Resource: Thumbnail
Information about a thumbnail.
| Fields |
name |
string
The resource name representing the thumbnail, of the form "projects/*/thumbnails/**" (e.g. "projects/earthengine-legacy/thumbnails/").
|
expression |
object (Expression)
The expression to compute. Must evaluate to an Image.
|
fileFormat |
enum (ImageFileFormat)
The output encoding in which to generate the resulting image.
|
bandIds[] |
string
If present, specifies a specific set of bands that will be selected from the result of evaluating expression. If not present, all bands resulting from expression will be selected.
|
visualizationOptions |
object (VisualizationOptions)
If present, a set of visualization options to apply to produce an 8-bit RGB visualization of the data.
|
grid |
object (PixelGrid)
An optional pixel grid describing how the image computed by expression is reprojected and clipped.
|
filenamePrefix |
string
Only used when fileFormat is ZIPPED_GEO_TIFF or ZIPPED_GEO_TIFF_PER_BAND.
|
Methods |
|
|
Creates an ID that can be used to render a "thumbnail" image. |
