Deal with Arbitrary Field Layout
An arbitrary field layout is a type of plot arrangement that there’s no consistant number of plots exisitng in a row/column. To deal with such scenario, users have to additionally assign centroids for the extra plots. Make sure every plot in the image get assigned a centroid, and it’s ok to have some centroids occupying empty space without plot.
GRID will automatically detect whether the centroid has plot occupied or not, shrinking the space of the empty spots and expanding borders for ones that really cover plots.
