Your image will be tiles from left bottom corner to top right, without being stretched.
While similar to a Basic Repeat, your image will be repeated with a half step vertically as it moves to the right.
The design now shifts half-step horizontally to the right as you move upwards. This is why it is compared to the pattern of bricks.
Your image will be placed at the very center. If the image does not fill the space, the surrounding space will be blank around it.
Your image will be repeated on a fold from all four corners. This is good for images that have irregular edges that would create an obvious tiled pattern.
