DESCRIPTION
This module tries to make it easy to create PDFs by providing a high level interface to a number of existing PDF modules. It aims to "do the right thing" by default, allowing minimal coding to create long PDFs. It includes pagination, headings, paragraph text, images and tables. Although there are a number of other modules to create PDFs with a high-level interface, I found that these each lack certain features (e.g. image insertion, paragraph text). This module tries to include each of those features through another existing module. Also, it is built on PDF::API2, and provides access to that object, so content can also be added directly using that, thereby providing any powerful features required.
METHODS
Returns the PDF::API2
object used to create the PDF.
page
Returns the current PDF page.
add_page
Adds a PDF page and returns it.
Note that when a PDF page is added (either via this method or automatically) the is_new_page flag records that a new page is in use with no content. See that method for more details.
is_new_page
Whether the current page is new with no content. When the heading or text methods are called and this is true, additional top margin is added to account for the height of the text being added. Any other content manually added will not include this margin and will leave the internal new page flag as true.
clear_new_page
Manually clears the is_new_page flag.
orientation
Sets or returns the page orientation (portrait or landscape). Portrait is default.
width
Sets or returns the width. Default is A4.
height
Sets or returns the height. Default is A4.
margin
Sets or returns the page margin. Default 40 pixels.
top_padding
Sets or returns the top padding (additional to the margin). Default 0.
footer
Sets or returns the footer text. Page numbers are added automatically.
font
Sets or returns the font. This is based on PDF::API2 ttfont which returns a TrueType or OpenType font object. By default it assumes the font is available in the exact path truetype/liberation/LiberationSans-Regular.ttf
. A future version may make this more flexible.
fontbold
As font, but a bold font.
logo
The path to a logo to include in the top-right corner of every page (optional).
logo_scaling
The scaling of the logo. For best results a setting of 0.5 is recommended (the default).
logo_padding
The padding below the logo before the text. Defaults to 10 pixels.
heading($text, %options)
Add a heading. If called on a new page, will automatically move the cursor down to account for the heading's height (based on the assumption that one pixel equals one point). Options available are size
, topmargin
and bottommargin
.
text($text, %options)
Add paragraph text. This will automatically paginate. Options available are color
.
table(%options)
Add a table, based on PDF::Table. Options available are data
to pass in the data for the table; all other options are passed to the table method of PDF::Table.
image($file, %options)
Add an image. Options available are scaling
.
content
Return the PDF content.
