ee.Image.getThumbId
Applies transformations and returns the thumbId.
Returns the thumb ID and optional token, or null if a callback is specified.
| Usage | Returns |
|---|
Image.getThumbId(params, callback) | ThumbnailId |
| Argument | Type | Details |
|---|
this: image | Image | The Image instance. |
params | Object | Parameters identical to ee.data.getMapId, plus, optionally:
dimensions (a number or pair of numbers in format WIDTHxHEIGHT) Maximum dimensions of the thumbnail to render, in pixels. If only one number is passed, it is used as the maximum, and the other dimension is computed by proportional scaling. |
region Geospatial region of the image to render, it may be an ee.Geometry, GeoJSON, or an array of lat/lon points (E,S,W,N). If not set the default is the bounds image. |
|
callback | Function, optional | An optional callback. If not supplied, the call is made synchronously. |

It accepts `params`, an object that defines thumbnail properties like `dimensions` (specifying maximum pixel width and height) and `region` (a geospatial area to render). The function can optionally take a `callback` for asynchronous operation. It returns a `ThumbnailId`, and if a callback is provided, it returns null. If no callback is passed the function executes synchronously. The function operates on an `Image` instance.\n"]]
