#!php

composer require exitus/lib-block-pack

USAGE:

1. Build list of blocks

#!php

$blockList=new Exitus\LibBlockPack\BlockList();
$blockList->add(
        new Exitus\LibBlockPack\Block($id/filename,$width,$height)
    );
$blockList->add(
        new Exitus\LibBlockPack\Block($id/filename,$width,$height)
    );

2. run packer with blockList

#!php

$packer=new Exitus\LibBlockPack\Packer($blockList);
$packer->pack();

3. get X and Y positions for blocks

#!php

foreach ($blockList->getBlocks() as $block) {
	$block->getId();
	$block->getX();
	$block->getY();

	// also methods available if needed
	$block->getWidth();
	$block->getHeight();
