Re: [Libreoffice] Incompatible changes for B-spline smoothing in ODF1.2

In ODF 1.2 the definition of smoothing with B-Splines does it in a way, that you get a real interpolation, that means, the smoothed line goes through all data points. Nicer of course. The current behavior is so inscrutable, that I endorse the definition in ODF1.2. :-) So - lets drop the old version, and upgrade everyone to your nice new code.

But when I have finished it, you can of cause get it for LibreOffice under the MPL/LGPLv3+ dual license. I'll notify you, when I have finished it.

[Libreoffice] Incompatible changes for B-spline smoothing in ODF1.2
Hi all, Currently smoothing with B-Splines uses the inner data points as control points. Therefore the smoothed line does not go through the data points and it is no interpolation. In ODF 1.2 the definition of smoothing with B-Splines does it in a way, that you get a real interpolation, that means, the smoothed line goes through all data points. The current behavior is so inscrutable, that I endorse the definition in ODF1.2. The current way exist at least since StarOffice 5.1. But I do not know, whether anyone really uses it, because it is not suitable for interpolation. On the other hand, there might be users, who know to use control points and have calculated them in a way to get a special, desired line. It is possible to add another method in class SplineCalculater. That it not the problem. But I see no way, to directly store a distinction between the two ways in file format. So a chart in an actual version using the new kind of smoothing looks different in an older version and existing documents will change their appearance when opened in a new version. So, how to handle the change? I like to hear your opinions and ideas. I have put libreoffice@lists.freedesktop.org in CC, because I think it is important for them too and they might not read this mailing list. kind regards Regina ___ LibreOffice mailing list LibreOffice@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/libreoffice
