Thread: Loading in images

I have 2 questions about loading in images..

First of all is there a way to load images in 3 dimensional matrices ? As in matlab?
Here is a piece of a matlab 'script' I made to make a puzzle from an images:

function [] = puzzel(naam, N);
afb = imread(naam);
resolutie = size(afb);
afm = resolutie(1);
 
x = sqrt(N);
 
for i = 1:3
    for j=1:afm/x
        for k=1:afm/x
            afb(afm-afm/x+j,afm-afm/x+k,i) = 0;
        end;
    end;
end;
 
randm = fix(rand(1)*40+10)
for o = 1:randm
hop1= floor(rand*(x))+1;
hop2= floor(rand*(x))+1;
hip1= floor(rand*(x))+1;
hip2= floor(rand*(x))+1;
for i = 1:3
    for j=1:afm/x
        for k=1:afm/x
        im1 = afb(afm-hop1*afm/x+j,afm-hop2*afm/x+k,i);
        im2 = afb(afm-hip1*afm/x+j,afm-hip2*afm/x+k,i);
        afb(afm-hop1*afm/x+j,afm-hop2*afm/x+k,i) = im2;
        afb(afm-hip1*afm/x+j,afm-hip2*afm/x+k,i) = im1;
        end;
    end;
end;
end;
image(afb);

Now as you can see, afb contains the image, and afb is a 3 dimensional matrix : ) x:y:1 -> red x:y:2 -> green, etc

Is there a way to do the same with java?

Another thing, if there is a way (of if there isn't, referring to the previous question).
Is there a way to load the image that is currently in your clipboard ?

Loading things from the Clipboard can sometimes be a pain, but look at the Clipboard (Java 2 Platform SE 5.0).If you are doing this through an applet you will most likely have security issues in which you must sign the applet for Clipboard access.

As far is a 3D image, I don't think Java has a standard class, but you could create your own through either arrays representing the 3D architecture of the RGB values, or create an array of BufferedImage (Java 2 Platform SE v1.4.2)

Since I have no experience with images in java I'll give that bufferedimages a try.

Btw, 3d images? Are you sure you know what I meant..? The images are clearly just 2d, but they get represented by a 3d matrix, because every pixel get's represented by 3 colours, red green blue, anyway, I'll do some research on that
