Built-in Patterns
ImageMagick includes a number of built-in (embedded) patterns which may be referenced as if they were an image file. The pattern: format tag may be used via the syntax pattern:name to request an embedded pattern (e.g. pattern:checkerboard). The pattern size is controlled with the -size command line option.
