I need to create a component that will let the user upload an image (non-vector) of their facility's floor plan/s and have the user add where different devices are on the floorplan (so technicians can see where devices are and keep their position).
The options I have looked at usually want a vector or are really meant for maps (i.e. google maps). Our previous version was designed by the last developer and has some ungodly calculations done (the position was handled by percentages value and was calculated by multiplying by 2 and then dividing by 2???).
Any suggestions for a library that can "mapify" or create a grid for images so I can handle setting component positions on them easier?
