Member Function Documentation

virtual bool itk::PNGImageIO::CanReadFile (  const char *   )  [virtual]

Determine the file type. Returns true if this ImageIO can read the file specified. Implements itk::ImageIOBase.

virtual bool itk::PNGImageIO::CanWriteFile (  const char *   )  [virtual]

Determine the file type. Returns true if this ImageIO can read the file specified. Implements itk::ImageIOBase.

virtual int itk::PNGImageIO::GetCompressionLevel (   )  [virtual]

Set/Get the level of compression for the output images. 0-9; 0 = none, 9 = maximum.

virtual const char* itk::PNGImageIO::GetNameOfClass (   )  const [virtual]

Run-time type information (and related methods). Reimplemented from itk::ImageIOBase.

Pointer itk::PNGImageIO::New (   )  [static]

Method for creation through the object factory. Reimplemented from itk::LightProcessObject.

void itk::PNGImageIO::PrintSelf (  std::ostream &  os, Indent  indent )  const [protected, virtual]

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from itk::ImageIOBase.

virtual void itk::PNGImageIO::Read (  void *  buffer  )  [virtual]

Reads the data from disk into the memory buffer provided. Implements itk::ImageIOBase.

virtual void itk::PNGImageIO::ReadImageInformation (   )  [virtual]

Set the spacing and diemention information for the set filename. Implements itk::ImageIOBase.

virtual void itk::PNGImageIO::ReadVolume (  void *  buffer  )  [virtual]

Reads 3D data from multiple files assuming one slice per file.

virtual void itk::PNGImageIO::SetCompressionLevel (  int  _arg  )  [virtual]

Set/Get the level of compression for the output images. 0-9; 0 = none, 9 = maximum.

virtual void itk::PNGImageIO::Write (  const void *  buffer  )  [virtual]

Writes the data to disk from the memory buffer provided. Make sure that the IORegion has been set properly. Implements itk::ImageIOBase.

virtual void itk::PNGImageIO::WriteImageInformation (   )  [virtual]

Writes the spacing and dimentions of the image. Assumes SetFileName has been called with a valid file name. Implements itk::ImageIOBase.

void itk::PNGImageIO::WriteSlice (  const std::string &  fileName, const void *  buffer )  [protected]
