For instance, the following example throws a \c CImgInstanceException: -+ \code -+ const CImg<float> img; // Define an empty image. -+ const float value = img.at(0); // Try to read first pixel value (does not exist). -+ \endcode -+ -+ - \b CImgIOException: Thrown when an error occured when trying to load or save image files. -+ This happens when trying to read files that do not exist or with invalid formats. -+ For instance, the following example throws a \c CImgIOException: -+ \code -+ const CImg<float> img("missing_file.jpg"); // Try to load a file that does not exist. -+ \endcode -+ -+ - \b CImgWarningException: Thrown only if configuration macro \c cimg_strict_warnings is set, and -+ when a \CImg function has to display a warning message (see cimg::warn()). -+ -+ It is not recommended to throw CImgException instances by yourself, -+ since they are expected to be thrown only by \CImg. -+ When an error occurs in a library function call, \CImg may display error messages on the screen or on the -+ standard output, depending on the current \CImg exception mode. -+ The \CImg exception mode can be get and set by functions cimg::exception_mode() and -+ cimg::exception_mode(unsigned int). -+ -+ \par Exceptions handling -+ -+ In all cases, when an error occurs in \CImg, an instance of the corresponding exception class is thrown. -+ This may lead the program to break (this is the default behavior), but you can bypass this behavior by -+ handling the exceptions by yourself, -+ using a usual <tt>try { ... } catch () { ... }</tt> bloc, as in the following example: -+ \code -+ #define "CImg.h" -+ using namespace cimg_library; -+ int main() { -+ cimg::exception_mode(0); // Enable quiet exception mode. -+ try { -+ ... // Here, do what you want to stress CImg. -+ } catch (CImgException& e) { // You succeeded: something went wrong! -+ std::fprintf(stderr,"CImg Library Error: %s",e.what()); // Display your custom error message. -+ ... // Do what you want now to save the ship! -+ } -+ } -+ \endcode -+ **/ -+ struct CImgException : public std::exception { -+#define _cimg_exception_err(etype,disp_flag) \ -+ std::va_list ap, ap2; \ -+ va_start(ap,format); va_start(ap2,format); \ -+ int size = cimg_vsnprintf(0,0,format,ap2); \ -+ if (size++>=0) { \ -+ delete[] _message; \ -+ _message = new char[size]; \ -+ cimg_vsnprintf(_message,size,format,ap); \ -+ if (cimg::exception_mode()) { \ -+ std::fprintf(cimg::output(),"\n%s[CImg] *** %s ***%s %s\n",cimg::t_red,etype,cimg::t_normal,_message); \ -+ if (cimg_display && disp_flag && !(cimg::exception_mode()%2)) try { cimg::dialog(etype,_message,"Abort"); } \ -+ catch (CImgException&) {} \ -+ if (cimg::exception_mode()>=3) cimg_library_suffixed::cimg::info(); \ -+ } \ -+ } \ -+ va_end(ap); va_end(ap2); \ -+ -+ char *_message; -+ CImgException() { _message = new char[1]; *_message = 0; } -+ CImgException(const char *const format, ...):_message(0) { _cimg_exception_err("CImgException",true); } -+ CImgException(const CImgException& e):std::exception(e) { -+ const size_t size = std::strlen(e._message); -+ _message = new char[size + 1]; -+ std::strncpy(_message,e._message,size); -+ _message[size] = 0; -+ } -+ ~CImgException() throw() { delete[] _message; } -+ CImgException& operator=(const CImgException& e) { -+ const size_t size = std::strlen(e._message); -+ _message = new char[size + 1]; -+ std::strncpy(_message,e._message,size); -+ _message[size] = 0; -+ return *this; -+ } -+ //!

Class representing an image (up to 4 dimensions wide), each pixel being of type \c 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. -+ -+ \par Image representation -+ -+ A %CImg image is defined as an instance of the container \c CImg<T>, which contains a regular grid of pixels, -+ each pixel value being of type \c 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 <tt>(x,y,z)</tt>, -+ 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 \c CImgList<T> rather than simple images \c CImg<T>. -+ -+ Thus, the \c 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<\c T> are designed to handle this maximum case of (3+1) dimensions. -+ -+ Concerning the pixel value type \c T: -+ fully supported template types are the basic C++ types: <tt>unsigned char, char, short, unsigned int, int, -+ unsigned long, long, float, double, ... </tt>. -+ Typically, fast image display can be done using <tt>CImg<unsigned char></tt> images, -+ while complex image processing algorithms may be rather coded using <tt>CImg<float></tt> or <tt>CImg<double></tt> -+ images that have floating-point pixel values. The default value for the template T is \c 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. -+ -+ \par Image structure -+ -+ The \c CImg<T> structure contains \e six fields: -+ - \c _width defines the number of \a columns of the image (size along the X-axis). -+ - \c _height defines the number of \a rows of the image (size along the Y-axis). -+ - \c _depth defines the number of \a slices of the image (size along the Z-axis). -+ - \c _spectrum defines the number of \a channels of the image (size along the C-axis). -+ - \c _data defines a \a pointer to the \a pixel \a data (of type \c T). -+ - \c _is_shared is a boolean that tells if the memory buffer \c data is shared with -+ another image. -+ -+ You can access these fields publicly although it is recommended to use the dedicated functions -+ width(), height(), depth(), spectrum() 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 \e 1 usually means that the corresponding dimension is \a flat. -+ If one of the dimensions is \e 0, or if the data pointer is null, the image is considered as \e 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 \ref cimg_storage). -+ -+ \par 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: -+ - <tt>CImg<char> img;</tt> declares an empty image. -+ - <tt>CImg<unsigned char> img(128,128);</tt> declares a 128x128 greyscale image with -+ \c unsigned \c char pixel values. -+ - <tt>CImg<double> img(3,3);</tt> declares a 3x3 matrix with \c double coefficients. -+ - <tt>CImg<unsigned char> img(256,256,1,3);</tt> declares a 256x256x1x3 (color) image -+ (colors are stored as an image with three channels). -+ - <tt>CImg<double> img(128,128,128);</tt> declares a 128x128x128 volumetric and greyscale image -+ (with \c double pixel values). -+ - <tt>CImg<> img(128,128,128,3);</tt> declares a 128x128x128 volumetric color image -+ (with \c float pixels, which is the default value of the template parameter \c T). -+ - \b Note: images pixels are <b>not automatically initialized to 0</b>. You may use the function \c fill() to -+ do it, or use the specific constructor taking 5 parameters like this: -+ <tt>CImg<> img(128,128,128,3,0);</tt> declares a 128x128x128 volumetric color image with all pixel values to 0. -+ -+ - Construct images from filenames: -+ - <tt>CImg<unsigned char> img("image.jpg");</tt> reads a JPEG color image from the file "image.jpg". -+ - <tt>CImg<float> img("analyze.hdr");</tt> reads a volumetric image (ANALYZE7.5 format) from the -+ file "analyze.hdr". -+ - \b Note: You need to install <a href="http://www.imagemagick.org">ImageMagick</a> -+ to be able to read common compressed image formats (JPG,PNG, ...) (See \ref cimg_files_io). -+ -+ - Construct images from C-style arrays: -+ - <tt>CImg<int> img(data_buffer,256,256);</tt> constructs a 256x256 greyscale image from a \c int* buffer -+ \c data_buffer (of size 256x256=65536). -+ - <tt>CImg<unsigned char> img(data_buffer,256,256,1,3);</tt> constructs a 256x256 color image -+ from a \c unsigned \c char* buffer \c data_buffer (where R,G,B channels follow each others). -+ -+ The complete list of constructors can be found <a href="#constructors">here</a>. -+ -+ \par Most useful functions -+ -+ The \c CImg<T> class contains a lot of functions that operates on images. -+ Some of the most useful are: -+ -+ - operator()(): Read or write pixel values. -+ - display(): displays the image in a new window. -+ **/ -+ template<typename T> -+ struct CImg { -+ -+ unsigned int _width, _height, _depth, _spectrum; -+ bool _is_shared; -+ T *_data; -+ -+ //!
