Operating on lines in an image slice

[Ethan Cohen]

I am working with a stack of images.
For each slice from the stack,

1. I want to scrool through each line of the slice from top to bottom and:
2. Box select a horizontal line segment of (pixel thickness 1) of the image.

3. Shift it horizontally by an arbitrary amount (from another array variable) and paste it back in place.  


So I can:
selectWindow();
//setTool("rectangle");
makeRectangle(0, 265, 400, 1);
run("Copy");

But then how do I copy it back into the same line, say shifted 10 pixels horizontally?

run("Paste", 10, 265, 400, 1);?

Subarray.

Ethan,

Try this
for(i=1;i<nSlices();i++){
        getSelectionBounds(x, y, width, height);
        deltax=10;(some calculated thingy)
        newx=x+deltax;
        setSlice(i);
setSelectionLocation(newx, y);
run("Draw","slice");
//or makeRectangle(newx,y, width, height)
}
