Detailed Description

read pnm (i.e., portable anymap) files.

Date:

2000/12/10 20:09:13

Revision:

1.11

vtkPNMReader is a source object that reads pnm (portable anymap) files. This includes .pbm (bitmap), .pgm (grayscale), and .ppm (pixmap) files. (Currently this object only reads binary versions of these files.)

PNMReader creates structured point datasets. The dimension of the dataset depends upon the number of files read. Reading a single file results in a 2D image, while reading more than one file results in a 3D volume.

To read a volume, files must be of the form "FileName.<number>" (e.g., foo.ppm.0, foo.ppm.1, ...). You must also specify the DataExtent. The fifth and sixth values of the DataExtent specify the beginning and ending files to read.

Member Function Documentation

vtkPNMReader* vtkPNMReader::New (    )  [static]

Instantiate object with no start, end, or progress methods. Reimplemented from vtkImageReader.

virtual const char* vtkPNMReader::GetClassName (    )  [virtual]

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkImageReader.

int vtkPNMReader::IsTypeOf (  const char *    type )  [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkImageReader.

virtual int vtkPNMReader::IsA (  const char *    type )  [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkImageReader.

vtkPNMReader* vtkPNMReader::SafeDownCast (  vtkObject *    o )  [static]

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkImageReader.

void vtkPNMReader::operator= (  const vtkPNMReader &    )  [inline, protected]

Definition at line 81 of file vtkPNMReader.h.

void vtkPNMReader::ExecuteInformation (    )  [protected, virtual]

Reimplemented from vtkImageReader.
