NAME

PDF::Builder - Facilitates the creation and modification of PDF files

SYNOPSIS

    use PDF::Builder;

    # Create a blank PDF file
    $pdf = PDF::Builder->new();

    # Open an existing PDF file
    $pdf = PDF::Builder->open('some.pdf');

    # Add a blank page
    $page = $pdf->page();

    # Retrieve an existing page
    $page = $pdf->openpage($page_number);

    # Set the page size
    $page->mediabox('Letter');

    # Add a built-in font to the PDF
    $font = $pdf->corefont('Helvetica-Bold');

    # Add an external TTF font to the PDF
    $font = $pdf->ttfont('/path/to/font.ttf');

    # Add some text to the page
    $text = $page->text();
    $text->font($font, 20);
    $text->translate(200, 700);
    $text->text('Hello World!');

    # Save the PDF
    $pdf->saveas('/path/to/new.pdf');

A NOTE ON STRINGS (CHARACTER TEXT)

Perl (and PDF::Builder) internally use strings which are either ISO-8859-1 or UTF-8 encoded (there is an internal flag marking the string as UTF-8 or not). If you work strictly in ASCII, with no Latin-1, CP-1252, or other non-ASCII characters in your text, you should be OK in not doing anything special about your string encoding. However, any string containing non-ASCII characters (0x80 or higher) should for safety be converted to the Perl UTF-8 internal representation, via $string = Encode::decode(MY_ENCODING, $input);. MY_ENCODING would be a string like 'latin1', 'cp-1252', 'utf8', etc. Similar capabilities are available for declaring a file to be in a certain encoding.

If you are using Latin-1 (ISO-8859-1) text, or CP-1252 without Microsoft's "Smart Quotes" and extended accented letters, you can probably get away with leaving the string in the default ISO-8859-1 encoding. However, you should still get into the habit of converting to UTF-8 (including if the text is already UTF-8 -- Perl won't know that). Needless to say, anything using a non-Latin alphabet will need to be properly converted before Perl (and PDF::Builder) can use it. Any developer writing a Perl application to accept user input (including from files), and feed it to PDF::Builder, should be aware of what encoding the end user is using for their input. Don't assume that any file is a given encoding! Ask the user what it is, an be prepared for mistakes -- CP-1252 is so widespread that many people think it is identical to Latin-1 (it isn't).

By the way, it is recommended that you be using at least Perl 5.10 if you are going to be using any non-ASCII characters. Perl 5.8 may be a little unpredictable in handling such text.

HISTORY

PDF::API2 was originally written by Alfred Reibenschuh, derived from PDF::API. In 2009, Otto Hirr started the PDF::API3 fork, but it never went anywhere. In 2011, maintenance was taken over by Steve Simms. In 2017, PDF::Builder was forked by Phil M. Perry, who desired a more aggressive schedule of new features and bug fixes than Simms was providing.

At Simms's request, the name of the new offering was changed from PDF::API4 to PDF::Builder, to reduce the chance of confusion due to parallel development. Perry's intent is to keep all internal methods as upwardly compatible with PDF::API2 as possible, although it is likely that there will be some drift (incompatibilities) over time. At least initially, any program written based on PDF::API2 should be convertable to PDF::Builder simply by changing "API2" anywhere it occurs to "Builder". See the KNOWN_INCOMP known incompatibilities file for further information.

GENERIC METHODS

$pdf = PDF::Builder->new(%options)

Creates a new PDF object. If you will be saving it as a file and already know the filename, you can give the '-file' option to minimize possible memory requirements later on. The '-compress' option can be given to specify stream compression: default is 'flate', 'none' is no compression.

Example:

    $pdf = PDF::Builder->new();
    ...
    print $pdf->stringify();

    $pdf = PDF::Builder->new(-compress => 'none');
    # equivalent to $pdf->{'forcecompress'} = 'none'; (or older, 0)

    $pdf = PDF::Builder->new();
    ...
    $pdf->saveas('our/new.pdf');

    $pdf = PDF::Builder->new(-file => 'our/new.pdf');
    ...
    $pdf->save();
$pdf = PDF::Builder->open($pdf_file, %options)
$pdf = PDF::Builder->open($pdf_file)

Opens an existing PDF file. See new() for options.

Example:

    $pdf = PDF::Builder->open('our/old.pdf');
    ...
    $pdf->saveas('our/new.pdf');

    $pdf = PDF::Builder->open('our/to/be/updated.pdf');
    ...
    $pdf->update();
$pdf = PDF::Builder->open_scalar($pdf_string, %options)
$pdf = PDF::Builder->open_scalar($pdf_string)

Opens a PDF contained in a string. See new() for options.

Example:

    # Read a PDF into a string, for the purpose of demonstration
    open $fh, 'our/old.pdf' or die $@;
    undef $/;  # Read the whole file at once
    $pdf_string = <$fh>;

    $pdf = PDF::Builder->open_scalar($pdf_string);
    ...
    $pdf->saveas('our/new.pdf');

Note: Old name openScalar is deprecated! Convert your code to use open_scalar instead.

    EOT

    $xml = $pdf->xmpMetadata($xml);
    print "PDF metadata now reads: $xml\n";
$pdf->pageLabel($index, $options)

Sets page label options.

Supported Options:

-style

Roman, roman, decimal, Alpha or alpha.

-start

Restart numbering at given number.

-prefix

Text prefix for numbering.

Example:

    # Start with Roman Numerals
    $pdf->pageLabel(0, {
        -style => 'roman',
    });

    # Switch to Arabic
    $pdf->pageLabel(4, {
        -style => 'decimal',
    });

    # Numbering for Appendix A
    $pdf->pageLabel(32, {
        -start => 1,
        -prefix => 'A-'
    });

    # Numbering for Appendix B
    $pdf->pageLabel( 36, {
        -start => 1,
        -prefix => 'B-'
    });

    # Numbering for the Index
    $pdf->pageLabel(40, {
        -style => 'Roman'
        -start => 1,
        -prefix => 'Index '
    });
$pdf->finishobjects(@objects)

Force objects to be written to file if possible.

Example:

    $pdf = PDF::Builder->new(-file => 'our/new.pdf');
    ...
    $pdf->finishobjects($page, $gfx, $txt);
    ...
    $pdf->save();
$pdf->update()

Saves a previously opened document.

Example:

    $pdf = PDF::Builder->open('our/to/be/updated.pdf');
    ...
    $pdf->update();
$pdf->saveas($file)

Save the document to $file and remove the object structure from memory.

Example:

    $pdf = PDF::Builder->new();
    ...
    $pdf->saveas('our/new.pdf');
$string = $pdf->stringify()

Return the document as a string and remove the object structure from memory.

Example:

    $pdf = PDF::Builder->new();
    ...
    print $pdf->stringify();
$pdf->end()

Remove the object structure from memory. PDF::Builder contains circular references, so this call is necessary in long-running processes to keep from running out of memory.

This will be called automatically when you save or stringify a PDF. You should only need to call it explicitly if you are reading PDF files and not writing them.

PAGE METHODS

$page = $pdf->page()
$page = $pdf->page($page_number)

Returns a new page object. By default, the page is added to the end of the document. If you include an existing page number, the new page will be inserted in that position, pushing existing pages back.

If $page_number is -1, the new page is inserted as the second-last page; if $page_number is 0, the new page is inserted as the last page.

Example:

    $pdf = PDF::Builder->new();

    # Add a page.  This becomes page 1.
    $page = $pdf->page();

    # Add a new first page.  $page becomes page 2.
    $another_page = $pdf->page(1);
$page = $pdf->openpage($page_number)

Returns the PDF::Builder::Page object of page $page_number.

If $page_number is 0 or -1, it will return the last page in the document.

Example:

    $pdf = PDF::Builder->open('our/99page.pdf');
    $page = $pdf->openpage(1);   # returns the first page
    $page = $pdf->openpage(99);  # returns the last page
    $page = $pdf->openpage(-1);  # returns the last page
    $page = $pdf->openpage(999); # returns undef
$xoform = $pdf->importPageIntoForm($source_pdf, $source_page_number)

Returns a Form XObject created by extracting the specified page from $source_pdf.

This is useful if you want to transpose the imported page somewhat differently onto a page (e.g. two-up, four-up, etc.).

If $source_page_number is 0 or -1, it will return the last page in the document.

Example:

    $pdf = PDF::Builder->new();
    $old = PDF::Builder->open('our/old.pdf');
    $page = $pdf->page();
    $gfx = $page->gfx();

    # Import Page 2 from the old PDF
    $xo = $pdf->importPageIntoForm($old, 2);

    # Add it to the new PDF's first page at 1/2 scale
    $gfx->formimage($xo, 0, 0, 0.5);

    $pdf->saveas('our/new.pdf');

Note: You can only import a page from an existing PDF file.

$page = $pdf->import_page($source_pdf, $source_page_number, $target_page_number)

Imports a page from $source_pdf and adds it to the specified position in $pdf.

If $source_page_number or $target_page_number is 0 (the default) or -1, the last page in the document is used.

Note: If you pass a page object instead of a page number for $target_page_number, the contents of the page will be merged into the existing page.

Example:

    $pdf = PDF::Builder->new();
    $old = PDF::Builder->open('our/old.pdf');

    # Add page 2 from the old PDF as page 1 of the new PDF
    $page = $pdf->import_page($old, 2);

    $pdf->saveas('our/new.pdf');

Note: You can only import a page from an existing PDF file.

Note: Old name importpage is deprecated! Convert your code to use import_page instead.

$count = $pdf->pages()

Returns the number of pages in the document.

$pdf->mediabox($name)
$pdf->mediabox($w,$h)
$pdf->mediabox($llx,$lly, $urx,$ury)

Sets the global mediabox.

Example:

    $pdf = PDF::Builder->new();
    $pdf->mediabox('A4');
    ...
    $pdf->saveas('our/new.pdf');

    $pdf = PDF::Builder->new();
    $pdf->mediabox(595, 842);
    ...
    $pdf->saveas('our/new.pdf');

    $pdf = PDF::Builder->new;
    $pdf->mediabox(0, 0, 595, 842);
    ...
    $pdf->saveas('our/new.pdf');
$pdf->cropbox($name)
$pdf->cropbox($w,$h)
$pdf->cropbox($llx,$lly, $urx,$ury)

Sets the global cropbox.

$pdf->bleedbox($name)
$pdf->bleedbox($w,$h)
$pdf->bleedbox($llx,$lly, $urx,$ury)

Sets the global bleedbox.

$pdf->trimbox($name)
$pdf->trimbox($w,$h)
$pdf->trimbox($llx,$lly, $urx,$ury)

Sets the global trimbox.

$pdf->artbox($name)
