javascript - how can I position objects in raphael.js related to center -


when set x, y values objects position them on paper, measures x, y top left corner. there way change position related center middle of paper?

raphael has rectangles, circles, , ellipses.

  • latter 2 positioned center coordinates, have nothing worry about.
  • rectangle positioned based on top left corner coordinates

so answer question:

raphael not provide way position rectangle center coordinates.
however can easily.
@ demo.

for example:

// lets assume center coordinates cx , cy var rec = paper.rect(cx, cy, 120, 80);  // position in middle, var rec = paper.rect(cx - 120/2, cy - 80/2, 120, 80);

it simple that. luck!

edit

if want in project, raphael.js , override rectangle class.

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!
