NAME

composite - overlaps one image over another.

SYNOPSIS

composite [ options ... ] change-file base-file [ mask-file ] output-image

OVERVIEW

The composite program is a member of the ImageMagick(1) suite of tools. Use it to overlap one image over another.

By default, the image format of `file' is determined by its magic number. To specify a particular image format, precede the filename with an image format name and a colon (i.e. ps:image) or specify the image type as the filename suffix (i.e. image.ps). Specify 'file' as '-' for standard input or output.
