// .NAME vtkImageMask - Combines a mask and an image.
|
|
// .SECTION Description
|
|
// vtkImageMask combines a mask with an image. Non zero mask
|
|
// implies the output pixel will be the same as the image.
|
|
// If a mask pixel is zero, the the output pixel
|
|
// is set to "MaskedValue". The filter also has the option to pass
|
|
// the mask through a boolean not operation before processing the image.
|
|
// This reverses the passed and replaced pixels.
|
|
// The two inputs should have the same "WholeExtent".
|
|
// The mask input should be unsigned char, and the image scalar type
|
|
// is the same as the output scalar type.
