argument when doing color separations. Use <I>ChannelType </I>when
extracting a layer from an image. <I>MatteChannel</I> is useful for
extracting the opacity values from an image. Note that an image may
be represented in RGB, RGBA, CMYK, or CMYKA, pixel formats and a
channel may only be extracted if it is valid for the current pixel

<P>The ColorspaceType enumeration is used to specify the colorspace
that quantization (color reduction and mapping) is done under or to
specify the colorspace when encoding an output image. Colorspaces are
ways of describing colors to fit the requirements of a particular
application (e.g. Television, offset printing, color monitors).
Color reduction, by default, takes place in the <I>RGBColorspace</I>.
Empirical evidence suggests that distances in color spaces such as
<I>YUVColorspace</I> or <I>YIQColorspace</I> correspond to perceptual
color differences more closely han do distances in RGB space. These
color spaces may give better results when color reducing an image.
Refer to <I>quantize</I> for more details.

colorspaces <I>RGBColorspace</I>, <I>CMYKColorspace</I>, and

option is only applicable when writing TIFF, JPEG, and Adobe
Photoshop bitmap (PSD) files.

<P>The image compositor requires a matte, or alpha channel in the

mask which represents a sort of a cookie-cutter for the image.

inside the shape, zero outside, and between zero and 255 on the
boundary. For certain operations, if <I>image</I> does not
have a matte channel, it is initialized with 0 for any pixel
matching in color to pixel location (0,0), otherwise 255 (to work
properly <I>borderWidth</I> must be 0).</P>

<P>Rendering intent is a concept defined by <A HREF="http://www.color.org/">ICC</A>
Spec ICC.1:1998-09, "File Format for Color Profiles".
ImageMagick uses <I>RenderingIntent</I> in order to support ICC
Color Profiles.
</P>
<P STYLE="margin-bottom: 0in">From the specification: "Rendering
intent specifies the style of reproduction to be used during the
evaluation of this profile in a sequence of profiles. It applies
specifically to that profile in the sequence and not to the entire
sequence. Typically, the user or application will set the rendering
intent dynamically at runtime or embedding time."
