- A string: an EarthEngine asset id,
- A string and a number: an EarthEngine asset id and version,
- A number or ee.Array: creates a constant image,
- A list: creates an image out of each list element and combines them into a single image,
- An ee.Image: returns the argument,
- Nothing: results in an empty transparent image.
| Usage | Returns |
