Bug #103786 for Imager: A bug in flood fill algorithm

Consider this program: use strict; use warnings; use Imager; my $i = Imager-> new( xsize => 100, ysize => 100 ); $i-> box( box => [ 0, 0, 49, 49 ], filled => 1 ); $i-> box( box => [ 50, 50, 99, 99 ], filled => 1 ); my $j = $i-> copy(); $i-> flood_fill( x => 0, y => 0, color => 'red' ); $i-> write( file => '1.png' ); $j-> flood_fill( x => 99, y => 99, color => 'red' ); $j-> write( file => '2.png' ); I would expect 2 images to be the same, but they are different -- an issue with 4 way connectivity, as I understand.

use strict; use warnings; use Imager; my $i = Imager-> new( xsize => 100, ysize => 100 ); $i-> box( box => [ 0, 0, 49, 49 ], filled => 1 ); $i-> box( box => [ 50, 50, 99, 99 ], filled => 1 ); my $j = $i-> copy(); $i-> flood_fill( x => 0, y => 0, color => 'red' ); $i-> write( file => '1.png' ); $j-> flood_fill( x => 99, y => 99, color => 'red' ); $j-> write( file => '2.png' ); __END__
