unity3d - IOS (IPad) How to load a screenshot created at runtime into a Texture or Texture2D -

-

we facing issue unity. developing ipad app. 1 feature take screenshot , use button. because tree directory in ipad doesn't exist resources folder, can't use "resources.load", , so, because how feature must work, texture won't available @ beginning, can't put in resources folder. have tried several solutions, creating in ipad resources folder (inside documents folder) , trying load texture it, or piece of code:

public texture loadtexturefromfile(string filename) {     texture2d texture = new texture2d(1024, 768);     filestream fs = new filestream(filename, filemode.open, fileaccess.read);      byte[] imagedata = new byte[fs.length];     fs.read(imagedata, 0, (int)fs.length);     texture.loadimage(imagedata);     return (texture texture); }

any appreciated. we've been stuck issue several days

you can try following:

texture2d tex = new texture2d(screen.width, screen.height); tex.readpixels(new rect(0, 0, screen.width, screen.height), 0, 0); tex.apply();

and put tex on button.

if want save file use later on, can do:

// encode texture png var bytes = tex.encodetopng(); destroy( tex );

you'll have png-file can use want.

when saved file , want load somewhere documents folder, can try following:

www imagetoloadpath = new www(/var/mobile/applications/xxxxyyyy-xxxx-xxxx-xxxx-xxxxyyyyzzzz/documents/sample.png) //rendering texture yield return imagetoloadpath; // <- actual load of file imagetoloadpath.loadimageintotexture(buttonobject.renderer.material.maintexture texture2d);

those x's , y's id code of application. when you've run application once, can find folder in application.datapath. peek in there , check need fill in.

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2
