PdfReader for purePDF

Alessandro Crugnola actionscript , , , , ,

Recently I’ve update purepdf adding PdReader.

Using PdfReader an existing pdf document can be opened and parsed. Later I will also port the PdfStamper which will allow to modify existing pdf documents.
Currently I’ve posted 3 simple examples about the PdfReader:
  1. Extract bookmarks
  2. Extract text
  3. Extract images
  4. ExtractTextPDF.air (air application): browse for local pdf documents and display pages contents
Currently the reader has some limitations (such as it cannot open crypted documents) and it’s not fast enough, but I hope to optimize it in the future.

purePDF, a complete actionscript PDF library

Alessandro Crugnola actionscript, purePDF , , , , ,

PurePDF is a complete library for creating PDF documents using actionscript 3 ( targeted for flash player 10 ).
The project is actually hosted on google code.

This is is a porting I’ve made of the famous java iText library ( version 4.2 ) by Bruno Lowagie into pure actionscript 3.0 (with some little modifications).
iText ( and purePDF ) has tons of features for create and manipulate pdf documents. A quick list of the features actually implemented into purepdf:

  • pdf viewers display options
  • alpha transparency, blend modes
  • layers
  • arabic RTL writing
  • support for pdf text rendering ( example )
  • tables ( nested tables, page split tables, table with images, etc…)
  • slide show ( page transitions )
  • annotations, comments, file annotations
  • patterns, shadings patterns (linear and gradient), spot colors, rgb color and cmyk color
  • linear and radial gradients with alpha ( example or example 2 )
  • forms (user input forms, textfields, combo box, list, checkbox)
  • paragraphs, phrases, chunks for text manipulation, chapters, lists…
  • images (jpeg, png, animated gif, tif, bitmapdata ) and image patterns
  • basic and advanced paths
  • afm, otf, pfm, ttc and ttf fonts (embedded and not embedded)
  • metadata, page header and footers
  • external, internal links
  • barcodes creation ( ean-ucc 13, ucc-12, ean-ucc-8, upc-e, pdf 417, ean supplements) ( example )
  • unicode, cjk fonts and text
  • file attachments
  • javascript ( example )
  • multi column text
  • Embedded movies ( example )
  • Vertical text ( see this example )
  • and many other features…

You can take a look at this PDF document (self generated using actionscript reflection) with the purePDF APIs.

Other actionscript libraries I’ve used for this project are: fzlib, as3corelib, ashashmap, alchemy, as3-commons.

You can both download the library from source code and compile it yourself ( see at the Installation guide ) or download the precompiled swc files from the project’s download section.

Moreover there are actually a lot of examples to explain all the library features and for a quick guide. You can find them listed and updated here. In General refers to the project wiki for all the updated examples/howtos and the project updates.

update: here you can find the updated online api documentation
