Hello, everyone!
I am writing my custom reader for my data format.I wrote it and Built it
with some errors!
So I have some questions to ask for help!
Basic information:
My output data type is vtkImageData, so my code was deriven form
vtkImageAlgorithm
1.Should I use *FillInputPortInformation *or *FillOutputPortInformation *like
below
int vtkMyPluginReader::FillOutputPortInformation(int, vtkInformation *info)
{
info->Set(vtkDataObject::DATA_TYPE_NAME(), "vtkImageData");
return 1;
}
*or*
int vtkMyPluginReader::FillInputPortInformation(int, vtkInformation *info)
{
info->Set(vtkAlgorithm::INPUT_REQUIRED_DATA_TYPE(), "vtkImageAlgorithm");
return 1;
}
*Which one is right when I am writing a reader NOT a filter?*
2.My header is like that below. Is that enough for a reader?:
//----------------------------------------------------------------------------
#ifndef __vtkMyPluginReader_h_
#define __vtkMyPluginReader_h_
#include "vtkImageAlgorithm.h"
#include "vtkMyPlugin.h" //Needed for read actual META_DATA
class VTK_EXPORT vtkMyPluginReader : public vtkImageAlgorithm
{
public:
static vtkMyPluginReader *New();
vtkTypeRevisionMacro(vtkMyPluginReader, vtkImageAlgorithm);
void PrintSelf(ostream& os, vtkIndent indent);
vtkSetStringMacro( FileName );
vtkGetStringMacro( FileName );
virtual int ReadMetaData(vtkInformation *outInfo);//Get the actual data
from a data file
protected:
vtkMyPluginReader();
~vtkMyPluginReader();
virtual int RequestData(vtkInformation *, vtkInformationVector **,
vtkInformationVector *);
virtual int RequestInformation(vtkInformation *, vtkInformationVector
**,
vtkInformationVector *);
virtual int FillOutputPortInformation(int, vtkInformation *);
public:
vtkMyplugin pluginfile;
char *FileName;
private:
vtkMyPluginReader(const vtkMyPluginReader&); //Not implemented
void operator=(const vtkMyPluginReader&); //Not implemented
};
#endif
//----------------------------------------------------------------------------
Thank you so much for helping me!
