<TITLE>masking out part of a MULTILINESTRING</TITLE>
</HEAD>
<BODY>
<P><FONT SIZE=2>Apologies ahead of time if this is a bone headed Q, but I can't get my hands around the function that holds the keys to the kingdom.</FONT></P>
<P><FONT SIZE=2>Say that I have one MULTILINESTRING that contains these vertices:</FONT>
<BR><FONT SIZE=2> (0,0)</FONT>
<BR><FONT SIZE=2> (1,0)</FONT>
<BR><FONT SIZE=2> (2,0)</FONT>
<BR><FONT SIZE=2> (3,0)</FONT>
<BR><FONT SIZE=2> (4,0)</FONT>
<BR><FONT SIZE=2> (5,0)</FONT>
</P>
<P><FONT SIZE=2>Now say that I want to mask out the BBOX that is defined by:</FONT>
<BR><FONT SIZE=2> (1,-1) to (2,1)</FONT>
</P>
<P><FONT SIZE=2>How can I clip the MULTILINESTRING to show me only those lines that are outside the BBOX? If I do a</FONT>
<BR><FONT SIZE=2> not geom. && BBOX...,</FONT>
<BR><FONT SIZE=2>it kills the whole MULTILINESTRING since part of the MULTILINESTRING is inside the BBOX. And that's not what I want.</FONT>
</P>
<P><FONT SIZE=2>I want to end up w/ an image or geom. that has these segments:</FONT>
<BR><FONT SIZE=2> (0,0) to (0,1)</FONT>
<BR><FONT SIZE=2> (2,0) to (5,0)</FONT>
</P>
<P><FONT SIZE=2>Any ideas?</FONT>
</P>
<P><FONT SIZE=2>Thanks,</FONT>
