Scanning

Eugenia: The idea is that the scanner program would be the epiphany not the galeon of scanning. I'm afraid that the target audience is not photographers and advanced users, at least not at the start anyway.

Andy: I'm also having some trouble with sane:

<code>

[sisob@sisob sisob]$ scanimage
scanimage: open of device gt68xx:/dev/usb/scanner0 failed: Error during device I/O
[sisob@sisob sisob]$ dmesg

The scanner does work on other Linux PCs with the same hardware, and it did work once or twice on this PC, but then it stopped. I've even tried resetting my BIOS, but I still get his. Even with multiple distos the same thing ...

re: Eugenia

Eugenia: Sorry, should have been more clear, the scanning program doesn't exist yet. It just a Ui design. The idea was that it would be a frontend to libsane, so it would have what ever features are avaliable with xsane, but with a much prettier interface. Ross said he was thinking about putting some code behind it.

Programming Languages

I know that "every progamming language sucks, each in it's own special way". But I have to say that since I've been learning about object orientation in java it's struck me how UGLY object orientation is in C. Appart from anything else C/Gtk+ is just really hard to read, which to me is a signifigant barrier to entry to hacking.

I was delighted recently to discover how similar C# is to Java. I mean check out gtk#'s hello world, it's just sexy:

<code>
	using Gtk;
	using GtkSharp;
	using System;

	class Hello {

		static void Main()
		{
			Application.Init ();

    			Button btn = new Button ("Hello World");
    			btn.Clicked += new EventHandler (hello);

			Window window = new Window ("helloworld");
			window.DeleteEvent += new DeleteEventHandler (delete_event);
			window.Add (btn);
			window.ShowAll ();

			Application.Run ();
    		}


		static void delete_event (object obj, DeleteEventArgs args)
		{
			    Application.Quit ();
		}

		static void hello (object obj, EventArgs args)
		{
			Console.WriteLine("Hello World");
			Application.Quit ();
		}
	}

</code>

That was taken from the mono handbook. There are some hideous C/Gtk+ hello worlds online too. I always knew I hated trying to hack C/Gtk+, but now I know that there is something better.

I should be a pretty decent Java coder by the end of this (college) year, maybe I'll pickup some C# coding this summer if I'm not working. F-Spot looks very promising and would be great if combined with Original for web publishing, and a Gnome scanning program.

James: ahh, I couldn't see a changelog entry in bonzai but I had the changes locally so I assumed that they had been there for a while. Obviously the changes just hadn't synced to anon-cvs yet.

Nice work on the wiki page...
