In the following example: http://www.gojs.net/latest/extensions/FloorPlanEditor.html
It shows simple objects being generated from GeoJSON(am I using this term correctly?).
For example, this
F1 M0 0 L50,0 50,90 0,90 0,0 x M0,7 L50,7 x M 0,30 50,30 z
Generates the twin bed image
If I want to have other objects, say a computer monitor, or a CPU casing drawn, how do I get the GeoJSON coordinates?
Is there a program to use that allows me to draw the image I want, or even better, generate the GeoJSON from an existing image?
How do I make the size smaller of all the objects in the palette?
