This package can create and manipulate bitmaps using binary numbers.

It provides a class that can perform several types of bitmap operations.

Currently, it can:

- Create a bitmap using an array with the bits' numbers set to 1

- Get the intersection of two bitmaps

- Check if two bitmaps are equal

- Add the values of two bitmaps

- Subtract the values of two bitmaps

- Check if a given bit is set

- Convert a bitmap to an array

- Etc...

Usage

Simple usage

use Smoren\BitmapTools\Models\Bitmap;

// Create bitmap by int value:
$bm = Bitmap::create(6); // bitmap: 110

// Create bitmap by true bit positions:
$bm = Bitmap::create([1, 2]); // bitmap: 110

// Basic operations:
$bm = Bitmap::create([0, 2]);
var_dump($bm->getValue()); // 5
var_dump($bm->toArray()); // [0, 2]
var_dump($bm->hasBit(0)); // true
var_dump($bm->hasBit(1)); // false
var_dump($bm->hasBit(2)); // true

$bm = Bitmap::create([0, 1, 2]);
var_dump($bm->getValue()); // 7
var_dump($bm->toArray()); // [0, 1, 2]

$bm = Bitmap::create([]);
var_dump($bm->getValue()); // 0
var_dump($bm->toArray()); // []

// Intersections:
$bm = Bitmap::create(7);
var_dump($bm->intersectsWith(Bitmap::create(1))); // true
var_dump($bm->intersectsWith(Bitmap::create([1, 2]))); // true

$bm = Bitmap::create(6);
var_dump($bm->intersectsWith(Bitmap::create(2))); // true
var_dump($bm->intersectsWith(Bitmap::create(0))); // false

// Inclusions:
$bm = Bitmap::create(6);
var_dump($bm->includes(Bitmap::create(2))); // true (in binary numbers: 110 includes 010)
var_dump($bm->includes(Bitmap::create(1))); // false (in binary numbers: 110 not includes 001)
var_dump($bm->includes(Bitmap::create(3))); // false (in binary numbers: 110 not includes 011)

// Additions:
$bm = Bitmap::create(2); // bitmap: 010
$bm = $bm->add(Bitmap::create(1)); // bitmap: 011
$bm = $bm->add(Bitmap::create(6)); // bitmap: 111

// Subtractions:
$bm = Bitmap::create(15); // bitmap: 1111
$bm = $bm->sub(Bitmap::create(6)); // bitmap: 1001
$bm = $bm->sub(Bitmap::create(3)); // bitmap: 1000
