# Tools
Some scripts in tools will generate a "map" of your dump, as well as tiles to be rendered in a Leaflet based
visualization thing in your browser.
BE CAREFUL, THESE OPERATIONS TAKE A LOT OF SPACE
ALLOW AROUND 6 TIMES THE SIZE OF YOUR FLASH DUMP
What you are seeing is all the pages stacked together, then the very "high" column is split into 8 smaller colums, that are then stitched together horizontally.
You need to have libvips-tools installed.
Just run the script with a dump file and a page size, and wait for a bit (10ish minutes).
$ bash tools/viz.sh flash_3.bin $((2048+64))
