*
|
|
* This class defines a common interface for @b image objects having
|
|
* an image as their basic graphics. This interface is so that one can
|
|
* tune various properties of the image, like:
|
|
* - smooth scaling,
|
|
* - orientation,
|
|
* - aspect ratio during resizes, etc.
|
|
*
|
|
* Image files may be set via memory buffers, image files, EET files
|
|
* with image data or Edje files. On the last case (which is
|
|
* exceptional), most of the properties cited above will @b not be
|
|
* changeable anymore.
