agl’s jbig2enc is an encoder for JBIG2:
www.jpeg.org/public/fcd14492.pdf

JBIG2 encodes bi-level (1 bpp) images using a number of clever tricks to get
better compression than G4. This encoder can:
* Generate JBIG2 files, or fragments for embedding in PDFs
* Generic region encoding
* Perform symbol extraction, classification and text region coding
* Perform refinement coding and,
* Compress multipage documents

It uses the (Apache-ish licensed) Leptonica library:
http://www.leptonica.com/

Jbig2enc can convert other format image to jbig2 or fragments for embedding in PDFs, and pdf.py can convert the fragments to PDF document.
for example, if you want to convert a.bmp to pdf, you can do it in this way
jbig2 -s -p a.bmp
you get output.0000 and output.sym files
python pdf.py output>jbig2.pdf
btw, itext and itextsharp also supports convert jbig2 to pdf now.
After some efforts, I have successfully compiled jbig2 under Window XP with GCC 4.2(MingW32+MSYS), for details and download, please visit Windows version of agl’s jbig2enc, from this page, you can also download the linux compiled version.

This is a index page of my mono and asp.net articles, so I will continue update this page when I have new articles.

1.Prepare a CentOS hosting, in my case, I use CentOS VPS, I have introduced how to install OpenVZ and Create VPS before.

2.Install Mono 2.4.2.3 on CentOS 5.

3.Install XSP, mod_mono and configure Apache to run ASP.NET application with Apache web server.

P.S.
Q:Why I choose VPS?
A:It can make me easily and quickly roll back the installation(to the last correct snapshot) when I make mistake with the help of vzdump.

In the last article, I have introduced How to Install Mono 2.4.2.3 on CentOS 5 , forgot telling you, why I want to install Mono on CentOS, I want to try to run ASP.NET under Linux.

Mono has an implementation of ASP.NET 2.0 and ASP.NET AJAX, and to run your ASP.NET applications with Mono, you have three classes of options:

• Apache hosting: use mod_mono, a module that allows Apache to serve ASP.NET applications.
• FastCGI hosting: use the FastCGI hosting if you have a web server that supports the FastCGI protocol for extending the server. You also may use a web server that only has support for CGI using cgi-fcgi.
• XSP: this is a simple way to get started, a lightweight and simple webserver written in C#.

XSP is a standalone web server written in C# that can be used to run your ASP.NET applications with minimal effort.
The mod_mono Apache module is used to run ASP.NET applications within the Apache (http://httpd.apache.org) web server.

Let’s continue install XSP and mod_mono now.
1.Go to this page and download xsp-2.4.2.tar.bz2,
#wget http://ftp.novell.com/pub/mono/sources/xsp/xsp-2.4.2.tar.bz2

2. Extract the download file,
# tar jxvf xsp-2.4.2.tar.bz2

3. In to the xsp-2.4.2 folder,
#cd xsp-2.4.2

4.configure, build and install XSP,
# ./configure –prefix=/opt/mono; make; make install
because I installed mono in /opt/mono, so the same treat to XSP

5.go to the parent folder,
#cd ..

6.by default, Apache 2 has been installed, make sure you have installed httpd-devel, or you will get error message like”**** apxs was not found,” when you build mod_mono,
#yum -y install httpd-devel

7.Go to this page and download mod_mono-2.4.2.tar.bz2

8. Extract the download file,
# tar jxvf mod_mono-2.4.2.tar.bz2

9. In to the mod_mono-2.4.2 folder,
#cd mod_mono-2.4.2

10.configure, build and install mod_mono,
# ./configure –prefix=/opt/mono; make; make install

11.You may want to verify a few thigns to make sure the configuration is ready to rock. In my case, I am keeping the mono configuration in a separate file for sanity sake. You can do that or put it all in your httpd.conf, it’s up to you,

12.restart httpd service,
#service httpd restart

13.Test it,
visit http://aspx.yoursite.com/demo in your browser, and if you get the page with the title “Welcome to Mono XSP!”, congratulation!
