The Big Faceless Graph Library is a Java class library for creating graphs and charts. It is backed by a full 3D engine, allowing you to create shaded 3D pie, bar, and line graphs as GIF, PDF, PNG, or other image formats.
Big Faceless Graph Library features include transparent backgrounds, extensible axes to graph dates, currencies, custom fonts, and spline curve fitting. It is small, fast, and easy to use.
Main features:
- XML and JSP Tag Library interface, for extremely easy integration with web projects
- Very comprehensive API and Tag documentation with dozens of examples
- Embed JavaScript in your tags to easily create powerful rollovers
- Full 3D engine with adjustable light source, produces the most realistic graphs on the market
- Output to PNG, SVG, Macromedia Flash, PDF or java.awt.Image for use in Applets
- Graph Dates, Currencies, Percentages, Numbers and Discrete data out of the box, easily extended for total control over the axes
- Mix Bars, Lines, Candles, Bubbles, all on the same graph
- Add text, lines or custom markers anywhere on the graph, including axes
- Use up to four axes on the one graph, including logarithmic axes
- Plot mathematical functions, data samples and spline curves fitted to data, all on the same graph
- Its fast - plot several 3D graphs a second to PDF
Enhancements:
- Display order of markers on a non-3D graph is now deterministic.
- Markers, images, and labels on bar series appear in the correct place if the order of the bars is changed between series or if the series is part of a stack barseries.
- A label tag can be made into a hyperlink, and now accepts attributes such as href and onmouseover.
- Its possible to cause the GraphServlet to reject requests based on HTTP headers, via the "headercheck.N" init-parameters.

jScraper project provides an easy-to-use interface for parsing HTML text streams. jScraper converts HTML text streams into tokenized object streams revealing the documents contents. This library is ideal for applications which must extract information from machine-generated web pages.
jScraper was initially released as an integrated feature of Lava, a general-purpose class library for Java. By popular demand, jScraper is now distributed in its own bundle.
As an added bonus, the lava.io and lava.string packages are included to make your parsing job easier. These two packages will add a wide variety of parsing routine to your parsing toolbox and will help you parse just about any type of text stream imaginable.
Version restrictions:
- You may download and evaluate jScraper, free of charge, for 15 days.

PDFlib TET (Text Extraction Toolkit) is software for reliably extracting text information from any PDF file. It is available as a library/component and as a command-line tool. TET makes available the text contents of a PDF as Unicode strings or structured XML, plus detailed glyph and font information. With TET you can retrieve the corresponding Unicode values for text in a PDF document, as well as its position on the page.
In addition to low-level text retrieval TET contains advanced content analysis algorithms for determining word boundaries, removing redundant duplicate text (such as shadows and artificial bold). Using the auxiliary pCOS interface you can retrieve arbitrary objects from the PDF, such as metadata, hypertext, etc.
Fully functional evaluation versions of TET including documentation and samples are available from the TET download page for all supported platforms. Purchasing a license and applying the license key will fully enable the evaluation version for production deployment.
With PDFlib TET you can:
- extract text from PDF, e.g. to store it in a database
- implement a search engine for processing PDF
- convert the text content of PDF pages to XML for processing with other tools
- process PDFs based on their contents
Supported PDF Input
PDFlib TET supports all relevant flavors of PDF input:
- all PDF versions up to PDF 1.7 (Acrobat 8)
- all font and encoding types: base 14 fonts, TrueType, PostScript, OpenType, CID fonts
- encrypted PDF with 40- and 128-bit encryption (appropriate permission settings or password required)
Unicode
Although text in PDF is usually not encoded in Unicode, PDFlib TET will normalize the text from a PDF document to Unicode:
- TET converts all text contents to Unicode. In C the text will be returned in the UTF-8 or UTF-16 formats, and as native Unicode strings in all other language bindings.
- Ligatures and other multi-character glyphs will be decomposed into a sequence of their constituent Unicode characters.
- Vendor-specific Unicode assignments (Private Use Area, PUA) are identified, and mapped to characters in the common Unicode area if possible.
- Glyphs without appropriate Unicode mappings are identified as such, and are mapped to a configurable replacement character.
Full CJK Support
TET includes full support for extracting Chinese, Japanese, and Korean text. All predefined CJK CMaps (encodings) are recognized; horizontal and vertical writing modes are supported.
Content Analysis and Word Identification
TET can be used to retrieve low-level glyph information, but also includes advanced algorithms for content analysis:
- Detect word boundaries to retrieve words instead of characters.
- Recombine the parts of hyphenated words.
- Remove duplicate instances of text, e.g. shadow and artificial bold text.
- Recombine paragraphs into reading order.
- Reorder text which is scattered over the page.
- Reconstruct lines of text.
Geometry
TET provides precise metrics for the text, such as the position on the page, glyph widths, text direction. Specific areas on the page can be excluded or included in the text extraction, e.g. to ignore headers and footers or margins.
Version restrictions:
- Unlicensed versions support all features, but will only process PDF documents with up to 10 pages and 1 MB size. Evaluation versions of TET must not be used for production purposes, but only for evaluating the product. Using TET for production purposes requires a valid TET license.
Enhancements:
- repair mode for damaged PDF repairs damaged documents which were rejected by earlier versions of TET
- support for PDF 1.7, the file format of Acrobat 8
- support for AES-encrypted PDF (appropriate password required)
- TET command-line tool: extract the text based on article threads in the document
- updated pCOS interface (the same pCOS as in PDFlib 7)
- Perl language binding
- many new heuristics and workarounds
- Unicode mappings for more documents
- improvements in the Wordfinder
- various bug fixes
- TET Plugin for Acrobat as a free tool and TET technology demo

XContractBridge is a Linux Contract Bridge simulation game.
Main features:
Random deal
- The random deal engine will produce an unlimited variety of hands. The program will bid and play the other three hands with scoring to rubber. Written in the C++ language with direct access to the Xlib primitives for speed and compatibility, the program will also generate specific point count hands in the 0-28 point range.
Animated display
- The program will allow a choice of bidding speed and can also provide simple animation of the play of the cards.
Display options
- All hands may be displayed at any stage, a summary of bids is also available. Additionally each of the other hands may be permanently displayed.
Facilities
- The user may skip to a new deal at any time or replay the existing hand at any stage. The hand may also be revolved.
Deals
- A deal may be quickly saved, with dealer, at any time.
Bidding system
- The program supports the ACOL bidding system with separate toggle settings for conventions for both North South and East West. The settings are retained between sessions.
Conventions
- Stayman, Baron, Jacoby, Gambling, Blackwood and Gerber..
Playing strength
- The program is suitable for casual play and practise. The Bridge engine utilized has been proven on several other platforms (including Colossus Bridge for Windows) and provides a interesting game but is not suitable for strong club players.
Requirements
- A minimum display of 800 by 600 is required. The program has a fixed size window.
Distributions
- The development was aimed at reducing the dependencies and allowing use on the widest variety of Linux platforms. To that end it utilizes the low level Xlib library to directly work with the X Server. It has been tested on Fedora Core, SUSE, Mandrake and others. No installation is required, a single executable file is supplied.
