composite



SYNOPSIS

       composite [ options ... ] image composite [ mask ] compos­
       ited


DESCRIPTION

       composite composite images to create new images.   compos­
       ite  is  the  base  image  and image contains the changes.
       composited is the result, and normally has the same dimen­
       sions 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  con­
       verted 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
