SLURL Raster Image Generator

//SLURL Tile URL Generator - By Kerik Rau

//Based on the javascript from, 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
    string mapURL = "";
    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;

        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());
