Resource Fallback Support
Tizen native applications can run on different types of devices, such as wearable, phone, tablets, and TVs. Tizen also supports various resolutions (WVGA ~ XQXGA) and resources. To take advantage of these features, you can handle resources in the Resource Explorer view in the IDE.
In addition to the possibilities provided by the Resource Explorer 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 based on the container size. The image sets can have the following properties:
-
name: 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. 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.
