11 * What is Haru Free PDF Library?
13 Haru is a free, cross platform, open-sourced software library for generating
14 PDF. It supports the following features.
16 1. Generating PDF files with lines, text, images.
17 2. Outline, text annotation, link annotation.
18 3. Compressing document with deflate-decode.
19 4. Embedding PNG, Jpeg images.
20 5. Embedding Type1 font and TrueType font.
21 6. Creating encrypted PDF files.
22 7. Using various character set (ISO8859-1~16, MSCP1250~8, KOI8-R).
23 8. Supporting CJK fonts and encodings.
25 You can add the feature of PDF creation by using Haru without understanding
26 complicated internal structure of PDF.
29 * The differences from the previous version
32 The biggest differences are that all code is written in C.
33 To our regret, because internal structures changed greatly, The API is not
34 compatible with previous version.
36 However, the new-version has the following advantages compared with the
39 1. Supported shared-library build.
40 A new-version library is able to be built as shared-library.
41 2. The performance has been greatly improved.
42 A new-version library is about 4-15 times faster than a previous version.
43 3. Supported more features.
44 TrueType font, 128 bit encryption, arc function, and so on.
47 * Supporting platforms
49 Haru is written in ANSI-C and should compile easily with any compliant C
51 I inspected Haru in the following environment and make files for these
52 environments are included in a package.
54 1. Cygwin + GCC (Microsoft Windows)
55 2. Cygwin + MinGW (Microsoft Windows)
56 3. MSYS + MinGW (Microsoft Windows)
57 3. Microsoft VC++ (Microsoft Windows)
58 4. Borland C++ (Microsoft Windows)
59 5. GCC (Linux, FreeBSD, NetBSD, Solaris...)
61 Also on platforms except the above, it is easy to build HARU. If you success to build HARU on other platforms, please send makefile to me.
62 In addition, ZLIB and PNGLIB are required when you want to use the features of
63 compression and embedding PNG images. (In the case of Windows, static library
64 files for several compilers are included in the package for WIndows. In the
65 case of most of UNIX, these libraries are usually installed.)
68 * Available development environment
70 Haru can work as both static-library (.a, .lib) and shared-library (.so, .dll).
71 When you use it as static-library, It can be used by C and a C++.
72 But when you use it as shared-library, it can be used by many development
73 languages which support shared library.
74 So far, Haru provides bindings for Ruby, Delphi/Free Pascal and C#.
76 If you write bindings for other programing languages, please notice me!
79 * Runtime environment of programs using Haru
82 No runtime files are required.
85 In Windows, you have to distribute libhpdf.dll with a program. In UNIX you
86 have to distribute libhpdf.so* with a program.
91 In the UNIX environment, there are the cases that libz.so, libpng.so.x are
92 necessary. About this, please refer to the documentation of PNGLIB and ZLIB.
97 Haru is distributed under the ZLIB/LIBPNG License. Because ZLIB/LIBPNG License
98 is one of the freest licenses, You can use Haru for various purposes.
