<DIV><FONT face="Times New Roman" color=#000000 size=3>Hello, just to further clarify this point:</FONT></DIV>
<DIV> </DIV>
<DIV>This is the method currently used to generate a curve when gvSIG reads an Oracle Spatial curve:</DIV>
<DIV> </DIV>
<DIV><A href="http://java.sun.com/j2se/1.5.0/docs/api/java/awt/geom/GeneralPath.html#quadTo%28float,%20float,%20float,%20float%29">http://java.sun.com/j2se/1.5.0/docs/api/java/awt/geom/GeneralPath.html#quadTo%28float,%20float,%20float,%20float%29</A></DIV>
<DIV> </DIV>
<DIV>which is not the type of curve intended by Oracle Spatial. To achieve the correct type of curve, this method should be used:</DIV>
<DIV> </DIV>
<DIV><A href="http://java.sun.com/j2se/1.5.0/docs/api/java/awt/geom/GeneralPath.html#append%28java.awt.Shape,%20boolean%29">http://java.sun.com/j2se/1.5.0/docs/api/java/awt/geom/GeneralPath.html#append%28java.awt.Shape,%20boolean%29</A></DIV>
<DIV> </DIV>
<DIV>where Shape would be an Arc2D, but this needs some additional computation because Arc2D cannot be created directly from 3 points of it (as Oracle Spatial does)</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>As for bicubic splines, in which CAD formats are they defined? I don't know if gvSIG CAD drivers read them properly. Can you send a sample CAD file with one of those splines?</DIV>
<DIV> </DIV>
<DIV> </DIV>

<P><FONT size=2>Hi all,<BR>now this sounds interesting.<BR>I am not a programmer so I wonder if you could use or modify java2d to deal<BR>with bicubic splines which are often used in CAD-drawings.<BR>Can anyone comment on this subject?<BR><BR>Best,<BR><BR>Johannes<BR>--<BR>View this message in context: <A href="http://osgeo-org.1803224.n2.nabble.com/Oracle-Arc-s-tp5109729p5112243.html">http://osgeo-org.1803224.n2.nabble.com/Oracle-Arc-s-tp5109729p5112243.html</A><BR>Sent from the gvSIG international mailing list archive at Nabble.com.<BR>_______________________________________________<BR>Gvsig_internacional mailing list<BR>Gvsig_internacional@listserv.gva.es<BR><A href="http://listserv.gva.es/cgi-bin/mailman/listinfo/gvsig_internacional">http://listserv.gva.es/cgi-bin/mailman/listinfo/gvsig_internacional</A><BR></FONT></P></DIV></BODY></HTML>
