Here's a working template of a GeoReader plugin:
#include <DDImage/GeoReader.h>
using namespace DD::Image;
class templateReader: public GeoReader {
protected:
void geometry_engine(Scene& scene, GeometryList& out) {
printf("templateReader::geometry_engine(), do something clever here.\n");
}
public:
static const Description description;
templateReader(ReadGeo* geo, int fd) : GeoReader(geo) {
printf("templateReader::ctor()\n");
}
};
static bool test(int fd, const unsigned char* block, int length) {
printf("templateReader::test() return true if file is correct type\n");
return true;
}
static GeoReader* build(ReadGeo* op, int fd, const unsigned char* b, int n) {
printf("templateReader::build()\n");
return new templateReader(op, fd);
}
const GeoReader::Description templateReader::description("template\0", build,
test);
