getImageSectionsByBarcode.RdCuts out the area of the image that is covered by each barcode.
getImageSectionsByBarcode(object, barcodes = NULL, expand = 0, verbose = NULL)An object of class SPATA2 or, in case of S4 generics,

Characte vector or NULL. If character, subsets the barcodes
of interest. If NULL, all barcodes are considered.
Specifies image expansion. An image that is cropped based on an image
annotation centers around the image annotation. If expand = 0, the default, the dimensions of the image,
that is width/x-axis and height/y-axis, are set to include only the image annotation area

Logical. If TRUE, informative messages regarding
the computational progress will be printed.
(Warning messages will always be printed.)
A named list. Each slot is named after one barcode. The content is another list that contains the barcode specific image section as well as the x- and y-ranges that were used to crop the section.
