javascript - ImageJ API WaitForUserDialog -

-

i'm trying write plugin imagej prompt user select rectangular roi in region in image using rectangular selection tool button built menu bar. here code:

import ij.*; import ij.process.*; import ij.gui.*; import java.awt.*; import ij.plugin.*;  public class computedop implements plugin {  public void run(string arg) {     ij.showmessage("dop plugin status","load image");            imageplus imp = ij.openimage();     imp.show();     ij.showmessage("dop plugin status","phantom loaded, select rectangle roi");           //image roi     waitforuserdialog wait = new waitforuserdialog("select rectangular roi", "please press ok when done.");     wait.show();     roi userroi = impphantom.getroi();      //create profile plot     profileplot pplotphantom = new profileplot(impphantom, true);     double[] phanprofile = pplotphantom.getprofile();    }

my problem focus shifts prompt dialog appears due waitforuserdialog. won't allow user use of menu tools built in imagej. goal halt plugin, , wait user click ok on dialog box appears. however, need user able use rectangle selection tool. should looking other way halt plugin , prompt user select roi?

you should use waitforuserdialog#show() method make sure plugin waits user input , continues after ok pressed.

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl
