\section{NAME}
composite - composite images together.
\section{Synopsis}
{\bf composite} {\bf [} {\it options\/} {\bf ... ]} {\it image composite\/}
{\bf [} {\it mask\/} {\bf ]} {\it composited\/}
\section{Description}
{\bf composite} composite images to create new images.
The optional {\bf mask} can be used to provide matte information for
{\bf composite}
when it has none or if you want a different mask. A mask image is typically
grayscale and the same size as {\bf composite}. If the image is not grayscale,
it is converted to grayscale and the resulting intensities are used as
matte information.
If {\it composited\/} already exists, you will be prompted as to whether it
should be overwritten.
\section{Examples}
To composite an image of a cockatoo with a perch, use:
\begin{verbatim}
composite cockatoo.miff perch.ras composite.miff
\end{verbatim}
To compute the difference between images in a series, use:
\begin{verbatim}
composite -compose difference series.1 series.2
difference.miff
\end{verbatim}
To composite an image of a cockatoo with a perch starting at location (100,150),
use:
\begin{verbatim}
composite -geometry +100+150 cockatoo.miff
perch.ras composite.miff
\end{verbatim}
To tile a logo across your image of a cockatoo, use
\begin{verbatim}
convert +shade 30x60 cockatoo.miff mask.miff
composite -compose bumpmap -tile logo.png
cockatoo.miff mask.miff composite.miff
\end{verbatim}
To composite a red, green, and blue color plane into a single composite image,
try
\begin{verbatim}
composite -compose CopyGreen red.png green.png
red-green.png
composite -compose CopyBlue red-green.png blue.png
composite.png
\end{verbatim}
\section{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.
