Module Description Files #!N #!EC #!N #!N The following examples illustrate 
the specification of three modules: Filter, Options, and ShowBox. #!N #!N 
The module description for Filter is: #!CForestGreen #!N #!N  #!F-adobe-courier-bold-r-normal--18*   #!N 
MODULE Filter #!N CATEGORY Transformation #!N DESCRIPTION applies a filter to 
a field #!N INPUT input; field; (none); data to filter #!N 
INPUT filter; value or string; "gaussian"; filter to use #!N INPUT 
component[visible:0]; string; "data"; component to be operated on #!N #!N OPTIONS 
data; colors #!N INPUT mask[visible:0]; value or string; "box"; rank-value filter 
max #!N OUTPUT output; field; filtered data #!N #!EF #!N #!N 
#!EC #!N #!N The Filter module is assigned to the Transformation 
category. It takes four inputs: #!T,1,161,321,481,641  #!F-adobe-times-bold-r-normal--18*   #!N TAB Module Input 
TAB Type TAB Default TAB Description #!EF #!N TAB input TAB

#!N TAB component TAB string TAB "data" TAB component to be 
operated on #!N TAB mask TAB value or string TAB "box" 
TAB rank-value filter maximum #!N #!N All input parameters but  #!F-adobe-times-bold-r-normal--18*   
input #!EF are assigned default values. The  #!F-adobe-times-bold-r-normal--18*   component #!EF and 
 #!F-adobe-times-bold-r-normal--18*   mask #!EF parameters are hidden by default ([visible:0]). #!N #!N 
The OPTIONS line in the module description specifies possible values for 
the  #!F-adobe-times-bold-r-normal--18*   component #!EF parameter (two in this case). This list 
of values can be accessed by clicking on the  #!F-adobe-times-bold-r-normal--18*   ... 
#!EF button to the right of the  #!F-adobe-times-bold-r-normal--18*   Value #!EF field 
in the module's configuration dialog box. #!N #!N The module description 
for the ShowBox module is: #!CForestGreen #!N #!N  #!F-adobe-courier-bold-r-normal--18*   #!N MODULE 
ShowBox #!N CATEGORY Realization #!N DESCRIPTION draws a bounding box #!N 
INPUT input; field; (none); the field of which to show the 
bounding box #!N OUTPUT box; field; renderable bounding box of input 
field #!N OUTPUT center; vector; center of bounding box #!EF #!N 
#!N #!EC #!N #!N The ShowBox module is assigned to the 
Realization category. It takes an input, named  #!F-adobe-times-bold-r-normal--18*   input #!EF , 
of type  #!F-adobe-times-bold-r-normal--18*   field #!EF . There are two outputs, named 
 #!F-adobe-times-bold-r-normal--18*   box #!EF and  #!F-adobe-times-bold-r-normal--18*   center #!EF , of type  #!F-adobe-times-bold-r-normal--18*   
field #!EF and  #!F-adobe-times-bold-r-normal--18*   vector #!EF respectively. #!N #!N The module 
description for the Options module is: #!CForestGreen #!N #!N  #!F-adobe-courier-bold-r-normal--18*   #!N 
MODULE Options #!N CATEGORY Structuring #!N DESCRIPTION associates attributes with an 
object #!N INPUT input; object; (none); object with attributes to be 
set #!N INPUT attribute; string; (no default); attribute to set #!N 
INPUT value; object; (no default); value of the attribute #!N REPEAT 
2 #!N OUTPUT output; object; the object with attributes set #!EF 
#!N #!N #!EC #!N #!N The Options module is assigned to 
the Structuring category. It has three named parameters, none of which 
is given defaults. The module may take additional pairs of input 
parameters, whose types are the same as the last two inputs 
preceding the  #!F-adobe-times-bold-r-normal--18*   REPEAT #!EF statement. #!N #!N #!N  #!F-adobe-times-medium-i-normal--18*   Next
