Antialiasing, both export and enhanced view.

Please, please, please give us back the old method of antialiasing, as in all versions up to CD9. The new method creates havoc with traces and dark simplified objects, leaving ugly white lines around all objects. I'm guessing the old method applied an outer blur, whereas the new method applies an inner, or average blur. The result makes using Tace impractical, and simplifying a number of objects can sometimes be problimatic.

At the very least, can someone tell me why this was changed from the CD9 and earlier versions ?

I've been here a while....I can speak to the "why". In CorelDRAW 9 all outlines are drawn with at least a 1px wide and then anti aliased to the outside....while this doesn't sound like a big deal, it is. When you have a few hundred objects in a graphic and then you try to zoom out, all you could see were the outlines as *every* outline was drawn 1px wide....it also reared it's ugly head when you were exporting to bitmaps with low resolutions as you would come into the same problem. In DRAW 10 the algorithm was changed to "fade" the outlines as one zooms out, which means that as you zoom out to where an outline would need to be drawn with a fractional pixel it now fades to the background color....and if you have no color in the background we assume white. This makes drawings look waaaaaaaaay more balanced when you zoom out or when you export to a bitmap format. One artifact that we picked up from this was when objects butt register it means we have a 1px white line on the screen....this is most noticeable in the PowerTrace window. In CorelDRAW X4 improvements were made to the Tracing algorithm so that it no longer previews with white lines through the trace result. In addition there is now an option in PowerTrace that objects don't have to have all objects butt register, which can help out with the faint white outline assuming you don't need the objects to butt register.

Hi Sark,

Like yourself, those lines drive me crazy, so there is now a solution for you.

In X4 trace results are layered again like old trace versions. I fought hard for this for three reasons;

1. the AA issue on trace result looked bad

2. art for vinyl cutting was not directly usable, since use folk often layer colors entirely over others.Trying try to fill knocked-out spaces pefectly - waste of time.

3. Files sizes for trace results in X3 are much larger, since there are tons of shapes with unwanted subpaths (the knockouts).
