SLURL Raster Image Generator
//SLURL Tile URL Generator - By Kerik Rau //Based on the javascript from SLURL.com, mearly an adaptation in LSL //It should only take a minute or 2 to export this into PHP or other languages //SLURL uses WMS, I still want to look at incorperating it into something like Mapguide //I will need to look at the implementation to see if this would be easy or a pain vector genTileVec(vector RegPos) { //tiles are in a grid based on the regions, so 256m = 1 tile RegPos /= 256.0; //offset provided in the javascript, really 1278 + 1 (probably 0 -> 1 index difference?) RegPos.y = 1279.0 - RegPos.y; return RegPos; } string genMapURL() { vector TilePos = genTileVec(llGetRegionCorner()); //should look like http://secondlife.com/apps/mapapi/grid/map_image/x-y-zoom-0 string mapURL = "http://secondlife.com/apps/mapapi/grid/map_image/"; mapURL += (string) llFloor(TilePos.x); mapURL += "-"; mapURL += (string) llFloor(TilePos.y); //the 3rd value is something to do with zoom, but only 1 seems to work with this //the 4th value is undefined, omitting it works but I leave it in to match SLURL mapURL += "-1-0"; return mapURL; } default { state_entry() { llSetText("SLURL Raster Image URL Generator\nOpens the image of the current sim\n(in a browser)", <1,1,1>, 1); } touch_start(integer numdet) { integer i; for(i = 0; i < numdet; ++i) llLoadURL(llDetectedKey(i), "load this page to see the sim image", genMapURL()); } }
