Hi all, attached is a patch that fixes a few problems with r2272 1) When the initial area is created, the area bounds were only updated when a point was added. Lines and shapes were added without updating the area bounds. The patch changes this. 2) The splitMaxSize() method did used the calculated bounds, not the bounds of the elements. Therefore, it did not split the area when the number of elements was small. 3) The LineSizeSplitterFilter did not split a line to parts that are smaller than maxSize, it always added the point that made the bbox of the line too large. If this last point is far away from the others, the bbox is far too large. The patch makes sure that a line is split into parts that are small enough. Regarding the problem described by WanMils picture: This is not yet solved with this patch. I have to create some test cases to analyse this also.
