Overview

The EFL UTIL SCREENSHOT API provides functions to capture screenshot. Client can get screenshot image by efl_util_screenshot_take_tbm_surface API with tbm_surface handler.

To take a screenshot, use the following steps:
1. Create the efl_util_screenshot_h handle
2. Initialize the handle information using the efl_util_screenshot_initialize() function
3. Call the efl_util_screenshot_take_tbm_surface() function with the argument efl_util_screenshot_h
Then the captured screen data will be returned to tbm_surface_h handle
4. If no longer needed, call the efl_util_screenshot_deinitialize() function to free the efl_util_screenshot_h
