The ImageEditor application

In this chapter, we will build an application that can be used to edit images, so we will name it ImageEditor. To edit an image with a GUI application, the first step is opening and viewing the image with that application, which is what we did in the previous chapter. Therefore, I decided to make a copy of the ImageViewer application and rename it ImageEditor, before adding the image editing features to it.

Let's start by copying the sources:

    $ mkdir Chapter-02
    $ cp -r Chapter-01/ImageViewer/ Chapter-02/ImageEditor
    $ ls Chapter-02
    ImageEditor
    $ cd Chapter-02/ImageEditor
    $ make clean
    $ rm -f ImageViewer

With these commands, we copy the ImageViewer directory under the Chapter-01 directory to Chapter-02/ImageEditor. Then, we can enter that directory, run make clean to clean all intermediate files that were generated in the compiling...
