Resource Fallback Support

Tizen native applications can run on different types of devices, such as wearable, phone, tablet, and TV. Tizen also supports various resolutions (WVGA ~ XQXGA) and resources. To take advantage of these features, you can handle resources in the Resource Manager view in Tizen Studio.

In addition to the possibilities provided by the Resource Manager view, you can use Edje to provide sets of alternative images in your application.

The image set elements are used to display a specific image on the screen depending on the container size. The image set is used to control the resource quality when the image part is scaled to multiple devices. According to the size of the part’s container, an appropriate image is loaded.

The image sets can have the following properties:

  • image: image-name

    Specifies the name of the image file.

  • size: minw minh maxw maxh

    Specifies the minimum and maximum size that causes a specified image to be selected and shown.

Example: Image set implementation

Image set

   group {
      name: "property_test";

      images {
         set {
            name: "alternative_animal";
            image {
               image: "pig.png" COMP;
               size: 640 800 1200 1500;
            }
            image {
