I am building a Gis for road navigation When diplaying gthe poylines
To clip According to me there are two ways;
Which i have come about:
1:) to clip the polylines in the world domain ie when they are still
defined in terms of longitudes and latitudes.
2:) To clip the polylines in the page domain that is after converting
the polylines into the page cordinates(a Picture box)
I think the second way is better and efficient in my case as it will
be more efficient because unessary points need not to be converted and
as the i m going to see an area of about 60 * 60 meters usually
(ususally the case with road navigation)
1:) Can anyone tell me if im right or wrong??
2:)How to clip in the world domain (im stuck how to get the
intersection with the clip rectangle
