Is there code available in the Squeak universe for reading .PDF files? In particular I wish to read a multi-page file produced by a text scanner -- ie probably compressed black-and-white images.
Thanks in advance

There is an overview of PDF writers (not readers) for Seaside here: http://www.seaside.st/documentation/pdfs
The overview points to SPDF, a "low-level, not very complete smalltalk library" here: http://map.squeak.org/package/d8fd5e1a-2bb7-4c99-a77e-f945dfce01eb
I am not aware of any PDF readers, so hopefully someone else can point to something.

Recently, in a Smalltalk new group,
Alejandro Reimondo aleReimondo at smalltalking dot net http://www.aleReimondo.com
announced "a PDF Framework capable to parse PDF files and construct a fine grained object model of text (also unicode), images, lineArt, fonts, colors and other features of each element contained in a PDF document."
I believe this is a product for sale.

In the same news group (comp.lang.smalltalk.dolphin) you can find this message from david at gorisek.com:
This is precisely what we have been doing in our on-line ERP at http://www.e-racuni.com for the last 6 years.
For this purpose I have developed a PDF parser/generator in Smalltalk which allows you to parse any PDF document so that you can add text objects to it. Then you can also merge multiple PDF documents with various forms together into a single document, and then finally you can re-recreate PDF document and send it to the user over the web to be printed using Adobe PDF or FoxIt Reader. If anybody is interested then send me a private e-mail.
...
Interesting! What Smalltalk dialect?
The code is just manipulating strings and streams. So it should work anywhere. We have it in production using Dolphin and VAST. The only non-portable part is the ZLIB library interface but this is taken care by our dialect abstraction layer.

I've written some very general purpose scripts for this purpose. They would allow you to modify and build certain pdfs.
