ruby on rails 3 - MiniMagic resize -


im using minimagick resize images on server. having issues forcing dimensions on it. minimagick git documentation states uses mogrify commands. looking further, there sever commands can use in resize such as:

-resize "230x200>" -resize "230x200<" -resize "230x200!"

i looking use ! seems not working. 

     img = sftp.download!("local_promos/#{@image_name}")        ri = minimagick::image.read(img)      ri.resize "230x200!" # ! ignored , not resize      ri.write('#{img_dir}#{@image_name}')

i ran mogrify command in command , worked fine. seems issue?

the problem gem mini_magic. using -v 3.5.0. escaping string using shellwords.escape(value.to_s) newer version 3.6.0 fixed issue.

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!
