javascript - jsPDF dotted line (setLineCap) -

i have question jspdf use generate pdf files.

there 1 thing blocked on, it's creation of lines. can using line function, works, apply style on lines, particularly make dotted line.

looking in api, found setlinecap(style) function looks 1 looking for, nothing applied on lines.

so in code have :

doc.setlinecap("round"); doc.line(20, rowposition+4, linewidth, rowposition+4); 

the line appears right, line.

does know how make works ?

for additional informations, here api code :

/**     object providing mapping human-readable     integer flag values designating varieties of line cap     , join styles.      @returns {object}     @fieldof jspdf#     @name capjoinstyles     */     api.capjoinstyles = {         0: 0,         'butt': 0,         'but': 0,         'bevel': 0,         1: 1,         'round': 1,         'rounded': 1,         'circle': 1,         2: 2,         'projecting': 2,         'project': 2,         'square': 2,         'milter': 2     };      /**     sets line cap styles     see {jspdf.capjoinstyles} variants      @param {string|number} style string or number identifying type of line cap     @function     @returns {jspdf}     @methodof jspdf#     @name setlinecap     */     api.setlinecap = function (style) {         var id = this.capjoinstyles[style];         if (id === undefined) {             throw new error("line cap style of '" + style + "' not recognized. see or extend .capjoinstyles property valid styles");         }         linecapid = id;         out(id.tostring(10) + ' j');          return this;     }; 

i've tried numbers in parameter of function. still doesn't work. hope able me :)

thank !
