The problem is surely a problem of time. But with a Thread.Sleep in the
MakeShot method the problem is not solved cause the sleep stops the
rendering too :)
My solution is too put a button to launch the MakeShot method. It is
less elegant but it works.
Thx
Here is the code.
using System;
using Gtk;
using Gecko;
class Thumbnail {
static WebControl wc;
static string output = "shot.png";
static string url;
static int width = -1;
static int height = -1;
static void Main (string [] args)
{
for (int i = 0; i < args.Length; i++){
switch (args [i]){
case "-width":
try {
i++;
width = Int32.Parse (args [i]);
} catch {
Console.WriteLine ("-width requires an numeric argument");
}
break;
case "-height":
try {
i++;
height = Int32.Parse (args [i]);
} catch {
Console.WriteLine ("-height requires an numeric argument");
}
break;
case "-help":
case "-h":
Help ();
break;

else
