# We could check the first file's dimensions to determine behaviour (horizontal or vertical tiling)
# However, the following would only work if we didn't recursively call tile with ever growing chunks 
# where the aspect ratio does not indicate intent...
#tileparam=$(identify $1 | awk '{ print $3 }' | awk -Fx '{ if ( $1 < $2 ) print "x1"; else print "1x" }')

# ...so check for an explicit parameter instead.
# Assumes vertical strips (horizontal tiling)
# this is a bit backwards, the parameter refers to the strip type, opposite to the tiling direction 
tileparam=x1
