% FloodfillPaintImage() changes the color value of any pixel that matches
% target and is an immediate neighbor. If the method FillToBorderMethod is
% specified, the color value is changed for any neighbor pixel that does not
% match the bordercolor member of image.
%
% By default target must match a particular pixel color exactly.
% However, in many cases two colors may differ by a small amount. The
% fuzz member of image defines how much tolerance is acceptable to
% consider two colors as the same. For example, set fuzz to 10 and the
% color red at intensities of 100 and 102 respectively are now
% interpreted as the same color for the purposes of the floodfill.
%
% The format of the FloodfillPaintImage method is:
%
% MagickBooleanType FloodfillPaintImage(Image *image,
% const ChannelType channel,const DrawInfo *draw_info,
% const MagickPixelPacket target,const ssize_t x_offset,
% const ssize_t y_offset,const MagickBooleanType invert)
%
% A description of each parameter follows:
%
% o image: the image.
%
% o channel: the channel(s).
%
% o draw_info: the draw info.
%
% o target: the RGB value of the target color.
%
% o x_offset,y_offset: the starting location of the operation.
%
% o invert: paint any pixel that does not match the target color.

% FloodfillPaintImage() changes the color value of any pixel that matches
% target and is an immediate neighbor. If the method FillToBorderMethod is

% match the bordercolor member of image.
%
% By default target must match a particular pixel color exactly. However,
% in many cases two colors may differ by a small amount. The fuzz member of
% image defines how much tolerance is acceptable to consider two colors as
% the same. For example, set fuzz to 10 and the color red at intensities of
% 100 and 102 respectively are now interpreted as the same color for the
% purposes of the floodfill.
%

% const ssize_t x_offset,const ssize_t y_offset,
