NAME

Imager::Search::Driver - Locate an image inside another image

SYNOPSIS

# Create the search
my $search = Imager::Search::Driver->new(
    driver => 'HTML8',
    big    => $large_imager_object,
    small  => $small_imager_object,
);

# Run the search
my $found = $search->find_first;

# Handle the result
print "Found at row " . $found->top . " and column " . $found->left;

DESCRIPTION

THIS MODULE IS CONSIDERED EXPERIMENTAL AND SUBJECT TO CHANGE

This module is designed to solve a conceptually simple problem.

Given two images (we'll call them Big and Small), where Small is contained within Big zero or more times, determine the pixel locations of Small within Big.

For example, given a screen shot or a rendered webpage, locate the position of a known icon or picture within the larger image.

The intent is to provide functionality for use in various testing scenarios, or desktop gui automation, and so on.

METHODS

new

my $driver = Imager::Search::Driver->new;

The new constructor takes a new search driver object.

Returns a new Imager::Search::Driver object, or croaks on error.

find

The find method compiles the search and target images in memory, and executes a single search, returning the position of the first match as a Imager::Match::Occurance object.

find_first

The find_first compiles the search and target images in memory, and executes a single search, returning the position of the first match as a Imager::Match::Occurance object.
