Transfering image's content to JavaFX

Question

This is my first time ;) so Hello ALL!
1. The project concept - a 2D system representing a buildings top view. An image that represents the building http://img30.imageshack.us/img30/2852/p00.jpg
Rooms, stairs, some other elements are objects - example class
class Room {
string nameOfTeacher;
int nrOfRoom;
WorkingHours theHoursOfTrachersWork;
}So the system lets the user search in which room for example mr Kowalski is. Search -> Kowalski -> the system show a blinking room of mr Kowalski. Then you can click the room and get some more info.
2. General problem - how to transform the room locations and the whole picture to JavaFX. Drawing rectangles by intuition and checking if they fit the screen is stupid - it would take ages.
Another idea that I just developed - loading the image to autocad or gimp and getting all the coordinates of the items + drawing everything in javaFX.
Something simpler maybe? please help, time if of the essence 4 me.
Basically all that matters are the proportions - I could draw with jfx the same building, but probobly they wouldn't match the original picture.

Answer 1

Mmm, no, I mentioned flood fill because the algorithm could be used to detect room borders, not necessarily to change the image...
I see two possible ways of using my idea:
- make a tool (can be done with any language!) to get a floor plan image and spit out a data file with room coordinates;
- just process the image on the fly each time you run your application.
If, as I think, the floor plan image is unlikely to change often, the first solution is probably the best.
Ideally the tool could be totally automated, but detecting rooms complicates the algorithm, it might be simpler to make it interactive: user clicks on a room, tool finds out the bounds, asks for a name, outputs the data.
The said data can even be JavaFX code to integrate to your own code. For example an HashSet of names and Rectangles.
The solution to detect bounds depends on the nature of your plan. I googled a couple of floor plans and they have often "parasital" information in the rooms, like furniture or even name (or doors symbols, etc.). If that info is of distinctive color, it can be ignored.
The idea of the algo is to start from a point: go in four directions (up, down, left, right), continue until we find the color of a wall. Coordinates can be deduced from the coordinates of the found wall pixels.
I might do a proof of concept if I find the time...
