NAME

Document::Writer::TextLayout - Text layout engine

SYNOPSIS

use Document::Writer;

my $doc = Document::Writer->new(default_color => ...);
my $p = $doc->next_page($width, $height);
$p->add_text_to_page($driver, $font, $text);
...

METHODS

font

Set/Get this text layout's font.

height

Get the height of this text layout. Only useful after layout has been called.

layout

Lay out the text based on the provided attributes.

lines

Set/Get this text layout's 'lines'. This is an arrayref of hashrefs, where each hashref has the following members:

box

The bounding box for the text in this line. This bounding box does not take rotations into consideration.

cb

The bounding box of required for a container that intends to contain the text in this line.

text

The text in this line.

This data structure is the meat of a TextLayout. The multi-line, unwrapped text is broken down into this datastructure based on the width attribute.

slice ($offset, [$size])

Given an offset and an optional size, returns n lines from this layout that come as close to $size without exceeding it. This method is provided to allow incremental rendering of text. For example, if you have a series of containers 80 units high, you might write code like this:

for(my $i = 0; $i < 3; $i++) {
    $lines = $layout->slice($i * 80, 80);
    # render the text
}

text

Set/Get the text to be laid out.

width

Get/Set the width at which the text in this TextLayout should be wrapped.
