| - | Use a linestrip element to draw a single point on the map. | ||

| - | The drawing can be written as: | ||
| - | |||
| - | <code XML> | ||
| - | <linestrip color="myPredefinedColor"> | ||
| - | <point x="v0 x" y="v0 y" /> | ||
| - | <point x="v1 x" y="v1 y" /> | ||
| - | <point x="v2 x" y="v2 y" /> | ||
| - | <point x="v3 x" y="v3 y" /> | ||
| - | </linestrip> | ||
| - | </code> | ||

| - | <HTML> | ||
| - | <p style="border:1px dashed #C11B17;color:#C11B17;"> | ||
| - | Use <b>linestrip</b> instead of <b>line</b> to draw continues lines. | ||
| - | The drawing performance will be much better than using single lines as in the old sectorfile format. (much less data to process)<br>This means that if you export an old sectorfile to the new map format, you need to remove the duplicate <point> entries to improve performance. | ||

| - | ===== example ===== | ||
| - | |||
| - | The following code draws a rectangle: | ||
| - | |||
| - | <code XML> | ||
| - | <linestrip color="myPredefinedColor"> | ||
| - | <point lat="N0504413" lon="E0043108"/> | ||
| - | <point lat="N0504421" lon="E0042601"/> | ||
| - | <point lat="N0504528" lon="E0042119"/> | ||
| - | <point lat="N0504730" lon="E0041718"/> | ||
| - | <point lat="N0504413" lon="E0043108"/> | ||
| - | </linestrip> | ||
