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 6 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 (6 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.
