For an specific example to split a product into several tiles, please have a look here:

Split product into tiles by pixel region

The attached graph shall show how to create equally sized tiles out of one product. It assumes that the product has a known size and if applied to multiple products that all have the same size. if this does not applies the products need to be made equal. For this purpose the Resampling can be used. How to do this is not part of this graph description. Obviously it can happen that at the border the size can not be equal anymore. In this case you need to adapt the pixel region accordingly. This …
