javascript - Drawing a polygon with circles using java script canvas -


hi there way draw polygon circles using java script canvas, refer each circle object contains coordinates , index inside. want draw complete k-partite graphs visually. thanks

the canvas works lot in ms paint. once draw circle on computer forgets circle , remembers pixels. need keep track of yourself:

i haven't tested code below idea.

hopefully helps started: http://blog.nihilogic.dk/2009/02/html5-canvas-cheat-sheet.html

var canvas = document.getelementbyid("maincanvas"); var ctx = canvas.getcontext("2d"); var circles =[]; function addcircle(arg_x,arg_y,arg_rad){     var newcirc = {};     newcirc.x = arg_x     newcirc.y = arg_y     newcirc.rad = arg_rad     circles.push(newcirc) }  function redrawcirc(){     // loop through circles array , redraw entire graph     // whenever changes     for(var =0;i<circles.length;i++){         ctx.arc(circles[i].x,circles[i].y,circles[i].rad,0,math.pi*2);     } }

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
