Detailed Description

template<typename TDomain, typename TValue>
class DGtal::ImageContainerByITKImage< TDomain, TValue >

Aim: implements a model of CImageContainer using a ITK Image.

Description of template class 'ImageContainerByITKImage'

Using this container, you can switch from DGtal alogrithms to ITK processing pipeline. The Ownership of the underlying ITK image is shared between the wrapper and the ITK pipeline. If the ITK image region is modified, one should manually update the domain of the wrapper. This is done by calling the updateDomain() method.

Returns the lower and upper bounds as physical points. Note that the location of pixels in ITK are in the center of the square. But in DGtal a lowerBound is in the south-west corner of that square. And an upperBound is the north-east corner of the last pixel.

Returns
physical point of the location of the start index of the region.

◆ getPhysicalPointFromDomainPoint()

Remember that GetOrigin() in ITK is the physical location of the index {0,0...}. Not the location of the start index of the region.

Parameters
domainPointa point holding a point in the DGtal domain. It will be converted to a valid index of the ITK image, taking into account the value of myDomainShift.
Returns
physical point of the index.

◆ myDomainShift

template<typename TDomain , typename TValue >
Point DGtal::ImageContainerByITKImage< TDomain, TValue >::myDomainShift = Point()
private

Apply a shift in the lower and upper bounds. Useful to represent multiple images, or images with physical information, i.e with non-default Origin (see ITK for Origin, Spacing and Direction metadata)

Set it using the function updateDomain(inputDomainShift)

Please note that this is a workaround, DGtal cannot fully work in the Physical Domain. The spacing in DGtal is fixed to 1. This allows to work to represent multiple images with different Origins, but they need to have the same Spacing and Direction for the visualization to be meaningful.

Default to zero.

When is not zero, use getIndexFromDomainPoint and getDomainPointFromIndex to switch between points in the domain and indices in the itk image.
