ImageMagick, version , is a package for display and interactive manipulation montage creates a composite image by combining several separate images. We list a few examples of the montage command here to illustrate its usefulness and ease of use. To get started, let’s . ImageMagick Studio LLC. This operation can be performed using its montage tool. To tile a set of images, allowing ImageMagick to pick the layout for you: To tile a set of.

Back to Contents Description 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 imagemagifk 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 imagmagick 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 kontage per row, the montqge 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. Imzgemagick 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 monatge font, a font is chosen imagemagidk allows the name of the image to fit the maximum width of a tiled area.

The label colors is determined by the -background and -foreground command line argument or X resource. Note, that if the background and foreground colors are the same, labels will not appear. Initially, the composite image title is placed at the top if one is specified refer to -foreground X resource.

Next, each image is set onto the composite image, surrounded by its border color, with its name centered imagemagickk below it. The individual images are left-justified within the width of the tiled image,agick. 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. Note, that if the number of tiles exceeds the default number of imagemxgick 5 per row, 4 per columnmore than one composite image is created.

To ensure a single image is produced, use -tile to increase the imzgemagick of tiles to meet or imagemagjck the number of input images. Finally, to create one or more empty spaces in the sequence of tiles, use the NULL image format. 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: Back to Contents Options -adjoin join images into a single multi-image file.

This option is useful for creating a multi-frame animation sequence within the same file e. The actual number of colors in the image may be less than your request, but never more. Note, this is a color reduction option.

Images with less unique colors than specified with this option will have any duplicate or unused colors removed. Refer to quantize for more details. Note, options -dither-colorspaceand -treedepth affect the color reduction algorithm.

Color reduction, by default, takes place in the RGB color space. These color spaces may give better results when color reducing an image. The Transparent color space behaves uniquely in that it preserves imagemwgick matte channel of the image if it exists.

The -colors or -monochrome option is required for this option to take effect. By default, each image is commented with its file name. Use this option to assign a specific comment to the image.

Optionally you can include the image filename, type, width, height, or scene number by embedding special format characters. If the first character of string isthe image comment is read from a file titled by the remaining characters in the string. By default, each of the composite image pixels are replaced by the corresponding image tile pixel. You can choose an alternate composite operation: None of the image data of image will be in the result.

Note this differs from over because the portion of composite image outside image ‘s shape does not appear in the result. The overlap region will be blank. Output values are cropped to no overflow. This operation is independent of the matte channels. The matte channel is ignored set tofull coverage. The add and subtract operators can be used to perform reversible transformations. This is useful for comparing two very similar images.

Here the matte information is ignored. The image compositor requires an matte, or alpha channel in the image for some operations. This extra channel usually defines a mask which represents a sort of a cookie-cutter for the image. This is the case when matte is full coverage for pixels inside the shape, zero outside, and between zero and on the boundary.


If image does not have an matte channel, it is initialized with 0 for any pixel matching in color to pixel location 0,0otherwise to work properly borderwidth must be 0. This option specifies the type of image compression for the composite image.

See miff 5 for details. The default is the compression type of the specified image file. See X 1 for details about the geometry specification. Use cropping to tile only a particular area of an image. Use -crop 0x0 to remove edges that are the montagge color. The equivalent X resource for this option is cropGeometry class CropGeometry. This option specifies an image density when decoding a Postscript or Portable Document page.

The default is 72 pixels per inch in the horizontal and vertical direction. This option is used in concert with -page. The label font is obtained from the X server. If none is available, the composite image monhage not have labels. Here are the valid methods: The basic strategy of dithering is to trade intensity resolution for spatial imxgemagick by averaging the intensities of several neighboring pixels. Images which suffer from severe contouring when reducing colors can be improved with this option.

Use this option to annotate an image with one or imagenagick graphic primitives. The primitives include rectangle circle polygon color matte text image Rectangletextand image requires an upper left and lower right coordinate. Circle requires the center coordinate and a coordinate on the outer edge. Finally, polygon requires three or more coordinates defining its boundaries. Coordinates are integers separated by an optional comma.

For example, to define a circle centered atthat extends touse: Consider the target pixel as that specified by your imagemwgick.

The point method recolors the target pixel. The replace method recolors any pixel that matches the color of the target pixel. Floodfill recolors any pixel that matches the color of the target pixel and is a neighbor. Finally, reset recolors all pixels.

Use matte to the change the pixel matte value to transparent. Follow the pixel coordinate with a method see the color primitive for a description of methods. The point method changes the matte value of the target pixel. The replace method changes the matte value of any pixel that montagf the color of the target pixel. Floodfill changes the matte value of any pixel that matches the color of the target pixel and is a neighbor. Finally reset changes montafe matte value of all pixels.

Use text to annotate an image with text. Follow the text coordinates with a string. If the string has embedded spaces, enclose it in double quotes.
