123
Abstract base class defining the interface for an image. This is the top-level interface to the <a class="el" href="namespaceExiv2.html">Exiv2</a> library.
124
125
Most client apps will obtain an <a class="el" href="classExiv2_1_1Image.html">Image</a> instance by calling a static <a class="el" href="classExiv2_1_1ImageFactory.html">ImageFactory</a> method. The <a class="el" href="classExiv2_1_1Image.html">Image</a> class can then be used to to read, write, and save metadata.
