[pdal] crop inside and outside

[Oscar Martinez Rubi]

Thanks for the suggestion!

I looked at the splitter filter and it is not exactly what I want but I think it is easy to tweak it to do what I want to do so I will probably do it that way! I will share the tweak just in case somebody else want that...

As far as I understood from the code the Splitter filter make a grid of the input file so the cells coordinates depend on the extent of the file but in the grid that i want the extent of the cells depend on a global coordinates so I need to somehow pass the grid description to the splitter method. I think is easily doable, right?

Thanks again!

Regards,
O.

The new split command should be exactly what you want.
