# filters.separatescanline

The Separate scan line Filter takes a single `PointView` as its input and creates a `PointView` for each scan line as its output. `PointView` must contain the `EdgeOfFlightLine` dimension.

Default Embedded Stage

This stage is enabled by default

## Example

The following pipeline will create a set of text files, where each file contains only 10 scan lines.

    [
        "input.text",
        {
            "type":"filters.separatescanline",
            "groupby":10
        },
        "output_#.text"
    ]

## Options

groupby

  The number of lines to be grouped by. [Default : 1]

where

  An expression that limits points passed to a filter. Points that don’t pass the expression skip the stage but are available to subsequent stages in a pipeline. [Default: no filtering]

where_merge

  A strategy for merging points skipped by a ‘where’ option when running in standard mode. If `true`, the skipped points are added to the first point view returned by the skipped filter. If `false`, skipped points are placed in their own point view. If `auto`, skipped points are merged into the returned point view provided that only one point view is returned and it has the same point count as it did when the filter was run. [Default: `auto`]
