Free postscript reader software for linux

PyScript project is a python module for producing high quality postscript graphics. Rather than use a GUI to draw a picture, the picture is programmed using python and the PyScript objects.
Main features:
- All scripting is done in python, which is a high level, easy to learn, well-developed scripting language.
- All the objects can be translated, scaled, rotated, ... in fact any affine transformation.
- Plain text is automatically kerned.
- You can place arbitrary LaTeX expressions on your figures.
- You can create your own figure objects, and develop a library of figure primitives.
- Output is publication quality.

Stream::Reader is a stream reader Perl class.

SYNOPSIS

# Input stream can be reference to TYPEGLOB or SCALAR, output stream
# can be the same types or undefined

# Constructor
$stream = Stream::Reader->new( *IN,
{ Limit => $limit, BuffSize => $buffsize, Mode => UB } );

# Reading all before delimiter beginning from current position.
# Delimiter is SCALAR or reference to array with many SCALARs.
# Returns true value on succesfull matching or if end of stream
# expected at first time
$bool = $stream->readto( $delimiter,
{ Out => *OUT, Limit => $limit, Mode => AIE } );

# Reading fixed number of chars beginning from current position.
# Returns true value if was readed number of chars more then zero or
# end of stream was not expected yet
$bool = $stream->readsome( $limit, { Out => *OUT, Mode => A } );

# Mode is string, what can contains:
# U - modificator for constructor. disable utf-8 checking
# B - modificator for constructor. enable second buffer for speed up
# case insensitive search
# A - modificator for readto() and readsome(). appending data to
# output stream, if stream is SCALAR
# I - modificator for readto(). enable case insensitive search
# E - modificator for readto(). at end of input stream alltimes
# returns false value

$number = $stream->{Total}; # total number of readed chars
$number = $stream->{Readed}; # number of readed chars at last
# operation (without matched string
# length at readto() method)
$number = $stream->{Stored}; # number of succesfully stored chars
# at last operation
$string = $stream->{Match}; # matched string at last operation
# (actually for readto() only)
$bool = $stream->{Error}; # error status. true on error

METHODS

OBJ = Stream::Reader->new( INPUT, { ... Params ... } )

The constructor method instantiates a new Stream::Reader object.

INPUT - is a reference to file stream, opened for reading, or reference to defined string. This is an obligatory parameter.

Params (all optionaly):

Limit - limit size of input stream data in characters. If this parameter is absent, not defined or less then zero, then all data from input stream will be available for reading.

BuffSize - size of buffer in characters. If this parameter is absent, not defined or less then zero, then will be used default buffer size 32768 characters.

Mode - is string with letters-modificators:

B - use second buffer. Can really speed up search in case insensitive mode.
U - disable UTF-8 data check in UTF-8 mode. Use this flag if you are absolutely sure, that your UTF-8 data is valid.

RESULT = OBJ->readto( DELIMITER, { ... Params ... } )

This method reads all data from input stream before first found delimiter, beginning from current position.

RESULT - boolean value. True value if successfuly found delimeter or and of input stream has expected at first time. False value otherwise, or in case of reading error.

DELIMETER - is a string-delimeter or reference to array with many delimeters. This is an obligatory parameter and must be defined.

Remember! In case of many delimiters, left delimiter alltimes have more priority then right!

Params (all optionaly):

Out - is a reference to file stream, opened for writing, or reference to string. If this parameter is absent then data will not stored.
Limit - size in characters. Defines, the maximum number of characters that must be stored in Out. If this paramter is absent, not defined or less then zero, then this method will be trying to store all readed data.
Mode - is string with letters-modificators:
A - appendig data to Out if Out is a reference to string.
I - search in case insensitive mode.
E - at the end of input stream returns only false value. Without this modificator, if end of stream expected at first time, then will be returned true value.

RESULT = OBJ->readsome( LIMIT, { ... Params ... } )
This method reads fixed number of characters from input stream beginning from current position.

RESULT - boolean value. True value, if any characters were read or end of input stream is not expected yet. False value otherwise, or in case of reading error.

LIMIT - limit size in characters, how many it is necessary to read. If this parameter is absent, not defined or less then zero, then will be read all available data from input stream.

Params (all optionaly):

Out - the same as in readto() method.
Mode - is string with letters-modificators:
A - the same as in readto() method.

Statistics:

OBJ->{Total} - total number of readed characters. Warning! This module using block reading and real position in stream is different.
OBJ->{Readed} - number of readed characters at last operation (without matched string length at readto() method).
OBJ->{Stored} - number of succesfully stored chars at last operation
OBJ->{Match} - matched string at last operation (actually for readto() only)
OBJ->{Error} - boolen error status. At any reading erorrs all operations will be stopes and this flag turned to true value.

dotBook reader is a reader for HTML books in .jar and .zip files.

The dotBook application will be a book reader that can download, display and cache books in a special JAR file format.

The format will allow digital signatures with PGP and allow books to have chapters and paragraphs that can be found conveniently from within the application but will link sources outside books by opening the default web browser. Book pages will be HTML pages with some restrictions.

Design Goals

The goal is to have an XML descriptor format to be stored outside the book (JAR file) and an XML content format to be stored inside the JAR file. A compound format that allows to combine descriptor, JAR file and signatures in a single file is being considered. Reading the descriptor should be very easy and not require to read the JAR file, so the JAR file will possibly be compressed and appended to the uncompressed descriptor.

The book layout will honor CSS PrintLayouts.

The XML content will allow for imprints following an independent specification for XML imprints, factored out from the esp.nongnu.org project.

The dotBook editor will allow to edit a limited subset of the MediaWiki syntax and a subset of HTML.

The format is intended to be useful on e-Paper devices that can hibernate between turning pages. A sequential page order will be encouraged, while still allowing to set anchors and links inside pages. Animated content will be discouraged: It will probably only be animated on user request. That means all animated images will be replaced by empty boxes with the text "Animation : [play]" inside, if no still image is provided to take the place.

RTF::Reader is a base class for building RTF-processing modules.

Gives you a simple toolset for doing what you want with RTF

THIS MODULE IS AT BEST BETA, AT WORST, STILL IN PLANNING. The interface may change, the docs are almost certainly slighty out of date.... The latest version of all this is in CVS - use that instead where possible. Details at http://rtf.perl.org/...

RTF::Reader is a base-class that opens up an API for you to use to convert RTF into other formats. The basic model is that you have contexts which represent places in an RTF document, for which you can define what action is taken when different types of RTF constructs are encountered.

Before starting, you should also read RTF::Reader::Context to get a better idea of how to do this.

CAD::Drawing::IO::PostScript is a Perl module with PostScript output methods.

I would like this module to both load and save PostScript vector graphics, but I have not yet found a suitable PostScript parsing package.

This module should be considered pre-ALPHA and untested. Some features rely on the authors hacks to PostScript::Simple, which may or may not have been incorporated into the CPAN distribution of PostScript::Simple. For bleeding-edge code, see http://ericwilhelm.homeip.net.

Requisite Plug-in Functions

See CAD::Drawing::IO for a description of the plug-in architecture.

check_type

Returns true if $type is "circ" or $filename is a directory containing a ".circ" file.

$fact = check_type($filename, $type);

Methods

load

load();

save

$drw->save($filename, %opts);

PostScript::Simple::setpscolor

PostScript::Simple::setpscolor();
