Free in pdf format software for linux

Common Data Format is a self-describing data abstraction for the storage and manipulation of multidimensional data in a platform- and discipline-independent fashion.
It consists of a scientific data management package (known as the "CDF Library") that allows programmers and application developers to manage and manipulate scalar, vector, and multi-dimensional data arrays.
Enhancements:
- Adds new sets of APIs to allow Standard Interface to interact with zVariables and other CDF-related information.
- Adds MingW and FreeBSD ports.
- Adds support for Intel C++ and Fortran for Linux.
- Adds the ability to create legacy CDF 2.7 files.
- Fixes a bug that prevented directories from having .cdf or .skt extensions.

PdfRipImage is a utility to extract images from PDF documents and convert them to a format of your choice. You can choose to extract whole pages or just the images contained in them.

The program is available as a GNOME graphical version.

PDFMap is a Python library which helps you create of high quality maps in PDF format. Objects of any type (either shapes or images) can be placed on a map and scaled and rotated to reflect their original dimensions and orientation. You can make each object clickable in Adobe Acrobat Reader (e.g., to access a Web-enabled application from which youve extracted the data used to create the map).

It serves successfully in drawing archaelogical objects on cave maps, but as the examples may show you, it can also draw things at a very high scale, e.g. an Europe or World map.

Each map can have an optional rasterized background which can be rotated automatically if it is not North oriented.

PDFMap can automatically draw objects on each map. Objects can be of any type (e.g. City, School, Archaeological objects, whatever you like), and are represented by shapes or images, scaled to the actual objects dimensions and orientation. Each object can also have an associated url which will render the object clickable in tools like Adobe Acrobat Reader (NB : the clickable area is always a rectangle of the actual objects dimensions, not of the representing shapes dimensions), the use of this feature depends entirely on your imagination : draw maps from a database and link back to a web enabled application which manipulates this database is just an example (and an interesting one at that, just
believe me).

PDFMap uses two types of input files :

Configuration files :

Those are used to tell PDFMap which shape or image should represent each type of object, as well as set different parameters for this objects type :pen thickness, colors, minimal and maximal size, etc...

Data files :

Those are used to feed PDFMap with lists of objects to draw. They are generally the result of an ASCII export from your favorite spreadsheet or relational database management system.

The tests/ subdirectory contains sample configuration and data files which are well commented. Read them and run the tests programs to learn how PDFMap works.

PandaLex is the PDF parsing code from Panda, which has been split into its own project to increase its utility.

It is a flex and bison description of the PDF specification, which allows programmers to define callbacks to handle different document elements.

PDF Download is an extension which allows you to choose what to do with a PDF file on a website.

Allows to choose if you want to view a PDF file inside the browser (as PDF or HTML), if you want to view it outside Firefox with your default or custom PDF reader, or if you want to download it!

DateTime::Format::Pg is a Perl module to parse and format PostgreSQL dates and times.

SYNOPSIS

use DateTime::Format::Pg;

my $dt = DateTime::Format::Pg->parse_datetime( 2003-01-16 23:12:01 );

# 2003-01-16T23:12:01+0200
DateTime::Format::Pg->format_datetime($dt);

This module understands the formats used by PostgreSQL for its DATE, TIME, TIMESTAMP, and INTERVAL data types. It can be used to parse these formats in order to create DateTime or DateTime::Duration objects, and it can take a DateTime or DateTime::Duration object and produce a string representing it in a format accepted by PostgreSQL.

CONSTRUCTORS

The following methods can be used to create DateTime::Format::Pg objects.
new( name => value, ... )

Creates a new DateTime::Format::Pg instance. This is generally not required for simple operations. If you wish to use a different parsing style from the default then it is more comfortable to create an object.

my $parser = DateTime::Format::Pg->new()
my $copy = $parser->new( european => 1 );

This method accepts the following options:

european

If european is set to non-zero, dates are assumed to be in european dd/mm/yyyy format. The default is to assume US mm/dd/yyyy format (because this is the default for PostgreSQL).

This option only has an effect if PostgreSQL is set to output dates in the PostgreSQL (DATE only) and SQL (DATE and TIMESTAMP) styles.
Note that you dont have to set this option if the PostgreSQL server has been set to use the ISO format, which is the default.

server_tz

This option can be set to a DateTime::TimeZone object or a string that contains a time zone name.

This value must be set to the same value as the PostgreSQL servers time zone in order to parse TIMESTAMP WITH TIMEZONE values in the PostgreSQL, SQL, and German formats correctly.

Note that you dont have to set this option if the PostgreSQL server has been set to use the ISO format, which is the default.

clone()

This method is provided for those who prefer to explicitly clone via a method called clone().

my $clone = $original->clone();

If called as a class method it will die.

kpdfimagestool is a service menu which allows you to:

- Extract images from a pdf file in jpeg or ppm/pbm format
