# video.binarytexturepacker

Binary tree based texture packer.

struct BinaryTexturePacker;

  Binary tree based texture packer. Handles allocation of texture page space.

  To fit a texture, space is subdivided vertically/horizontally to create an area fitting texture width/height, try to fit the texture to that area, if it doesn't fit, subdivide again, repeat.

  this(const(Vector2!(uint)) size);

    Construct BinaryTexturePacker.

    Parameters:

    const(Vector2!(uint)) size | Size of texture area for the packer to manage.

  bool allocateSpace(const Vector2u size, out Rectu texArea);

    Try to allocate space for a texture with given size.

    Parameters:

    Vector2u size | Size of texture space to allocate.
    Rectu texArea | Area taken by the texture will be returned here.

    Returns:
    True if successful, false otherwise.
  void freeSpace(ref const Rectu area);

    Free space taken by a texture.

    Parameters:

    Rectu area | Area of the texture to free.

  const pure @property bool empty();

    Determine if this BinaryTexturePacker is empty.

  const @property string info();

    Return a string containing information about the packer.
