Bindings for other programing languages

Introduction

So far, libharu provides bindings for Ruby, Delphi/Free Pascal and C#(Microsoft .NET platform).

If you wrote bindings for other programing languages, please notice me.

Ruby (1.8 or later)

On UNIX platform, exconf.rb is available. The installation process is as follows.
 
1. Build libharu as a static library. (See the chapter of "Install")

NOTE:
In linux platform, adding -fPIC option on cflags is recommended for the performance improvement.

2. Change directory to "libharu-X.X.X/if/ruby" and run extconf.rb.

ruby extconf.rb

3. Then invoke "make install" command.

make install


If you want to use "Ruby binding for Haru" on windows platforms, download binary package (libharu_x_x_x_ruby_win32.zip) and copy hpdf.so to "site_ruby/X.X/i386-msvcrt" directory manually. (This package is for ruby1.8 built by MSVC)
 
exconf_msvc.rb is also available. but it is not tested well.

Delphi/Free Pascal

The interface files for Delhp/Free Pascal are in "if/delphi" directory.
To use this interface, build Haru as a shared-library (DLL) or use binary package for win32(libharu_x_x_x_dll_win32.zip).


C#

The interface files for C# are in "if/c#" directory.
To use this interface, build Haru as a shared-library (DLL) or use binary package for win32(libharu_x_x_x_dll_win32.zip).

There are some example programs in demo directory. The steps to run the demonstration programs is as follows.

1. Build libharu as a shared library and copy libhpdf.dll to "if\c#\demo" directory.
   (Or expand binary package for win32(libharu_x_x_x_dll_win32.zip) and copy libhpdf.dll to "if\c#\demo" directory.)

2. Compile and run demo programs. (Don't forget to compile hpdf.cs together.)

csc /out:FontDemo.exe FontDemo.cs ..\hpdf.cs
FontDemo.exe

csc /out:ImageDemo.exe ImageDemo.cs ..\hpdf.cs
ImageDemo.exe

csc /out:JPFontDemo.exe JPFontDemo.cs ..\hpdf.cs
JPFontDemo.exe

csc /out:LineDemo.exe LineDemo.cs ..\hpdf.cs
LineDemo.exe

csc /out:OutlineDemo.exe OutlineDemo.cs ..\hpdf.cs
OutlineDemo.exe

csc /out:Encryption.exe Encryption.cs ..\hpdf.cs
Encryption.exe

csc /out:Permission.exe Permission.cs ..\hpdf.cs
Permission.exe

csc /out:RawImageDemo.exe RawImageDemo.cs ..\hpdf.cs
RawImageDemo.exe

csc /out:TextDemo.exe TextDemo.cs ..\hpdf.cs
TextDemo.exe
 

Because I do not know the Visual studio well, I do not explain usage on Visual Studio here.  

NOTE:
libhpdf.dll is required to run the program which uses C# interface for libharu.
I tested this interface only in Microsoft .NET Framework SDK 1.1.
