alindvall 0:b94e330c98ac 28 * An App example. Searches for images on any connected media (USB Mass Storage,
alindvall 0:b94e330c98ac 29 * SD Card or QSPI File System) and presents the images one at a time, scaled to
alindvall 0:b94e330c98ac 30 * fit the display.
alindvall 0:b94e330c98ac 31 *
alindvall 0:b94e330c98ac 32 * The purpose of this example is to show how to recursively search the file
alindvall 0:b94e330c98ac 33 * systems and how to load images. The image scaling could be replaced with
alindvall 0:b94e330c98ac 34 * rotating, cropping or any other image operation. The two second delay between
alindvall 0:b94e330c98ac 35 * images could be replaced with buttons or other touch events.
