javascript - Use Fabric.js freeDraw how to remove controls and borders - 


/**   * created xj on 2017/9/11.   */  var circle,origx,origy;  prototypefabric.circle={      drawcircle:function(){          circlemode=true;      },      addcenterpoint:function(options){          var pointer=canvas.getpointer(options.e);          origx=pointer.x;          origy=pointer.y;          circle= new fabric.circle({              radius: 1,              fill: '',              stroke: 'red',              strokewidth: 1,              left: pointer.x,              top: pointer.y,              originx:'center',              originy:'center',              selectable: false,              hasborders: false,              hascontrols: false          });          canvas.add(circle);        },      generatecircle:function(options){          var pointer=canvas.getpointer(options.e);          var r=calculate.linelength(origx,origy,pointer.x,pointer.y).tofixed(2);          text=new fabric.text('radius'+r+'('+origx.tofixed(2)+','+origy.tofixed(2)+')',{left:pointer.x,top:pointer.y,fontsize:12,hasborders: false,              hascontrols: false});          canvas.add(text);            circle.set({              radius:calculate.linelength(origx,origy,pointer.x,pointer.y).tofixed(2),              selectable: true,              hasborders: false,              hascontrols: false          });          canvas.selection = true;      }  }

this main function, have set controls, hope when drawing down,it has no borders,and haven't controled, can selectable , scale when mousedown, when down ,it have borders , controls, 1 tell me mistake is, thanks

var prototypefabric = new function () {      this.initcanvas = function () {          canvas = window._canvas = new fabric.canvas('c');          canvas.setwidth($("#mycanvas").width());          canvas.setheight($(window).height()-$(".div_header").height()-$(".canvas_header").height()-$(".canvas_footer").height());          //canvas.selection = false;            canvas.on('mouse:down', function (options) {              startx=options.e.x;              starty=options.e.y;                            if(circlemode){                  isdown=true;                  prototypefabric.circle.addcenterpoint(options);              }          });          canvas.on('mouse:up', function (options) {              circlemode=false;              isdown=false;          });          canvas.on('mouse:move', function (options) {                           canvas.remove(text);              canvas.renderall();                if(circlemode&&isdown){                  prototypefabric.circle.generatecircle(options);                  canvas.renderall();              }              canvas.renderall();          });      };    };  var calculate={      linelength:function(x1,y1,x2,y2){          return math.sqrt(math.pow(x2-x1,2)+math.pow(y2-y1,2))      }  };

the above mouse event,when $('.create-circle') click, begin draw circle, canvas mousedown set isdown=true;

    $('.create-circle').click(function() {          polygonmode = false;          linemode=false;          //circlemode=true;          prototypefabric.circle.drawcircle();      });

minify - Minimizing css files -

i want know how css files can minimized. currently, using external sites css minifier compress css files. however, after removing whitespaces, comments, etc, file sizes reduced 10-15%. how frameworks bootstrap manage make minimized versions kilobytes. as example, css is: body { background-color: #ff0; } the reduction goes 28 bytes 22 bytes other css files have lot more characters still smaller this. actually minifying code means it's remove thing code white space characters new line characters comments block delimiters it reduces amount of code has transferred on web , speed site load fastly.but unreadable format.
