Create asingle image montagefrom selected images, according to specified layout code: - ’X’ to assembleall
images using an automatically estimated layout. - ’H’ to assemble all images horizontally. - ’V’ to assemble
all images vertically. - ’A’ to assemble all images as an horizontal array. - ’B’ to assemble all images as a
vertical array. - ’Ha:b’ to assemble two blocks ’a’ and ’b’ horizontally. - ’Va:b’ to assemble two blocks ’a’
and ’b’ vertically. - ’Ra’ to rotate a block ’a’ by 90 deg. (’RRa’ for 180 deg. and ’RRRa’ for 270 deg.). -
’Ma’ to mirror a block ’a’ along the X-axis (’MRRa’ for the Y-axis).
Ablock ’a’ can be an image indice (treated periodically) or a nested layout expression ’Hb:c’,’Vb:c’,’Rb’ or
’Mb’ itself.
For example, layout code ’H0:V1:2’ creates an image where image [0] is on the left, and images [1] and [2]
vertically packed on the right.

’boundary’ has different meanings, according to the chosen ’interpolation’ mode : . When ’interpolation=={
-1 | 1 | 2 | 4 }’, ’boundary’ is meaningless. . When ’interpolation==0’, ’boundary’ can be { 0=dirichlet
| 1=neumann | 2=periodic }. . When ’interpolation=={ 3 | 5 | 6 }’, ’boundary’ can be { 0=none
| 1=neumann }.
’ax,ay,az,ac’ set the centering along each axis when ’interpolation=0 or 4’
(set to ’0’ by default, must be defined in range [0,1]).
(no arg) runs interactive mode (uses the instant display window [0] if opened).
