<H2>DESCRIPTION</H2>
<p>This program is part of <a href="index.html">Netpbm</a>.
<p><b>pnmpaste</b> reads two PNM images as input and inserts the first
image (the "pasted image") into the second (the "base image") at the
specified location, and produces a PNM image the same size and type as
the base image as output. If you don't specify the second file,
<b>pnmpaste</b> reads the base image from Standard Input.
<p><i>x</i> and <i>y</i> specify the location in the base image at
which to put the top left corner of the pasted image, <i>x</i> giving
the horizontal position and <i>x</i> giving the vertical position. A
nonnegative value indicates the number of pixels right of the right
edge or below the top edge of the base image, while a negative value
indicates the number of pixels right of the right edge or below the
bottom edge (so x = -5 means 5 pixels left of the right edge).
<P>If any part of the pasted image does not fit within the base image,
<b>pnmpaste</b> fails.
<p>This tool is most useful in combination with <I>pamcut</I>. For
instance, if you want to edit a small segment of a large image, and
your image editor cannot edit the large image, you can cut out the
segment you are interested in, edit it, and then paste it back in.
<P>Another useful companion tool is <B>pbmmask</B>.
<P><B>pamcomp</B> is a more general tool, except that it lacks the
"or," "and," and "xor" functions.
<B>pamcomp</B> allows you to specify an alpha mask in order to have
only part of the inserted image get inserted. So the inserted pixels
need not be a rectangle. You can also have the inserted image be
translucent, so the resulting image is a mixture of the inserted image
and the base image.
<A NAME="options"> </A>
<H2>OPTIONS</H2>
<P>The option specifies the operation to use when doing the
paste. The default is <B>-replace</B>. The other logical operations
are only allowed if both input images are PBM images. These operations
act as if white is TRUE and black is FALSE.
<P>You can abbreviate all options to their shortest unique prefix.
