| 16 # Algorithm: | |
| 17 # | |
| 18 # We will parse the first two level of the SVG DOM. collect a table of layer and scene. | |
| 19 # 1. Collect the layer table which will be displayed as the first column of the grid. | |
| 20 # 2. Get the maximum scene number. This will decide the size of the grid. | |
| 21 # 3. When F6 is pressed, we will check if this scene has been defined. This can be done by scan all second level group and check if the current scene number is within the | |
| 22 # range specified by scene field. The function IsSceneDefined(scene) can be used for this purpose. | |
| 23 # 4. If this is a new scene, we will append a new group which duplication the content of the last scene in the same group. The scene field will contain the number from the | |
| 24 # last scene number of the last scene to the current scenen number. For example, if the last scene is from 4-7 and the new scene is 10, we will set the scene field as | |
| 25 # "8-10". | |
| 26 # 5. If this scene are filled screne, we will split the existing scene into two scenes with the same content. | |
