void DGtal::ImageFromSet< Image >::append ( Image &  aImage, const Value &  defaultValue, typename Set::ConstIterator  itBegin, typename Set::ConstIterator  itEnd  )

inlinestatic

Append a Set to an existing image. Only points in the Set between itBegin and itEnd contained in the image domain are considered.

Template Parameters:

Set	model of CDigitalSet

Parameters:

aImage	an image
defaultValue	the default value for points in the set
itBegin	ConstIterator on the set to specify the first point to copy of a Set.
itEnd	ConstIterator on the set to specify the last point to copy of a Set.

static void DGtal::ImageFromSet< TImage >::append ( Image &  aImage, const Set &  aSet, const Value &  defaultValue  )

inlinestatic

Append a Set to an existing image. Only points in the Set contained in the image domain are considered.

Template Parameters:

Set	model of CDigitalSet

Parameters:

aImage	an image
aSet	an instance of Set to convert into an image
defaultValue	the default value for points in the set to copy.

template<typename Set >

Image DGtal::ImageFromSet< Image >::create ( const Set &  aSet, const Value &  defaultValue, const bool  addBorder, typename Set::ConstIterator  itBegin, typename Set::ConstIterator  itEnd  )

inlinestatic

Create an Image from a DigitalSet. The size of the output image is given from the set bounding box.

Template Parameters:

Set	model of CDigitalSet

Parameters:

aSet	an instance of Set to convert into an image
defaultValue	the default value for points in the set
addBorder	if true, we add a border of size 1 of defaultValue around the set.
itBegin	ConstIterator on the set to specify the first point to copy.
itEnd	ConstIterator on the set to specify the last point to copy.

Returns:

an image.
