It will only fill the space row by row, no option is currently provided to do a column-by-column fill of the tile space. Before IM v6. As such a setting such as the first "9x1" image would have been truncated to produce a "7x1" tile image. Because of this, past users of montage often used large numbers such as "x1" to generate a single row of images. Now such a argument will produce a very long image, and could take a long time for IM to complete. As such

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 x 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 Back to Contents Examples To create a montage of a cockatoo, a parrot, and a hummingbird and write it to a file called birds, use: gm montage cockatoo. For example, to make a montage of three images, the first with 32 colors, the second with an unlimited number of colors, and the third with only 16 colors, use: gm montage -colors 32 cockatoo.
