20 * @brief Demonstrates how to use image scaling modes when loading images.
22 * If an image is going to be drawn on-screen at a lower resolution than it is
23 * stored at on-disk, the scaling feature of the image loader can be used to
24 * reduce the image to save memory, improve performance, and potentially display
25 * a better small version of the image than if the default size were loaded.
27 * The functions CreateImage and CreateImageActor below show how to build an
28 * image using a scaling mode to have %Dali resize it during loading.
30 * This demo defaults to the SCALE_TO_FILL mode of ImageAttributes which makes
31 * sure that every pixel in the loaded image is filled with a source colour
32 * from the image's central region while losing the minimum number of pixels
34 * It is the best option for producing thumbnails of input images that have
35 * diverse aspect ratios.
37 * The other four scaling modes of dali can be cycled-through for the whole
38 * grid using the button in the top-right of the toolbar.
39 * A single image can be cycled by clicking the image directly.
