 Included is a UI tool to inspect PDFs: the PDFExplorer (internal version of the [[PDFtalkSnooper]] application).
-===== What's new =====
+===== Get started =====
-This is version 2.0 of the library (October 2017). See the [[releaseNotes|release notes]] for details.
+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.
+Load the **{PDFtalk Project}** bundle from the [[storeaccess|Cincom Public Store]] into your [[http://www.cincomsmalltalk.com/main/products/visualworks/|VisualWorks]] image.
-**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]].
+Copy the original {{pdf:pdf32000_2008.pdf|PDF specification (ISO standard PDF 32000-1:2008)}} to your image directory. This PDF is needed for some examples and tests.
-**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.
+Note 1: The old version of the library is still in the store under the name {PDF Development}. Don't load this.
-**[[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]]).
+Note 2: The library uses the ''Values'' package. There has been an incompatible change in version 3. Unfortunately, the old version is in the contribution of VisualWorks up to version 8.3.2. If the old version is loaded, you get errors about ''OrderedDictionary''. This class has been renamed to ''Valuemap'' in the new version. If this error hits you (I tried to prevent this by improving the prerequisites), please load ''Values'' version 3.x first.
-**[[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.
+Try the [[examples|demos and examples]].
-Both new projects are open source with MIT licence.
+Read the [[documentation]].
