\r
77 <p>Selection filter library is a powerful tool enabling to create filters
\r
78 to be used on meshes. You can access to it from the Main Menu via <span
\r
79 style="font-weight: bold;"><B>Tools / Selection filter library</B></span> </p>
\r
83 <p><img src="pics/a-filteronedges.png" x-maintain-ratio="TRUE" width="624px" height="525px" border="0" class="img_whs1"></p>
\r
87 <p>In this dialog window</p>
\r
89 <p class="whs2">Library file name s<span style="font-weight: normal;">hows
\r
90 the path and the file name where your filters will be stored. By clicking
\r
91 the</span> <img src="image103.gif" width="31px" height="30px" border="0" class="img_whs3"> <span style="font-weight: normal;">browse button
\r
92 you can load an existing filter library.</span></p>
\r
94 <p><span style="font-weight: bold;"><B>Names of filters</B></span> lists the filters
\r
95 created or uploaded for the current study. You can <span style="font-weight: bold;"><B>Add</B></span>
\r
96 or <span style="font-weight: bold;"><B>Delete</B></span> filters. </p>
\r
98 <p>In <span style="font-weight: bold;"><B>Filter name</B></span> box you can specify
\r
99 the name for your filter. By default it is prefixed with the corresponding
\r
102 <p>Each filter can be applicable to <span style="font-weight: bold;"><B>Nodes,
\r
103 Edges, Faces</B></span> or <span style="font-weight: bold;"><B>Volumes</B></span>.
\r
104 You can combine many criteria in one filter, but they all must be of the
\r
105 same <span style="font-weight: bold;"><B>Entity type</B></span>. The <span style="font-weight: bold;"><B>Add</B></span>
\r
106 button creates a new criterion at the end of the list of criteria. The
\r
107 <span style="font-weight: bold;"><B>Insert</B></span> button creates a new criterion
\r
108 after the selected criterion. The <span style="font-weight: bold;"><B>Remove</B></span>
\r
109 button deletes the selected criterion. The <span style="font-weight: bold;"><B>Clear</B></span>
\r
110 button deletes all criteria. </p>
\r
112 <p>Each <span style="font-weight: bold;"><B>Entity type</B></span> has its specific
\r
113 list of criteria, however all filters have common syntax. For each criterion
\r
114 you should specify the <span style="font-weight: bold;"><B>Threshold Value</B></span>
\r
115 and whether we search for the elements that should be <span style="font-weight: bold;"><B>More,
\r
116 Less or Equal</B></span> to this Value. You should also specify if the criterion
\r
117 is <span style="font-weight: bold;"><B>Unary</B></span> or <span style="font-weight: bold;"><B>Binary.</B></span>
\r
120 <p>Some criteria should have the additional parameter of <span style="font-weight: bold;"><B>Tolerance</B></span>.</p>
