montage creates a composite image by combining several separate
images. The images are tiled on the composite image with the name of the
image optionally appearing just below the individual tile.
The composite image is constructed in the following manner. First, each
image specified on the command line, except for the last, is scaled to
fit the maximum tile size. The maximum tile size by default is 120x120.
It can be modified with the -geometry command line argument or X
resource. See
Options
for more information on command line arguments. See
X(1) for more information on X resources.
Note that the maximum tile size need not be a square.
Next the composite image is initialized with the color specified by the
-background
command line argument or X resource. The width and height of the composite
image is determined by the title specified, the maximum tile size, the
number of tiles per row, the tile border width and height, the image border
width, and the label height. The number of tiles per row specifies how
many images are to appear in each row of the composite image. The default
is to have 5 tiles in each row and 4 tiles in each column of the composite.
A specific value is specified with -tile. The tile border width
and height, and the image border width defaults to the value of the X resource
-borderwidth. It can be changed with the -borderwidth or
-geometry command line argument or X resource. The label height
is determined by the font you specify with the -font command line
argument or X resource. If you do not specify a font, a font is chosen
that allows the name of the image to fit the maximum width of a tiled area.
The label colors is determined by the -background and -fill
command line argument or X resource. Note, that if the background and pen
colors are the same, labels will not appear.
Initially, the composite image title is placed at the top if one is specified
(refer to -fill). Next, each image is set onto the composite image,
surrounded by its border color, with its name centered just below it. The
individual images are left-justified within the width of the tiled area.
The order of the images is the same as they appear on the command line
unless the images have a scene keyword. If a scene number is specified
in each image, then the images are tiled onto the composite in the order
of their scene number. Finally, the last argument on the command line is
the name assigned to the composite image. By default, the image is written
in the MIFF format and can be viewed or printed with
display(1).
Note, that if the number of tiles exceeds the default number of 20 (5 per
row, 4 per column), more than one composite image is created. To ensure
a single image is produced, use -tile to increase the number of
tiles to meet or exceed the number of input images.
Finally, to create one or more empty spaces in the sequence of tiles, use
the "NULL:" image format.
Note, a composite MIFF image displayed to an X server with
display
behaves differently than other images. You can think of the composite as
a visual image directory. Choose a particular tile of the composite and
press a button to display it. See display(1) and miff(5)
