I've exported a tile layer from qGis using QMetaTiles plugin.
It outputs a folder that contains a lot of images (the tiles). But most of those images are blank (full transparency, no visual data); and there is no option in the plugin for not rendering those.
So i'm looking for a tool that would be able to detect (and delete) images if they are empty; so I don't have to upload them.
Does anyone knows a good (simple) tool ?
