# Texture Packer

Pack given bitmaps into a single one.

Note: This library uses a naive rectangle packing algorithm. It's absolutely

not the most efficient one, but implementation complexity is very low.

Example:

```

const Packer = TexturePacker(u8, 20, 50);

var packer = Packer{};

const rect = std.mem.zeroes([10 * 10]u8);

const a = try packer.pushBitmap(10, 10, &rect);

try expectEqual(a.x, 0);

try expectEqual(a.y, 0);

const b = try packer.pushBitmap(10, 10, &rect);

try expectEqual(b.x, 10);

try expectEqual(b.y, 0);

const c = try packer.pushBitmap(10, 10, &rect);

try expectEqual(c.x, 0);

try expectEqual(c.y, 10);

// All packed bitmaps are stored there. 

const result = packer.bitmap;

```
