javascript - Draggable font on RaphaelJS -



javascript - Draggable font on RaphaelJS -

im trying create text added using print() draggable. i've found post code doesn't work - i've reposted fiddle - on chrome , ff text flies off screen. if set getbbox() parameter false works first drag then, on subsequent drags, mouse offset.

var w = document.body.clientwidth, h = document.body.clientheight, paper = raphael(0, 0, w, h); var font = paper.getfont("vegur"); var text = paper.print(20,20,"my dragable text",font,50); var start = function () { text.obb = text.getbbox(); }, move = function (dx, dy) { var bb = text.getbbox(true); // setting false works 1 time text.transform('...t'+[text.obb.x - bb.x + dx, text.obb.y - bb.y + dy]); }, = function () { }; text.drag(move, start, up);

figured out...

var start = function() { //get original position before transform var obb = this.getbbox(true); //get position after lastly transform var nbb = this.getbbox(false); //store difference this.ox = nbb.x - obb.x this.oy = nbb.y - obb.y; }, move = function(dx, dy) { //apply difference mouse moves this.transform('t' + [this.ox + dx, this.oy + dy]); }, = function() { };

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
