<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.
</p>
<p style="margin-bottom: 0in">When encoding an output image, the
colorspaces <i>RGBColorspace</i>, <i>CMYKColorspace</i>, and
<i>GRAYColorspace</i> may be specified. The <i>CMYKColorspace</i>
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
image for some operations. This extra channel usually defines a
mask which represents a sort of a cookie-cutter for the image.
This is the case when matte is 255 (full coverage) for pixels
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 style="margin-bottom: 0in"><i>FilterTypes</i> is used to adjust
the filter algorithm used when resizing images. Different filters
experience varying degrees of success with various images and can
take sipngicantly different amounts of processing time.
ImageMagick uses the <i>LanczosFilter</i> by default since this
filter has been shown to provide the best results for most images in
a reasonable amount of time. Other filter types (e.g. <i>TriangleFilter</i>)
may execute much faster but may show artifacts when the image is
re-sized or around diagonal lines. The only way to be sure is to test
the filter with sample images.

<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."
