Detailed Description

template<typename T>
struct cimg_library::CImgList< T >

Represent a list of images CImg<T>.

Member Typedef Documentation

iterator

typedef CImg<T>* iterator

Simple iterator type, to loop through each image of a list.

Note

• The CImgList<T>::iterator type is defined as a CImg<T>*.
• You may use it like this:

  CImgList<> list;   // Assuming this image list is not empty
  for (CImgList<>::iterator it = list.begin(); it<list.end(); ++it) (*it).mirror('x');

• Using the loop macro cimglist_for is another (more concise) alternative:

  cimglist_for(list,l) list[l].mirror('x');

const_iterator

typedef const CImg<T>* const_iterator

Simple const iterator type, to loop through each image of a const list instance.

Note

• The CImgList<T>::const_iterator type is defined to be a const CImg<T>*.
• Similar to CImgList<T>::iterator, but for constant list instances.

value_type

typedef T value_type

Pixel value type.

Refer to the pixels value type of the images in the list.

Note

• The CImgList<T>::value_type type of a CImgList<T> is defined to be a T. It is then similar to CImg<T>::value_type.
• CImgList<T>::value_type is actually not used in CImg methods. It has been mainly defined for compatibility with STL naming conventions.

Constructor & Destructor Documentation

~CImgList()

~CImgList

(

)

Destructor.

Destroy current list instance.

Note

• Any allocated buffer is deallocated.
• Destroying an empty list does nothing actually.

CImgList() [1/19]

CImgList

(

)

Default constructor.

Construct a new empty list instance.

Note

• An empty list has no pixel data and its dimension width() is set to 0, as well as its image buffer pointer data().
• An empty list may be reassigned afterwards, with the family of the assign() methods. In all cases, the type of pixels stays T.

CImgList() [2/19]

CImgList ( const unsigned int  n )

explicit

Construct list containing empty images.

Parameters

n	Number of empty images.

Note

Useful when you know by advance the number of images you want to manage, as it will allocate the right amount of memory for the list, without needs for reallocation (that may occur when starting from an empty list and inserting several images in it).

Parameters

n	Number of images.
width	Width of images.
height	Height of images.
depth	Depth of images.
spectrum	Number of channels of images.

Note

Pixel values are not initialized and may probably contain garbage.

Construct list containing images of specified size, and initialize pixel values from a sequence of integers.

Parameters

n	Number of images.
width	Width of images.
height	Height of images.
depth	Depth of images.
spectrum	Number of channels of images.
val0	First value of the initializing integers sequence.

Warning

You must specify at least width*height*depth*spectrum values in your argument list, or you will probably segfault.

CImgList() [6/19]

CImgList	(	const unsigned int	n,
		const unsigned int	width,
		const unsigned int	height,
		const unsigned int	depth,
		const unsigned int	spectrum,

	)

Construct list containing images of specified size, and initialize pixel values from a sequence of doubles.

Parameters

n	Number of images.
width	Width of images.
height	Height of images.
depth	Depth of images.
spectrum	Number of channels of images.
val0	First value of the initializing doubles sequence.
