1925% IsMagickColorSimilar() returns true if the distance between two colors is
1926% less than the specified distance in a linear three dimensional color space.
1927% This method is used by ColorFloodFill() and other algorithms which
1928% compare two colors.
1929%
1930% This implements the equivalent of...
1931% fuzz < sqrt( color_distance^2 * u.a*v.a + alpha_distance^2 )
1932%
1933% Which produces a multi-dimensional cone for that colorspace along the
1934% transparency vector.
1935%
1936% For example for an RGB
1937% color_distance^2 = ( (u.r-v.r)^2 + (u.g-v.g)^2 + (u.b-v.b)^2 ) / 3

3059% QueryMagickColorname() returns a named color for the given color intensity.
3060% If an exact match is not found, a hex value is returned instead. For
3061% example an intensity of rgb:(0,0,0) returns black whereas rgb:(223,223,223)
3062% returns #dfdfdf.

3064% The format of the QueryMagickColorname method is:
3065%
3066% MagickBooleanType QueryMagickColorname(const Image *image,
3067% const PixelPacket *color,const ComplianceType compliance,char *name,

3070% A description of each parameter follows.
3071%
3072% o image: the image.
3073%
3074% o color: the color intensities.
3075%
3076% o Compliance: Adhere to this color standard: SVG, X11, or XPM.
3077%
3078% o name: Return the color name or hex value.
3079%
3080% o exception: return any errors or warnings in this structure.
