Value counts of a raster's picture bands over a fixed value range, so the histograms of tiles taken with the same range and bin count can be added with mergeRasterHistograms.
range
The value range the bins cover: bin 0 is min, the last bin is max.
min
max
Counts per picture band (1 or 3), each with the same number of bins.
Pixels counted (transparent and no-data pixels are not).
