In LESS, is it possible to get image dimension from the bitmap files? -


i found myself hard-coding image width numbers in less stylesheet.

it possible have less function automate this? e.g.

@banner-width : image-width("image/banner.png");

if using javascript implementation of less (less.js), use javascript interpolation between back-ticks , use normal javascript functionality - this:

@banner-width: ~`function(imguri){var img=new image(); img.src = imguri; return img.width }('image/banner.png')`;

or go further , make reusable mixins.

less:

.width(@img) {   @width: ~`function(imguri){var img=new image(); img.src = imguri; return img.width }(@{img})`;     width: @width; } .height(@img) {   @height: ~`function(imguri){var img=new image(); img.src = imguri; return img.height }(@{img})`;     height: @height; }  .test{     @src: 'http://www.google.com/intl/en_all/images/logo.gif';     .width(@src);     .height(@src); }

the output css:

.test {   width: 276;   height: 110; }

which should logo http://www.google.com/intl/en_all/images/logo.gif

  • to add units coud add unit(@dimension,px) mixins.

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!
