SYNOPSIS
use Photonic::Geometry::FromImage2D;
my $g=Photonic::Geometry::FromImage2D->new(path=>$filename);
my $path=$g->path;
my $B=$g->B;
my $G=$g->G;
DESCRIPTION
Creates a geometry object to be used in a Homogeneization calculation using as input a monochromatic 2D image.
METHODS
new(path=>$p, L=>$L, inverted=>$i)
Creates a new H::G::F object
$p is the filename of a 2D monochromatic image with white regions corresponding to the B region and black corresponding to A, unless inverted. Its size must be odd along both directions.
$L is the size of the unit cell along the cartesian axes. By default, it is the number of pixels.
ATTRIBUTES
path
The filename containing the image
inverted
Controls whether the characteristic function ought to be inverted: 1 means invert, 0 don't invert. Default: 0
