hpdf.js

=======

Create PDFs in your browser (port of libharu)

[See the demo page](http://manuels.github.com/hpdf.js/)

Why?

====

Because other projects with the same goal lack a lot of features (e.g. custom fonts).

Features

========

- Custom Fonts (Type1 and TTF)

- PNG, JPG and RAW images

- Password encryption

- Text and Link Annotations

- Outlines

- Drawing function (lines, cycles etc.)

- Encoding support

How to use

==========

Include `hpdf.js` or `hpdf.min.js` in your HTML file and [see examples](http://manuels.github.com/hpdf.js/) or [libharu API reference](https://github.com/libharu/libharu/wiki)

API naming convention

=====================

- Function names are like their [libharu API](https://github.com/libharu/libharu/wiki) pendants but object-oriented and their first letter is lowercase.

```

    // javascript code                           // C code

    var pdf = new HPDF();                        HPDF_Doc pdf = HPDF_New (error_handler, NULL);

    var page = pdf.addPage();                    HPDF_Page page = HPDF_AddPage(pdf);

    pdf.free();                                  HPDF_Free(pdf);

```

- ``Get`` in the function name is ommitted and ``Set`` is kept

```

    // javascript code                           // C code

    var width = page.width();                    HPDF_REAL width = HPDF_Page_GetWidth(page);

    page.setLineWidth(5);                        HPDF_Page_SetLineWidth(page, 5);

```

- Use ``undefined`` in Javascript where you would use ``NULL`` in C

```

    // javascript code                           // C code

    var root = pdf.createOutline(undefined,      root = HPDF_CreateOutline (pdf, NULL, "OutlineRoot", NULL);

       "OutlineRoot", undefined);

```

- Use strings (case irrelevant) in Javascript where you would use constants in C

```

    // javascript code                           // C code

    page.setSize('B5', 'landscape');             HPDF_Page_SetSize(page, HPDF_PAGE_SIZE_B5, HPDF_PAGE_LANDSCAPE);

```

- Tailing ``NULL``/``undefined`` can be ommitted

```

    // javascript code                           // C code

    var font = pdf.font('Helvetica');            HPDF_Font font = HPDF_PDF_GetFont(pdf, 'Helvetica', NULL);

```

- Instead of calling a error handler in C, an ``Exception`` is thrown in Javascript

Dependencies

============

None. You just need [emscripten](https://github.com/kripken/emscripten) and [CoffeeScript](http://www.coffeescript.org/) if you want to help developing hpdf.js

How to compile (for devs only)

===============================

1. Configure libhaku

``cmake ./libharu``

1. Configure libpng

``cd ./libpng; cmake .; cd ..``

2. Compile hpdf.js

``./compile.sh``

(You might want to change some paths in this bash script!)
