NAME
FuseBead::From::PNG - Convert PNGs into plans to build a two dimensional
fuse bead replica.
SYNOPSIS
use FuseBead::From::PNG;
my $object = FuseBead::From::PNG;
$object->bead_tally();
DESCRIPTION
Convert a PNG into a block list and plans to build a fuse bead replica
of the PNG. This is for projects that use fuse bead such as perler or
hama.
The RGB values where obtained from Bead List with RGB Values
(https://docs.google.com/spreadsheets/d/1f988o68HDvk335xXllJD16vxLBuRcmm
3vg6U9lVaYpA/edit#gid=0). Which was posted in the bead color subreddit
beadsprites (https://www.reddit.com/r/beadsprites) under this post Bead
List with RGB Values
(https://www.reddit.com/r/beadsprites/comments/291495/bead_list_with_rgb
_values/).
The generate_instructions.pl script under bin/ has been setup to
optimally be used the 22k bucket of beads from Perler.

USAGE
new
Usage : ->new()
Purpose : Returns FuseBead::From::PNG object
Returns : FuseBead::From::PNG object
Argument :
filename - Optional. The file name of the PNG to process. Optional but if not provided, can't process the png.
e.g. filename => '/location/of/the.png'
unit_size - Optional. The size of pixels squared to determine a single unit of a bead. Defaults to 1.
e.g. unit_size => 2 # pixelated colors are 2x2 in size
whitelist - Optional. Array ref of colors, dimensions or color and dimensions that are allowed in the final plan output.
e.g. whitelist => [ 'BLACK', 'WHITE', '1x1x1', '1x2x1', '1x4x1', 'BLACK_1x6x1' ]
blacklist - Optional. Array ref of colors, dimensions or color and dimensions that are not allowed in the final plan output.
e.g. blacklist => [ 'RED', '1x10x1', '1x12x1', '1x16x1', 'BLUE_1x8x1' ]

process
Usage : ->process()
Purpose : Convert a provided PNG into a list of bead blocks that will allow building of a two dimensional bead replica.

mirror
Usage : ->mirror()
Purpose : Getter / Setter for the mirror option. Set to 1 (true) by default. This option will mirror the image when displaying it as plans. The reason is then the mirror of the image is what is placed on the peg board so that side can be ironed and, when turned over, the image is represented in it's proper orientation.
Returns : Either 1 or 0
Argument : a true or false value that will set whether the plans are mirrored to the image or not
