Status](https://secure.travis-ci.org/mapbox/carto.png)](http://travis-ci.org/mapbox/carto)\n\nIs as stylesheet renderer for javascript, It's an evolution of the Mapnik renderer from Mapbox.\nPlease, see original [Mapbox repo](http://github.com/mapbox/carto) for more information and credits\n\n## Quick Start\n\n```javascript\n// shader is a CartoCSS object\n\nvar cartocss = [\n '#layer {',\n ' marker-width: [property]',\n ' marker-fill: red',\n '}'\n].join('')\nvar shader = new carto.RendererJS().render(cartocss);\nvar layers = shader.getLayers()\nfor (var i = 0; i < layers.length; ++i) {\n var layer = layers[i];\n console.log(\"layer name: \", layer.fullName())\n console.log(\"- frames: \", layer.frames())\n console.log(\"- attachment: \", layer.attachment())\n\n var layerShader = layer.getStyle({ property: 1 }, { zoom: 10 })\n console.log(layerShader['marker-width']) // 1\n console.log(layerShader['marker-fill']) // #FF0000\n}\n\n```\n\n# API\n\n## RendererJS\n\n### render(cartocss)\n\n## CartoCSS\n\ncompiled cartocss object\n\n### getLayers\n\nreturn the layers, an array of ``CartoCSS.Layer`` object\n\n### getDefault\n\nreturn the default layer (``CartoCSS.Layer``), usually the Map layer\n\n\n### findLayer(where)\n\nfind a layer using where object.\n\n```\nshader.findLayer({ name: 'test' })\n```\n\n## CartoCSS.Layer\n\n### getStyle(props, context)\n\nreturn the evaluated style:\n - props: object containing properties needed to render the style. If the cartocss style uses\n some variables they should be passed in this object\n - context: rendering context variables like ``zoom`` or animation ``frame``\n\n\n\n\n\n\n\n\n\n\n## Reference Documentation\n\n* [mapbox.com/carto](http://mapbox.com/carto/)\n\n\n",readmeFilename:"README.md",bugs:{url:"https://github.com/mapbox/carto/issues"},homepage:"https://github.com/mapbox/carto",_id:"carto@0.14.0",_shasum:"1f03e0a82222fcef0cb11580e54c3a12d5b32ffb",_from:"https://github.com/CartoDB/carto/archive/update_to_master.tar.gz",_resolved:"https://github.com/CartoDB/carto/archive/update_to_master.tar.gz"}},{}]},{},[10])(10)}); \ No newline at end of file +!function(e){if("object"==typeof exports&&"undefined"!=typeof module)module.exports=e();else if("function"==typeof define&&define.amd)define([],e);else{var t;"undefined"!=typeof window?t=window:"undefined"!=typeof global?t=global:"undefined"!=typeof self&&(t=self),t.torque=e()}}(function(){var define,module,exports;return function e(t,n,r){function i(o,u){if(!n[o]){if(!t[o]){var a=typeof require=="function"&&require;if(!u&&a)return a(o,!0);if(s)return s(o,!0);var f=new Error("Cannot find module '"+o+"'");throw f.code="MODULE_NOT_FOUND",f}var l=n[o]={exports:{}};t[o][0].call(l.exports,function(e){var n=t[o][1][e];return i(n?n:e)},l,l.exports,e,t,n,r)}return n[o].exports}var s=typeof require=="function"&&require;for(var o=0;oe&&this.time(0),this.rescale(),this):this.options.animationDuration},steps:function(e){return this.options.steps=e,this.rescale()},step:function(e){if(arguments.length===0)return this.range(this.domain(this._time));this._time=this.domainInv(this.rangeInv(e))},pause:function(){this.running=!1,s(this._tick),this.options.onPause&&this.options.onPause()},_tick:function(){var e=+(new Date),t=(e-this._t0)*.001;t=Math.min(this.options.maxDelta,t),this._t0=e,this._time+=t,this.step()>=this.options.steps&&(this._time=0,this.options.loop||this.stop()),this.running&&(this.time(this._time),i(this._tick))}},t.exports=o}).call(this,typeof global!="undefined"?global:typeof self!="undefined"?self:typeof window!="undefined"?window:{})},{"./":10}],2:[function(e,t,n){var r={version:"1.0.0",style:{"comp-op":{css:"comp-op","default-value":"src-over","default-meaning":"add the current layer on top of other layers",doc:"Composite operation.

Status](https://secure.travis-ci.org/mapbox/carto.png)](http://travis-ci.org/mapbox/carto)\n\nIs as stylesheet renderer for javascript, It's an evolution of the Mapnik renderer from Mapbox.\nPlease, see original [Mapbox repo](http://github.com/mapbox/carto) for more information and credits\n\n## Quick Start\n\n```javascript\n// shader is a CartoCSS object\n\nvar cartocss = [\n '#layer {',\n ' marker-width: [property]',\n ' marker-fill: red',\n '}'\n].join('')\nvar shader = new carto.RendererJS().render(cartocss);\nvar layers = shader.getLayers()\nfor (var i = 0; i < layers.length; ++i) {\n var layer = layers[i];\n console.log(\"layer name: \", layer.fullName())\n console.log(\"- frames: \", layer.frames())\n console.log(\"- attachment: \", layer.attachment())\n\n var layerShader = layer.getStyle({ property: 1 }, { zoom: 10 })\n console.log(layerShader['marker-width']) // 1\n console.log(layerShader['marker-fill']) // #FF0000\n}\n\n```\n\n# API\n\n## RendererJS\n\n### render(cartocss)\n\n## CartoCSS\n\ncompiled cartocss object\n\n### getLayers\n\nreturn the layers, an array of ``CartoCSS.Layer`` object\n\n### getDefault\n\nreturn the default layer (``CartoCSS.Layer``), usually the Map layer\n\n\n### findLayer(where)\n\nfind a layer using where object.\n\n```\nshader.findLayer({ name: 'test' })\n```\n\n## CartoCSS.Layer\n\n### getStyle(props, context)\n\nreturn the evaluated style:\n - props: object containing properties needed to render the style. If the cartocss style uses\n some variables they should be passed in this object\n - context: rendering context variables like ``zoom`` or animation ``frame``\n\n\n\n\n\n\n\n\n\n\n## Reference Documentation\n\n* [mapbox.com/carto](http://mapbox.com/carto/)\n\n\n",readmeFilename:"README.md",bugs:{url:"https://github.com/cartodb/carto/issues"},homepage:"https://github.com/cartodb/carto",_id:"carto@0.15.1",_shasum:"0d59e5d119c8254dbb15a0ebd5fe21c4b9c4c3d4",_resolved:"https://github.com/CartoDB/carto/archive/master.tar.gz",_from:"https://github.com/CartoDB/carto/archive/master.tar.gz"}},{}]},{},[10])(10)}); \ No newline at end of file diff --git a/dist/torque.full.uncompressed.js b/dist/torque.full.uncompressed.js new file mode 100644 index 0000000..329414b --- /dev/null +++ b/dist/torque.full.uncompressed.js @@ -0,0 +1,13654 @@ +!function(e){if("object"==typeof exports&&"undefined"!=typeof module)module.exports=e();else if("function"==typeof define&&define.amd)define([],e);else{var f;"undefined"!=typeof window?f=window:"undefined"!=typeof global?f=global:"undefined"!=typeof self&&(f=self),f.torque=e()}}(function(){var define,module,exports;return (function e(t,n,r){function s(o,u){if(!n[o]){if(!t[o]){var a=typeof require=="function"&&require;if(!u&&a)return a(o,!0);if(i)return i(o,!0);var f=new Error("Cannot find module '"+o+"'");throw f.code="MODULE_NOT_FOUND",f}var l=n[o]={exports:{}};t[o][0].call(l.exports,function(e){var n=t[o][1][e];return s(n?n:e)},l,l.exports,e,t,n,r)}return n[o].exports}var i=typeof require=="function"&&require;for(var o=0;o _) { + this.time(0); + } + this.rescale(); + return this; + }, + + steps: function(_) { + this.options.steps = _; + return this.rescale(); + }, + + step: function(s) { + if(arguments.length === 0) return this.range(this.domain(this._time)); + this._time = this.domainInv(this.rangeInv(s)); + }, + + pause: function() { + this.running = false; + cancelAnimationFrame(this._tick); + this.options.onPause && this.options.onPause(); + }, + + _tick: function() { + var t1 = +new Date(); + var delta = (t1 - this._t0)*0.001; + // if delta is really big means the tab lost the focus + // at some point, so limit delta change + delta = Math.min(this.options.maxDelta, delta); + this._t0 = t1; + this._time += delta; + if(this.step() >= this.options.steps) { + this._time = 0; + if(!this.options.loop){ + this.stop(); + } + } + if(this.running) { + this.time(this._time); + requestAnimationFrame(this._tick); + } + } + + }; + +module.exports = Animator; + +}).call(this,typeof global !== "undefined" ? global : typeof self !== "undefined" ? self : typeof window !== "undefined" ? window : {}) +},{"./":10}],2:[function(require,module,exports){ +var _torque_reference_latest = { + "version": "1.0.0", + "style": { + "comp-op": { + "css": "comp-op", + "default-value": "src-over", + "default-meaning": "add the current layer on top of other layers", + "doc": "Composite operation.
