Transform a 2D polygon ROI with 4 corners into an array of ncols x nrows array of smaller rois
This plugin will take a 2D Polygon ROI (4 corners only) and transform it into an array of smaller polygons, defined by n columns and n rows. The columns can be separated by a space as well as the rows. Each roi will be named by a basename followed by a row and a column index. If the output ROI selected is a line (instead of a box), then vertical lines will be generated only for 1 row.
