For a given input file format and depending on the output file format, some parameters are necessary to build the output.

• Attribute name: specify attribute name to write elevation for PointZ(M) outputs
• Fill Z with: select the attribute (or Z geometry coordinate) to fill Z
• Fill M with: select the attribute (or M value from the geometry) to fill M
• Fill attribute with: ?FIXME

Lines can be resampled by maximum length with a constant value or an attribute (whose value may vary from each line). Each resampled line corresponds to its original points populated with intermediate points to insure that all consecutive points are less distant than the maximum length (maximum length could not be less or equal to zero).
