NAME ^

Image::Magick::Text::AutoBreak - Utility for auto line break

VERSION ^

This document describes Image::Magick::Text::AutoBreak version 0.02

DESCRIPTION ^

This is a utility class for Image::Magick. With this module, you can easily annotate long strings into multiple lines.

SYNOPSIS ^

    use Image::Magick::Text::AutoBreak;
    
    ### Prepare source
    my $image = Image::Magick->new;
    $image->Read($filename);
    
    ### Constractor
    my $autobreak =
        Image::Magick::Text::AutoBreak->new(
            magick          => $image,
            width           => 231,
            height          => 260,
            x               => 10,
            y               => 80,
            ngCharaForHead => qr/[\\Q,)]`.:;\\E]/, 
            ngCharaForTail => qr/[\\Q([_\\E]/, 
            ngCharaForSepa => qr/[\\Qa-zA-Z0-9'".,!?-\\E]/, 
        );
    
    ### Prepare for annotate before hand
    my @result = $autobreak->prepare(
        text            => $input_string, 
        font            => $font_path, 
        pointsize       => 9,
        fill            => '#000000',
    );
    
    ### Annotate
    $autobreak->annotate();
    
    ### Repeatedly if you need
    $autobreak->annotate(fill => '#0000ff');

INTERFACE ^

new

Constractor. This calls for folloing arguments.

magick

Image::Magick instance.

x

Horizontal position of text area.

y

Vertical position of text area.

width

Width of text area. If not given, allocates [source image width] - x

height

Height of text area. If not given, allocates [source image height] - y

ngCharaForHead

Denied charactors for line head in regular expression

ngCharaForTail

Denied charactors for end-of-line in regular expression

ngCharaForSepa

Denied charactors for separation in regular expression

prepare

This method prepare the annotaion plan. This calls for same arguments as the Image::Magick::QueryFontMetrics does, and the arguments will be thrown at it.

    my @result = $autobreak->prepare(
        text            => $input_string, 
        font            => $font, 
        fill            => '#000000',
        pointsize       => 12,
    );

The arguments will be adopted for default args of annotate thereafter. This method returns the box size of annotation area in array.

annotate

This method is a wrapper for Image::Magick::Annotate. This does Annotate iteratively so that the input strings will be put into multiple line.

This method automatically takes the arguments that prepare has gotten, and you can override each of them.

    $autobreak->annotate(fill => '#ffffff');

The arguments will be thrown at Image::Magick::Annotate. Practically, you should give the arguments that doesn't have influence on the position or size of each line.

    # This doesn't make sense
    $autobreak->annotate(pointsize   => 14);

You can do annotate repeatedly if you need to decorate or something.

    # Draw stroke
    $autobreak->annotate(
        fill            => '#ffffff',
        stroke          => '#ffffff',
        strokewidth     => 6,
    );

    # real part
    $autobreak->annotate();

This method returns the box size of prepared annotation area in array.

getResult

This method returns the box size of prepared annotation area in array.
