can you explain the track clipping algorithm ?</blockquote><div><br>Do you mean the yellow dots for GPX tracks?<br></div><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
My first thought was that it is a scale dependent<br>thing,<br>but it is not. </blockquote><div><br>Well it is actually, kind of.<br></div><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
Very often the long tracks which are<br>definitely inside the canvas "bounding box" are<br>invisible, but a simple move makes them visible again,<br>while others disappear.</blockquote><div><br>I think the current renderer only displays the most recent 50000, which will vary from bounding box to bounding box.
