Computer Graphics Bundled Attributes

3.  When each function reference a
single attributes that specify exactly
how primitives to be displayed.
 It is called individual (unbundled
attributes).

4.  Bundled attributes is where a set
of attributes value can be chosen
by specifying the appropriate
index table.
 The table for each primitive that
defines group of attribute value
is called bundled table.

6.  Bundled line attributes
 Bundled area fill attributes
 Bundled text attributes
 Bundled marker attributes

7.  Entries in the bundle
table for line attributes on
a specified workstation
are set with function
 SetpolylineRepresentatio
n(ws, li, lt, lw, lc)

8.  Parameter ws is the workstation
identifier, and line li defines the
position.
 Parameter lt, lw, lc are then
bundled and assigned values to
set the line type, line width and
line color for the designated table
index.

10. Setpolylinerepresentation(1,
3,2,0.5,1) ;
SetpolylineRepresentation (4,
3,2,1,7) ;
A polyline that is aasigned a
table index value of 3 would
then be displayed .

12.  Table entries for bundled area fill
attributes are set with
SetInteriorRepresentation(ws, fi, fs, pi,
fc)
 It defines the attribute list
corresponding to fill index fi on
workstation ws.

 Parameters fs, pi, fc are assigned values
for the fill style, patter index and fill
color.

13.  The function
 SetTextRepresentation(ws, to, tf,
to, te, ts, tc)

14.  Bundled values for text font,
precision, expansion factor, size
and color in a table position for
workstation ws that is specified
by the value assigned to text
index parameter to.

16.  Table entries for bundled marker
attributes are set up with
SetPolymarkerRepresentation(ws, mi,
mt, ms, mc)
 This defines the marker type, marker
scale factor and marker color for index
mi on workstation ws.
 Bundle table selection are then made
with the function
SetPolymarkerIndex(mi)

18.  Current settings for attributes
and other parameters, such as
workstation types and status, in
the system lists can be retrieved
with inquiry function.
 Copy the current values for line
index and fill color into lastli and
lastfc.

19. inquirePolylineIndex(lastli) inquireInteriorColorIndex(lastfc)

20.  Copy the current values for line
index and fill color into lastli and
lastfc.
