magick image or Giotto image object

top_color_range

top possible background colors to return

Value

vector of pixel color frequencies and an associated barplot

Examples

#> 1. read Giotto object
#> 2. read Giotto feature information
#> 3. read Giotto spatial information
#> 3.1 read Giotto spatial shape information
#> 3.2 read Giotto spatial centroid information
#> 3.3 read Giotto spatial overlap information
#> 4. read Giotto image information
