| | 5 | == Seeding the Mapguide Tile Cache for a Tiled Map == |
| | 6 | |
| | 7 | The attached script uses OpenLayers to display a tiled map and provides the functionality to pan[[BR]] |
| | 8 | and scan across the entire map, optionally for all scale levels. |
| | 9 | |
| | 10 | The logic is quite simple. Starting for the center of the map, it will pan left, then up and down to[[BR]] |
| | 11 | calculate the number of rows and then right to calculate the number of columns. This could be simply[[BR]] |
| | 12 | calculated but the tiles need to be requested anyway. |
| | 13 | |
| | 14 | Once that is known, the script will then either starting panning left to right down one and then [[BR]] |
| | 15 | right to left and so on to request (and thus seed) the entire map. |
| | 16 | |
| | 17 | There is also an option to use a randomised request pattern. |
| | 18 | |
| | 19 | The attached file is configured to work with the sheboygan sample. |
| | 20 | |
| | 21 | == Future == |
| | 22 | |
| | 23 | The randomised logic could be improved generate the random list once rather than the approach currently used. |
| | 24 | |
| | 25 | Making the script into a fusion widget |
| | 26 | |
| | 27 | Some of a code cleanup :) |
