Constructor & Destructor Documentation

◆ PNGImageIO()

itk::PNGImageIO::PNGImageIO ( )
protected

Set the palette of the image.

◆ ~PNGImageIO()

itk::PNGImageIO::~PNGImageIO ( )
overrideprotected

Set the palette of the image.

Member Function Documentation

◆ CanReadFile()

bool itk::PNGImageIO::CanReadFile ( const char *  )
overridevirtual

Determine the file type. Returns true if this ImageIO can read the file specified.

Implements itk::ImageIOBase.

◆ CanWriteFile()

bool itk::PNGImageIO::CanWriteFile ( const char *  )
overridevirtual

Determine the file type. Returns true if this ImageIO can write the file specified.

Implements itk::ImageIOBase.

◆ CreateAnother()

virtual::itk::LightObject::Pointer itk::PNGImageIO::CreateAnother ( ) const
virtual

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::LightProcessObject.

◆ GetColorPalette()

virtual const PaletteType& itk::PNGImageIO::GetColorPalette ( ) const
virtual

Get a const ref to the palette of the image. In the case of non palette image or ExpandRGBPalette set to true, a vector of size 0 is returned

◆ GetNameOfClass()

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

Run-time type information (and related methods).

Reimplemented from itk::ImageIOBase.

◆ New()

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

◆ PrintSelf()

void itk::PNGImageIO::PrintSelf ( std::ostream &  os,
Indent  indent 
) const
overrideprotectedvirtual

Set the palette of the image.

Reimplemented from itk::ImageIOBase.

◆ Read()

void itk::PNGImageIO::Read ( void *  buffer)
overridevirtual

Reads the data from disk into the memory buffer provided.

Implements itk::ImageIOBase.

◆ ReadImageInformation()

void itk::PNGImageIO::ReadImageInformation ( )
overridevirtual

Set the spacing and dimension information for the set filename.

Implements itk::ImageIOBase.

◆ ReadVolume()

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

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

◆ SetColorPalette()

void itk::PNGImageIO::SetColorPalette ( const PaletteType  _arg)
inline

Set the palette of the image.

Definition at line 64 of file itkPNGImageIO.h.

◆ Write()

void itk::PNGImageIO::Write ( const void *  buffer)
overridevirtual

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

Implements itk::ImageIOBase.

◆ WriteImageInformation()

void itk::PNGImageIO::WriteImageInformation ( )
overridevirtual

Writes the spacing and dimensions of the image. Assumes SetFileName has been called with a valid file name.

Implements itk::ImageIOBase.

◆ WriteSlice()

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

Set the palette of the image.

Member Data Documentation

◆ m_ColorPalette

PaletteType itk::PNGImageIO::m_ColorPalette
protected

Set the palette of the image.
