specified data range.
PSNUDM Digital PHIGS maps a single data value to
a color selected from a specified list of
colors. Digital PHIGS selects the color
based on the relationship of the data
value to a specified set of data ranges.
PBUDM Digital PHIGS maps two data values to a
single color selected from one of a set
of color lists. The first value
specifies the list to use, and the second
value specifies which color to select
from that list.
PBNUDM Digital PHIGS maps two data values to a
single color selected from one of a set
of color lists. Digital PHIGS selects the
color based on the relationships of the
data values to a specified set of data
ranges.

Description
PQPDMR queries the workstation description table and returns the data mapping type and data mapping information for the specified index.
Digital PHIGS Version 3.1 does not support this function.
Data Record Information
If DMM is PCDM, the data record has the following format:
INTEGER IL = 1+∗ Number of integer elements
INTEGER IA(1) Number of source selectors (NSS)
INTEGER IA Elements 2 through NSS+1 contain source selectors
RL = 0
RA = ()
SL = 0
LSTR = ()
STR = ()
If DMM is PSUDM, the data record has the following format:
INTEGER IL = 5+∗ Number of integer elements
INTEGER IA(1) Number of source selectors (NSS)
INTEGER IA Elements 2 through NSS+1 contain source selectors
INTEGER IA(NSS+2) = Data value index
INTEGER IA(NSS+3) = Color type
INTEGER IA(NSS+4) = Number of specified color (NCV)
INTEGER RL = 2+∗ Number of real elements
REAL RA(1) = Lower range limit
REAL RA(2) = Upper range limit
SL = 0
LSTR = ()
STR = ()
If the color type is PINDIR:
IA = Elements NSS+5 through NSS+4+NCV contain the color
indexes
If the color type is PRGB, PCIE, PHSV, or PHLS:
IA(NSS+5) = Number of color value components (NCC)

values (for example, r1, g1, b1, r2, g2,
b2,
...
)

INTEGER IA(NSS+3) = Color type
INTEGER IA(NSS+4) = Number of range boundaries, or the number of the
specified color - 1 (NRB)
INTEGER RL = NRB+∗ Number of real elements
REAL RA = Elements 1 through NRB contain the range boundary
SL = 0
LSTR = ()
STR = ()
If the color type is PINDIR:
IA = Elements NSS+5 through NSS+4+NRB+1 contain the color
indexes
If the color type is PRGB, PCIE, PHSV, or PHLS:
