Detailed Description

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

Class representing an image (up to 4 dimensions wide), each pixel being of type T.

This is the main class of the CImg Library. It declares and constructs an image, allows access to its pixel values, and is able to perform various image operations.

Image representation
A CImg image is defined as an instance of the container CImg<T>, which contains a regular grid of pixels, each pixel value being of type T. The image grid can have up to 4 dimensions : width, height, depth and number of channels. Usually, the three first dimensions are used to describe spatial coordinates (x,y,z), while the number of channels is rather used as a vector-valued dimension (it may describe the R,G,B color channels for instance). If you need a fifth dimension, you can use image lists CImgList<T> rather than simple images CImg<T>.

Thus, the CImg<T> class is able to represent volumetric images of vector-valued pixels, as well as images with less dimensions (1D scalar signal, 2D color images, ...). Most member functions of the class CImg<T> are designed to handle this maximum case of (3+1) dimensions.

Concerning the pixel value type T : fully supported template types are the basic C++ types : unsigned char, char, short, unsigned int, int, unsigned long, long, float, double, ... . Typically, fast image display can be done using CImg<unsigned char> images, while complex image processing algorithms may be rather coded using CImg<float> or CImg<double> images that have floating-point pixel values. The default value for the template T is float. Using your own template types may be possible. However, you will certainly have to define the complete set of arithmetic and logical operators for your class.

Image structure
The CImg<T> structure contains six fields :
  • width defines the number of columns of the image (size along the X-axis).
  • height defines the number of rows of the image (size along the Y-axis).
  • depth defines the number of slices of the image (size along the Z-axis).
  • dim defines the number of channels of the image (size along the V-axis).
  • data defines a pointer to the pixel data (of type T).
  • is_shared is a boolean that tells if the memory buffer data is shared with another image.

You can access these fields publicly although it is recommended to use the dedicated functions dimx(), dimy(), dimz(), dimv() and ptr() to do so. Image dimensions are not limited to a specific range (as long as you got enough available memory). A value of 1 usually means that the corresponding dimension is flat. If one of the dimensions is 0, or if the data pointer is null, the image is considered as empty. Empty images should not contain any pixel data and thus, will not be processed by CImg member functions (a CImgInstanceException will be thrown instead). Pixel data are stored in memory, in a non interlaced mode (See cimg_storage).

Image declaration and construction
Declaring an image can be done by using one of the several available constructors. Here is a list of the most used :

  • Construct images from arbitrary dimensions :
    • CImg<char> img; declares an empty image.
    • CImg<unsigned char> img(128,128); declares a 128x128 greyscale image with unsigned char pixel values.
    • CImg<double> img(3,3); declares a 3x3 matrix with double coefficients.
    • CImg<unsigned char> img(256,256,1,3); declares a 256x256x1x3 (color) image (colors are stored as an image with three channels).
    • CImg<double> img(128,128,128); declares a 128x128x128 volumetric and greyscale image (with double pixel values).
    • CImg<> img(128,128,128,3); declares a 128x128x128 volumetric color image (with float pixels, which is the default value of the template parameter T).
    • Note : images pixels are not automatically initialized to 0. You may use the function fill() to do it, or use the specific constructor taking 5 parameters like this : CImg<> img(128,128,128,3,0); declares a 128x128x128 volumetric color image with all pixel values to 0.

  • Construct images from filenames :
    • CImg<unsigned char> img("image.jpg"); reads a JPEG color image from the file "image.jpg".
    • CImg<float> img("analyze.hdr"); reads a volumetric image (ANALYZE7.5 format) from the file "analyze.hdr".
    • Note : You need to install ImageMagick to be able to read common compressed image formats (JPG,PNG, ...) (See cimg_files_io).

  • Construct images from C-style arrays :
    • CImg<int> img(data_buffer,256,256); constructs a 256x256 greyscale image from a int* buffer data_buffer (of size 256x256=65536).
    • CImg<unsigned char> img(data_buffer,256,256,1,3,false); constructs a 256x256 color image from a unsigned char* buffer data_buffer (where R,G,B channels follow each others).
    • CImg<unsigned char> img(data_buffer,256,256,1,3,true); constructs a 256x256 color image from a unsigned char* buffer data_buffer (where R,G,B channels are multiplexed).

The complete list of constructors can be found here.

Most useful functions
The CImg<T> class contains a lot of functions that operates on images. Some of the most useful are :

  • operator()(), operator[]() : allows to access or write pixel values.
  • display() : displays the image in a new window.
