| 4 * Above graphic is relationship among major objects of MadButterfly. | |
| 5 * \ref redraw_man_t, redraw manager, is supposed to manage graphic elements, | |
| 6 * shapes, and decide when and who to redraw on the output screen. | |
| 7 * | |
| 8 * \ref shape_t is base-type for all graphic objects. It can be a path, | |
| 9 * a text, a ellipse, ..., or an image. When the states or attributes of | |
| 10 * an graphic | |
| 11 * object changed, managing redraw_man_t, the one that manages the graphic | |
| 12 * object, will be notified. The redraw_man_t will schedule a redrawing | |
| 13 * for every | |
| 14 * dirty objects, changed ones, and relative objects. The relative objects | |
| 15 * are objects effected by changed ones. For example, part of a relative | |
| 16 * object may be hidden before changing, but it is re-explored after chaning. | |
| 17 * The explored part of the object must be redrawed. | |
| 18 * | |
| 19 * The shape of shape objects are variable from type to type. To simplize | |
| 20 * the problem, we use a rectangle to model the area occupied by an object. | |
| 21 * \ref geo_t is the one used to model the rectangle. Shape objects should | |
| 22 * update associated \ref geo_t objects to reflect changing of them-self. | |
| 23 * | |
| 24 * \ref coord_t is used to model transformation in coordinate system. | |
| 25 * A \ref coord_t is actually an transform matrix with additional | |
| 26 * informations. \ref coord_t | |
| 27 * objects are organized as a tree according hierachy of group tags in | |
| 28 * a SVG file. | |
| 29 * | |
| 30 * Colors or patterns used to stroke or fill shapes are described | |
| 31 * by \ref paint_t . Every shape object has a paint, but a paint object | |
| 32 * can be used by multiple shape objects. Once a paint is changed, all | |
| 33 * objects that associate with the paint are dirty. They will be scheduled | |
| 34 * by associated \ref redraw_man_t object to update graphics on | |
| 35 * output screen. | |
