[pdal] Using PDAL for the first time

[José Antonio Carmena]

Using no pipeline return no PointView at all in views:
            pdal::Options opts;            opts.add("filename", src);
            pdal::StageFactory pdalFactory;            pdal::Stage *reader = pdalFactory.createStage(driver);            reader->setOptions(opts);
            pdal::PointTable table;            reader->prepare(table);            reader->execute(table);
            // partirlo en trozos            pdal::ChipperFilter chipper; // default: 5000 puntos            chipper.prepare(table);            pdal::PointViewSet views = chipper.execute(table);

 Hello.
I don't know if this is the right place to ask this query. The thing is that I am using PDAL for the first time in the context of an application written in C++. I am trying to create a pipeline with two stages: a reader that reads a LAS and a Chipper filter that splits it into chunks. The code (summarized) is as follows:
        pdal::PipelineManager pipeline.
        pipeline.makeReader(
            src, // const std::string& inputFile,            std::string());
        pipeline->makeFilter("filters.chipper");
        pipeline->execute();

As I understand it, after execute() pipeline-views() should return a set of PointViews, each of which should have about 5000 points. Unfortunately, pipeline-views().size() returns one, a single PointView with about 400,000 points. What am I doing wrong?

Thanks in advance!
