 Included is a UI tool to inspect PDFs: the PDFExplorer (internal version of the [[PDFtalkSnooper]] application).
-===== What's new =====
+===== Related projects =====
-This is version 2.0 of the library (October 2017). See the [[releaseNotes|release notes]] for details.
+==== Libraries ====
+**[[complexvalues|Values]]** A base library for immutable complex objects facilitating functional programming.
-**Name** The new name is //**PDFtalk**//. The first version was called //PDF4Smalltalk//. The namespace changed from ''PDF'' to ''PDFtalk'' and the domain "pdftalk.de" provides a home with a wiki dedicated to the library: [[https://wiki.pdftalk.de|wiki.pdftalk.de]].
+**[[RDF]]** The implementation of the W3C Recommendation [[https://www.w3.org/TR/2014/REC-rdf-syntax-grammar-20140225/|RDF 1.1 XML Syntax]].
-**Typing** The heard of the “PDF engine” is the [[newtyping|typing system]] which allows the assignment of Smalltalk classes to raw PDF objects. The new version has a redesigned type system where PDF types are properly modeled independent from the Smalltalk class hierarchy. This allows to rename classes freely (i.e. adding prefixes) without affecting PDF types. Also, boxing of some simple objects like "null" and booleans is not necessary anymore. Instead, existing classes are declared as PDF types.
+**[[PostScript]]** Implementation of the PostScript Level 3 language (without graphics or rendering).
-**[[PDFtalk4Gemstone|PDFtalk for Gemstone]]** The new release was triggered by a contract to port the library to Gemstone (thanks to HTS and Bob Nemec). A talk about this was held at ESUG 2017: "PDFtalk for Gemstone" (slides are [[https://www.slideshare.net/esug/pdftalk-for-gemstone|here]]).
+**[[CMap]]** Font encodings for Type 0 fonts (large fonts for Japanese, Chinese, Korean...)
+==== Gemstone ====
-**[[GemstoneFileout|Gemstone Fileout]]** A VisualWorks to Gemstone translation tool. This tool, with project specific code transformation declarations, creates a Gemstone filein. Used to create the Gemstone PDFtalkLibrary from the Values package and PDFtalk bundle.
+**[[PDFtalk4Gemstone|PDFtalk for Gemstone]]** The port of the library to Gemstone Smalltalk. A talk about this was held at ESUG 2017: "PDFtalk for Gemstone" (slides are [[https://www.slideshare.net/esug/pdftalk-for-gemstone|here]]).
-Both new projects are open source with MIT licence.
+**[[SmalltalkTransform|Smalltalk Transform Project]]** A translation tool for VisualWorks to generate Smalltalk for other dialects. Project specific code transformation declarations are used to generate a filein for the target dialect. This is the next more general version of the [[GemstoneFileout|Gemstone Fileout]] project.
-===== Get started =====
-The slides {{pdf:esug2011_slides_pdf_in_smalltalk.pdf|"PDF in Smalltalk"}} (a talk at [[http://www.esug.org/|ESUG]] 2011), give an overview of what this project is about.
+The projects above are open source with MIT licence.
-Load the **{PDFtalk Project}** bundle from the [[storeaccess|Cincom Public Store]] into your [[http://www.cincomsmalltalk.com/main/products/visualworks/|VisualWorks]] image.
+==== Tools ====
-Try the [[examples|demos and examples]].
+**[[PDFtalkSnooper|Snooper]]** Stand-alone UI tool to inspect PDFs. This is the packaged version of the internal tool.
-Read the [[documentation]].
-To get the latest news and to participate in discussions, subscribe to the [[http://www.freelists.org/list/pdf4st|mailing list]].
