Hi,

I need to add iekELLIPSE objects with various rotation angles (not only 90, 180, 270 degrees).

Is it possible?
If no, can somebody tell me an alternative method?

Thanks in advance,
Giovanni

Hi,

I don't think it's possible with iekELLIPSE (at least in my version of ImageEn).
However, you can construct ellipse using iekPolyline (usually using midpoint algorithm) and then you can rotate polyline.

I have done similar thing with rectangle.

Hi

That is correct. At this time Ellipse objects can only be rotated in 90 deg. increments.

Thanks all. I considered the polyline but wanted to avoid it due to the lot of segments needed to reproduce the curved path of large ellipses. Anyway it seems the only way at the time being.

Nigel, you should consider to add the ellipses rotation to the incoming releases...

Best Regards,
Giovanni
