Computes a tile of pixels by performing an arbitrary computation on image data.
Requests are limited to 32MB in uncompressed data per request, computed as the product of the request dimensions in pixels, the number of image bands requested, and the number of bytes per pixel for each band. Requests are also limited to at most 10000 pixels in either dimension and at most 100 bands. Requests exceeding these limits will result in an error code of 400 (BAD_REQUEST).
If successful, the response body contains the requested pixel data in the encoding specified in the fileFormat
field of the request.
