Below is the header files for the ImageLib.h
The test image file can be anything. the .lib and .pdb files has things in it that I don't understand at all. I will post a screenshot about it below.
If you don't need to use the pre-defined files to build the class, that's fine as well. I can change the code that uses the pre-defined files later. But please comment on code that will be similar to the heading files that I gave. For example, there is a constructor that ask us to use a filename. if the class is ImageLib, the constructor would be something like ImageLib(ReadGIF(string filename)).
C++ Language. If possible, explain why you did what you did.
Thanks!
You are to create a new class representing images. Remember that your project should be created as an "Empty project," so that you don't get precompiled header code among other things. In order to create this class you should continue to use the files for working with images from the previous programming assignment: ImageLib.h , ImageLib.lib, ImageLib.pdb. Here is a new test image: test2.gif The assignment has two parts. First, you will play the role of class designer and create a new class for images. Second, you will play the role of developer using the class you wrote. For the second part, you should use your class, but not make any assumptions about the implementation of the class (and don't write new member operations to solve that part). Your image class should include (at least) the following capabilities. Use my image library as much as possible to make these simple. For example, store an image variable in your private data. Use Read GIF to implement the first constructor, etc. Constructor using a filename (read from a file) Constructor using just the number of rows and columns (create a blank, black image) Copy constructor, destructor, operator= (these are important, since ImageLib uses dynamic memory!) Accessors for the number of rows and columns in the image Accessor and mutator functions for individual image pixels Output to a file Overload the == and != operator for comparison of images (every pixel must be the same) Overload the > and using namespace std; /* * Type definitions typedef unsigned char byte; // A single byte of data typedef struct { byte red; byte green; byte blue; } pixel; I/ A pixel stores 3 bytes of data: // intensity of the red component // intensity of the green component // intensity of the blue component // // A simple image data structure: // rows is the height of the image (the number of rows of pixels) // cols is the width of the image (the number of columns of pixels) // pixels is a 2D array of the image pixels The first dimension of pixels varies from oto rows-1 The second dimension of pixels varies from o to cols-1 The pixel at row i and column j is accessed by pixels[i][j] With the following definition: // image myimage; // We could access the red component of the pixel at row 10, column 20 by: // myimage.pixels[10] [20].red typedef struct { int rows, cols; /* pic size */ pixel **pixels; /* image data */ } image; * Function prototypes */ * ReadGIF: Preconditions: filename refers to a file that stores a GIF image.

Each pixel has red = @, green -e, blue = e.
