# Juxtapose Image Thumbnails on a Canvas

Example Usage • Option Summary

Use the `montage` program to create a composite image by combining several separate images. The images are tiled on the composite image optionally adorned with a border, frame, image name, and more. See Command Line Processing for advice on how to structure your `montage` command or see below for example usages of the command.

## Example Usage

We list a few examples of the `montage` command here to illustrate its usefulness and ease of use. To get started, let's montage two images into a single composite:

    magick montage -background '#336699' -geometry +4+4 rose.jpg red-ball.png montage.jpg

Ok, let's add some decorations:

    magick montage -label %f -frame 5 -background '#336699' -geometry +4+4 rose.jpg red-ball.png frame.jpg

You can find additional examples of using `montage` at Examples of ImageMagick Usage and Graphics from the Command Line. Further discussion is available in More Graphics from the Command Line and Examples of ImageMagick Usage.

#### Ashlar Pseudo-image Format

Use the Ashlar pseudo-image format to lay out an image sequence in continuous irregular courses. By default, a reasonable canvas size and border width is determined relative to the image collection you provide. You can explicitedly set the canvas size and border width by appending to the filename, e.g. ashlar:canvas.png[1024x768+4+4]. By default, alignment is along the left edge. Use -define ashlar:best-fit=true to align on both the left and right edges. You can label the image tiles with, for example, -label %f. Here is an example command:

    magick '*.png' -resize 320x320 -label %f ashlar:ashlar.png

This is designed to quickly view a collection of images. To have more control over the layout of your image tiles, use the `montage` command instead.
