NAME
       composite - composite images together.

SYNOPSIS
       composite [ options ... ] image composite [ mask ] composited

DESCRIPTION
       composite  composite  images  to create new images.  composite is the base image and image
       contains the changes.  composited is the result, and normally has the same  dimensions  as
       composite.

       The  optional mask can be used to provide matte information for composite when it has none
       or if you want a different mask. A mask image is typically grayscale and the same size  as
       composite. If mask is not grayscale, it is converted to grayscale and the resulting inten-
       sities are used as matte information.

EXAMPLES
       To composite an image of a cockatoo with a perch, use:

	   composite cockatoo.miff perch.ras composite.miff

       To compute the difference between images in a series, use:

	   composite -compose difference series.2 series.1
		     difference.miff

       To composite an image of a cockatoo with a perch starting at location (100,150), use:

	   composite -geometry +100+150 cockatoo.miff
		     perch.ras composite.miff

       To tile a logo across your image of a cockatoo, use

	   convert +shade 30x60 cockatoo.miff mask.miff
	   composite -compose bumpmap -tile logo.png
		     cockatoo.miff mask.miff composite.miff

       To composite a red, green, and blue color plane into a single composite image, try

	   composite -compose CopyGreen green.png red.png
		     red-green.png
	   composite -compose CopyBlue blue.png red-green.png
		     composite.png

OPTIONS
       Options are processed in command line order. Any option you specify on  the  command  line
       remains in effect only for the image that follows.  All options are reset to their default
       values after each image is read.
