!pdf 0.72c dd 980525

ReadMe1st
=========
!pdf is based on the program xpdf from Derek Noonburg . 
The original xpdf README file is in this archive, as xpdf_docs.README. The
directory xdpf_docs contains the original documents as supplied by Derek.

I have not included the source to !pdf because I am stil developing it.
You can have the orginal source package as distributed by the 
author (Derek Noonburg mailto:derekn@ece.cmu.edu). To obtain the original source
you should look at:

WWW: http://www.aimnet.com/~derekn/xpdf/

Thanks are due to Derek for permission to distribute !Pdf.

!Pdf
====

!Pdf is a RISC OS port of the pdf reader for X which has been written by
Derek Noonburg. !Pdf reads a Adobe(R) Portable Document Format (PDF) file
and displays this in a window.

!pdf has been tested on:
Archimedes 310  4 mb, RiscOs 3.1, FPA
SA RiscPC      20 mb, RiscOs 3.7

Resources
========
To use !Pdf you need the following resources:
- Acorn toolbox modules.
- 2 megabyte of ram. You can alter the wimpslot but !pdf may hang because
  of memory shortage by large documents.
- Patience, the rendering of a page will take a long time. Even just a page
  with text takes on a SA 2 - 3 seconds.

Filetype
========
The official filetype for Adobe(R) pdf files is &ADF.

Features
========
Altough !pdf is based on version 0.7a of xpdf it does not support all the
features of xpdf. The following features are supported by !pdf:
- Zoom
- Save as drawfile
- links (including URL's)
- Printing
- Rotated text
- encrypting

The following features are not supported:
- clipping

Known bugs
==========
- Calculating alternate fontsizes is not quite correct
- There is a difference in character mapping between my Archimedes and RiscPC

Planned features
================
There are no planned new features. I want to spend time  enhancing the
current features eg. better printing, clipping, etc.

Bug reports
===========
For bugs regarding !pdf you can email me. If those bugs relate to xpdf I will
forward them to Derek Noonburg. Do not just say this or that does not work
but also what pdf file (location only www or ftp address only please) and a
small description of it (eg what page, appearence, chrash or looks, etc) and
the !Pdf version please.

Please bear in mind that I do not have much time to enhance !pdf (this
version (again) waited 3 months before I finalised it) but I will work on it
from time to time.
