Nhiệm vụ chính của module love.graphics là vẽ các đường nét, hình dạng, chữ, các Image (ảnh) cùng những đối tượng Drawable (vẽ được) khác lên mành hình. Nhiệm vụ thứ hai bao gồm việc nạp các file ngoài (các Image và Font) vào bộ nhớ, tạo ra các đối tượng riêng (như ParticleSystem hoặc Canvas) và quản lý những vị trí trên màn hình.

Hệ tọa độ của LÖVE có gốc đặt tại góc bên trái phía trên màn hình, tức là vị trí (0, 0). Trục x nằm ngang, hướng sang phải. Trục y thẳng đứng, hướng xuống dưới.

Trong nhiều trường hợp, bạn vẽ lên các ảnh hoặc hình tính từ vị trí góc trên bên trái (Xem hình trên).

Nhiều hàm được dùng để thao tác trên hệ tọa độ đồ họa, chính là cách mà những tọa độ này tương ứng với màn hình. Bạn có thể thay đổi vị trí, co giãn, và thậm chí xoay hình theo cách này.
