## Description

Returns the shape of a raster band as a list of dimension sizes. The entries
correspond to the dimension names returned by
[RS_DimNames](rs_dimnames.qmd).

For a standard 2D raster this returns `[height, width]`. For an N-dimensional
raster with a time dimension it might return `[12, 256, 256]` meaning 12 time
steps at 256x256 spatial resolution.

When the band index is omitted, all bands must agree on their shape; if
they disagree, an error is returned prompting the user to specify a band
index.

## Examples

```sql
SELECT RS_Shape(RS_Example());
```
