<H1 ALIGN=CENTER>Magick::Color</H1>
<P CLASS="western"><A HREF="#Color">Color</A> is the base color class
in Magick++. It is a simple container class for the pixel red, green,
blue, and alpha values scaled to fit GraphicsMagick's Quantum size.
Normally users will instantiate a class derived from Color which
supports the color model that fits the needs of the application. The
Color class may be constructed directly from an X11-style color
string. As a perhaps odd design decision, <U>the value transparent
black is considered to </U><FONT FACE="Verdana, Arial, Helvetica, sans-serif"><U>represent
</U></FONT><U>an unset value</U> (invalid color) in many cases. This
choice was made since it avoided using more memory. The default Color
constructor constructs an invalid color (i.e. transparent black) and
may be used as a parameter in order to remove a color setting.</P>
<H3><A NAME="Color1"></A>Quantum</H3>
<P CLASS="western">The base type used to represent color samples in
GraphicsMagick is the <I>Quantum</I> type. Pixels are represented by
a structure of <I>Quantum</I> values. For example, an RGB pixel
contains red, green, and blue quantums, while an RGBA pixel contains
red, green, blue, and opacity quantums. The maximum value that a
<I>Quantum</I> can attain is specified by a constant value
represented by the <I>MaxRGB</I> define, which is itself determined
by the number of bits in a <I>Quantum</I>. The <I>QuantumDepth</I>
build option determines the number of bits in a Quantum.</P>
<H3>PixelPacket</H3>
<P CLASS="western" STYLE="margin-bottom: 0in">PixelPacket is the
internal representation of a pixel in GraphicsMagick. GraphicsMagick
may be compiled to support 32, 64, or 128 bit pixels of type
<SPAN LANG="en-US">PixelPacket. </SPAN>This is controlled by the
value of the QuantumDepth define. The default is 32 bit pixels
(QuantumDepth=8), which provides the best performance and the least
resource consumption. If additional color precision or range is
desired, then GraphicsMagick may be compiled with QuantumDepth=16 or
QuantumDepth=32. The following table shows the relationship between
<I>QuantumDepth</I>, the type of <I>Quantum</I>, and the overall
<I>PixelPacket</I> size.

<P CLASS="western">The Color base class is not intended to be used
directly. Normally a user will construct a derived class or inherit
from this class. Color arguments are must be scaled to fit the
Quantum size according to the range of <I>MaxRGB</I>. The Color class
contains a pointer to a <I>PixelPacket</I>, which may be allocated by
the Color class, or may refer to an existing pixel in an image.
</P>
<P CLASS="western">An alternate way to <SPAN LANG="en-US">construct
</SPAN>the class is via an X11-<SPAN LANG="en-US">compatible</SPAN>
color specification string (e.g. Color(“red”) or Color
(“#FF0000”)). Since the class may be constructed from a
string, convenient strings may be passed in place of an explicit
Color object in methods which accept a reference to Color. Color may
also be converted to a std::string for convenience in user
interfaces, and for saving settings to a text file.</P>
