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 intensities
       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
