Member Function Documentation
§ grabFrame()
Captures a single snapshot of the display and writes the data to the given image.
The provided image should have the same dimensions as the configured values (_width and _height)
- Parameters
-
[out] image The snapped screenshot (should be initialized with correct width and height)
- Returns
- Zero on success else negative
