Leaflet - How to keep original coordinates system effective when using tile layer?

In my Leaflet application I used to display a background layer with an ImageOverlay. But since the image is too big and slow down Leaflet processing, I switch to a tiling approach. I used gdal2tiles-leaflet to generate my tiles. It worked fine. But…

Dividing a rectangle into smaller, equal, integer rectangles/tiles of maximum size

I need to create screenshots with an extremely large resolution. Because the resolution is larger than my renderer supports, they need to be split up into smaller resolutions and stitched together later. I have figured out the stitching/rendering…

Removing or masking the I'th sub-element of a tilted tensor?

I am searching for a way using Tensorflow to extract all of the sub-elements except for the one corresponding to the tensor's index. (eg. if looking at index 1 then only sub-elements 0 and 2 are present) Very similar to this approach using…
