By default ````labelAnchor```` is set so the label will show vertically centered for the default icon (````L.Icon.Default````). - -E.g. Vertically center an icon with ````iconAnchor```` set as the center of the icon: - -````js -var myIcon = L.icon({ - iconUrl: 'my-icon.png', - iconSize: [20, 20], - iconAnchor: [10, 10], - labelAnchor: [6, 0] // as I want the label to appear 2px past the icon (10 + 2 - 6) -}); -L.marker([-37.7772, 175.2606], { - icon: myIcon -}).bindLabel('Look revealing label!').addTo(map); -```` - -When positioning the label L.Label includes a 6px horizontal padding. you will need to take this into account when setting ````labelAnchor````. - -##Setting the opacity of a label - -You can set the opacity of a label by calling the `setOpacity` method on `L.Marker`. By default the opacity will either be **0** or **1**. - -````js -// Sets opacity of marker to 0.3 and opacity of label to 1 -markerLabel.setOpacity(0.3); - -// Sets opacity of marker to 0.3 and opacity of label to 0.3 -markerLabel.setOpacity(0.3, true); - -// Sets opacity of marker to 0 and opacity of label to 0 -markerLabel.setOpacity(0); -markerLabel.setOpacity(0, true); - -// Sets opacity of marker to 1 and opacity of label to 1 -markerLabel.setOpacity(1); -markerLabel.setOpacity(1, true); -```` - -##Alternative label plugin - -My previous label plugin is still available at https://github.com/jacobtoye/Leaflet.iconlabel. This plugin is a little harder to use, however if you want to have both the icon and label bound to the same event this plugin is for you. diff --git a/mapentity/static/mapentity/Leaflet.label/build/build.js b/mapentity/static/mapentity/Leaflet.label/build/build.js deleted file mode 100644 index ebd2ae3c9..000000000 --- a/mapentity/static/mapentity/Leaflet.label/build/build.js +++ /dev/null @@ -1,155 +0,0 @@ -var fs = require('fs'), - jshint = require('jshint'), - UglifyJS = require('uglify-js'), - - deps = require('./deps.js').deps, - hintrc = require('./hintrc.js'); - - -function lintFiles(files) { - - var errorsFound = 0, - i, j, len, len2, src, errors, e; - - for (i = 0, len = files.length; i < len; i++) { - - jshint.JSHINT(fs.readFileSync(files[i], 'utf8'), hintrc.config, hintrc.globals); - errors = jshint.JSHINT.errors; - - for (j = 0, len2 = errors.length; j < len2; j++) { - e = errors[j]; - console.log(files[i] + '\tline ' + e.line + '\tcol ' + e.character + '\t ' + e.reason); - } - - errorsFound += len2; - } - - return errorsFound; -} - -function getFiles(compsBase32) { - var memo = {}, - comps; - - if (compsBase32) { - comps = parseInt(compsBase32, 32).toString(2).split(''); - console.log('Managing dependencies...'); - } - - function addFiles(srcs) { - for (var j = 0, len = srcs.length; j < len; j++) { - memo[srcs[j]] = true; - } - } - - for (var i in deps) { - if (comps) { - if (parseInt(comps.pop(), 2) === 1) { - console.log('\t* ' + i); - addFiles(deps[i].src); - } else { - console.log('\t ' + i); - } - } else { - addFiles(deps[i].src); - } - } - - var files = []; - - for (var src in memo) { - files.push('src/' + src); - } - - return files; -} - -exports.lint = function () { - - var files = getFiles(); - - console.log('Checking for JS errors...'); - - var errorsFound = lintFiles(files); - - if (errorsFound > 0) { - console.log(errorsFound + ' error(s) found.\n'); - fail(); - } else { - console.log('\tCheck passed'); - } -}; - - -function getSizeDelta(newContent, oldContent) { - if (!oldContent) { - return 'new'; - } - var newLen = newContent.replace(/\r\n?/g, '\n').length, - oldLen = oldContent.replace(/\r\n?/g, '\n').length, - delta = newLen - oldLen; - - return (delta >= 0 ?
