Hi Guy, Can you elaborate a bit more in what cases Opera is slow?
Do you mean when dragging elements on top of other elements? Or do you mean DOM manipulations or the creation of manipulation of elements? If you are talking about DOM manipulations, it really helps if you use the methods .suspendRedraw() and .unsuspendRedraw() Opera renders every once in a while, in contrast to other implementations. Other implementations would render only after a script finished working. As a result Opera is a bit slower, but also more flexible. I you want to improve speed for DOM manipulations you can suppress the update of the screen and call .unsuspendRedraw () after the manipulations are finished. A good example is e.g. http://pilat.free.fr/penrose_loc/penrose.svg. You can really watch opera drawing because unlike other viewers, the redraw is not suspended. If you would use suspendRedraw(), Opera would be much quicker. Andreas PS: but yes, I also saw that the rendering speed is slower when dragging bigger elements on top of other elements. Thats a fact in the current version. It seems like the newest Batik SVN release is best optimised for dragging elements. --- In svg-developers@yahoogroups.com, Guy Morton <[EMAIL PROTECTED]> wrote: > > Has anyone got any feedback or comments regarding the speed of Opera's > engine?
