## Detailed Description

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

Represent a list of images CImg<T>.

## Member Typedef Documentation

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');

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.

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 | ( |  | ) |

Destructor.

Destroy current list instance.

Note:
  - Any allocated buffer is deallocated.
  - Destroying an empty list does nothing actually.

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 | ( | 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).

CImgList | ( | const unsigned int | n,
|  | const unsigned int | width,
|  | const unsigned int | height = `1`,
|  | const unsigned int | depth = `1`,

Construct list containing images of specified size.

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.

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

|  | const unsigned int | width,
|  | const unsigned int | height,
