Hi Dao,
Response inline... > interesting, I never think filter oriented... but if I want to highlight a > filled shape, the yellow never appears, isn't it? FWIW, I never saw a way to highlight shapes which works well in all situations. For example, popular ways to highlight objects are: 1. Use a particular stroke/fill color. How will you highlight a shape which by coincidence is in that particular color? 2. Revert colors (a.k.a. XOR mode). How will you highlight a shape which is mid-tone gray? 3. Use the shape's bounding box. If the shape is very large and you are zooming in, for example, you won't have a clue that the shape is selected. Also, this is not quite a "highlight"... I'd advise you to take a look at existing vector graphics editors, such as Inkscape (which seems to use approach 3) and Sketsa (which seems to use approach 1; as a matter of curiosity, it's based in Batik), in order to figure out general approaches to the problem. Also, Batik Squiggle also has a shape highlighting feature (which seems to use approach 2): checkout "Tools"/"DOM Viewer..."/"Click to enable highlight of selected node". Note that the shape highlight doesn't seem to be working well with complex SVG files, but you may use a very simple SVG [1] just to have a feeling: I've just reported bug 48468 to track it down... ;-) Hope this helps, Helder [1] http://heldermagalhaes.com/stuff/svg/demos/SVGObject-HTMLCanvasInteractors/sample.svg [2] https://issues.apache.org/bugzilla/show_bug.cgi?id=48468 --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
