wxPdfDocument

8.02-0ubuntu2

What is wxPdfDocument?

wxPdfDocument is a C++ class which allows wxWidgets applications to generate PDF files. The code is a port of FPDF - a free PHP class for generating PDF files - to C++ using the wxWidgets library. wxPdfDocument does not make use of any libraries like PDFlib or ClibPDF which require a fee at least for commercial usage. wxPdfDocument is published under the wxWidgets (formerly wxWindows) license. This means you may use it for any kind of usage and modify it to suit your needs.

wxPdfDocument offers all advantages of FPDF. Several add-on PHP scripts found on the FPDF web site are incorporated into wxPdfDocument. The main features are:

The class can produce documents in many languages other than the Western European ones: Central European, Cyrillic, Greek, Baltic and Thai, provided you own TrueType or Type1 fonts with the desired character set. In the Unicode build Chinese, Japanese and Korean are supported, too.

A Reference Manual showing all available methods in alphabetical order is provided. A sample application including more than 20 examples demonstrates the different features. A separate detailed description is available for the MakeFont Utility. The chapter Styling text using a simple markup language describes the supported tags of the simple XML markup language used by the method wxPdfDocument::WriteXml.

wxPdfDocument is hosted as a component of wxCode. For any remark, question or problem, you can leave a message on the appropriate wxCode tracker accessible from the wxCode support page. Or you can send a mail to me directly.

Version history

Todo:
Although all features were thoroughly tested individually, not all possible combinations were verified to function properly. This means: wxPdfDocument still needs intensive testing. If you find bugs please report them to the author!
0.8.0 - December 2006
Added features:
  • support for external templates: pages of existing PDF documents may be imported and used as templates
  • font subsetting for TrueType and TrueType Unicode fonts, often resulting in much smaller PDF file sizes
  • support for using and embedding OpenType Unicode fonts
  • enhanced support for password based encryption, encryption key length freely definable between 40 and 128 bits (Attention: Adobe Reader supports only keys with 40 or 128 bits.)
  • support for AES encryption (additional standard encryption method in PDF version 1.6 and above)

wxPdfDocument is compatible with wxWidgets version 2.8.0 as well as with version 2.6.x.

As an add-on preprocessed font files for the free DejaVu fonts (version 2.12) are provided in the file release wxPdfDocument Add-Ons.

Attention: For supporting font subsetting for ordinary non-Unicode TrueType fonts the format of the font definition files has been extended. Font definition files created with prior versions of the MakeFont Utility are still usable, but do not support font subsetting. It is recommended to regenerate own font definition files. Unfortunately common AFM font metric files do not contain glyph information which is required by the MakeFont Utility to create the character-to-glyph mapping. Therefore the utility ttf2ufm had to be changed. The modified version including a Windows executable is available in the file release wxPdfDocument Add-Ons.

0.7.6 - October 2006
Added features (thanks to Stuart Smith):
  • setting/getting the default path used for loading font files
  • getting the description of the current font
  • loading images from a wxInputStream (in addition to loading from file or wxImage)

Attention: The structure of the font definition files has changed due to the addition of the font attribute xHeight. It is necessary to regenerate own font definition files using the MakeFont Utility. To support the xHeight attribute the utility ttf2ufm had to be changed.

wxPdfDocument is now compatible with wxWidgets version 2.7.1 and above as well as with version 2.6.x.
