Save exact image output from imagesc in matlab -


rainbow

hi , want save image produced imagesc(magic(3)), exact rainbow representation, possible?

thanks.

this question might duplicate , not . looked @ solution similar question @ site , did not satisfy me . have looked matlab center , close answer got 1 , @ bottom of http://goo.gl/p907wr

to save figure file (don't matter how created), 1 should do:

saveas(figurehandle,'filename','format')

where figurehandle gcf handle, means: get current figure.

as pointed in discussion, if doesn't want ticks shown, person can add:

set(gca,'xtick',[]) set(gca,'ytick',[])

where gca handle current axis, gcf. if have more 1 axis, don't forget "handle handles". returned when create them, i.e.:

hfig = figure(pairvaluedproperties); % create , figure handle haxes1 = suplot(2,1,1,pairvaluedproperties); % create , upper axes handle haxes2 = suplot(2,1,2,pairvaluedproperties); % create , bottom axes handle

where pair value figure or axes properties declared in following syntax:

'propertyname1',propertyvalue1,'propertyname2',propertyvalue2,…

here matlab documentation figure , axes properties, , saveas method.

example:

the image saved following code:

figure  imagesc(magic(3)) set(gca,'xtick',[]) % remove ticks in x axis! set(gca,'ytick',[]) % remove ticks in y axis set(gca,'position',[0 0 1 1]) % make axes occupy hole figure saveas(gcf,'figure','png')

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!
