示例1: infile
// Make sure that we can forward the LAS_Spec/3 VLR
TEST(LasWriterTest, forward_spec_3)
{
PointTable table;
std::string infile(Support::datapath("las/spec_3.las"));
std::string outfile(Support::temppath("out.las"));
// remove file from earlier run, if needed
FileUtils::deleteFile(outfile);
Options readerOpts;
readerOpts.add("filename", infile);
Options writerOpts;
writerOpts.add("forward", "all,vlr");
writerOpts.add("filename", outfile);
LasReader reader;
reader.setOptions(readerOpts);
LasWriter writer;
writer.setOptions(writerOpts);
writer.setInput(reader);
writer.prepare(table);
writer.execute(table);
PointTable t2;
Options readerOpts2;
readerOpts2.add("filename", outfile);
