.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The main purpose of the \s-1PDF\s0 library is to provide classes and
functions that allow to read and manipulate \s-1PDF\s0 files with perl. \s-1PDF\s0
stands for Portable Document Format and is a format proposed by Adobe.
A full description of this format can be found in the \fBPortable
Document Reference Manual\fR by \fBAdobe Systems Inc.\fR. For more details
about \s-1PDF,\s0 refer to:
.PP
\&\fBhttp://www.adobe.com/\fR
.PP
The main idea is to provide some \*(L"basic\*(R" modules for access 
the information contained in a \s-1PDF\s0 file. Even if at this
moment is in an early development stage, the scripts in the 
example directory show that it is usable.
.PP
\&\fBis_pdf\fR script test a list of files in order divide the \s-1PDF\s0 file
from the non \s-1PDF\s0 using the info provided by the files 
themselves. It doesn't use the \fI.pdf\fR extension, it uses the information
contained in the file.
.PP
\&\fBpdf_version\fR returns the \s-1PDF\s0 level used for writing a file.
.PP
\&\fBpdf_pages\fR gives the number of pages of a \s-1PDF\s0 file.
.PP
\&\fBpagedump.pl\fR prints some information about individual pages in a
PDF-file. Although the information as such are not very useful, it
demontrates well some more complex aspects of the library. Check the
function \fBdoprint\fR in this program on how to handle all possible data
occuring in a \s-1PDF.\s0
.PP
The library is now splitted in 2 section :
.PP
\&\fBPDF::Core\fR that contains the data structure, the constructor and low
level access fuctions;
.PP
\&\fBPDF::Parse\fR all kind of functions to parse the PDF-files and
provide information about the content.
.PP
Check the help-files of these modules for more details.
.SH "Variables"
.IX Header "Variables"
There are 2 variables that can be accessed:
.ie n .IP "\fB\fB$PDF::VERSION\fB\fR" 4
.el .IP "\fB\f(CB$PDF::VERSION\fB\fR" 4
.IX Item "$PDF::VERSION"
Contain the version of the library installed.
.ie n .IP "\fB\fB$PDF::Verbose\fB\fR" 4
.el .IP "\fB\f(CB$PDF::Verbose\fB\fR" 4
.IX Item "$PDF::Verbose"
This variable is false by default. Change the value if you want 
more verbose output messages from library.
