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 compos-
ite 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

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.
