Altered a few functions to agree with their versions in AtlasViewer

% removing lines.

%

% Syntax:

%

%   colors = distinguishable_colors(n_colors)

%

% Specify the number of colors you want as a scalar, n_colors. This will

% generate an n_colors-by-3 matrix, each row representing an RGB

% color triple. If you don't precisely know how many you will need in

% slightly more than you think you will need.

%

%   colors = distinguishable_colors(n_colors,bg)

%

% This syntax allows you to specify the background color, to make sure that

% your colors are also distinguishable from the background. Default value

% is white. bg may be specified as an RGB triple or as one of the standard

% "ColorSpec" strings. You can even specify multiple colors:

%

%     bg = {'w','k'}

% or

%     bg = [1 1 1; 0 0 0]

%

% will only produce colors that are distinguishable from both white and

% black.

%

%   colors = distinguishable_colors(n_colors,bg,rgb2labfunc)

%

% By default, distinguishable_colors uses the image processing toolbox's

% color conversion functions makecform and applycform. Alternatively, you

% can supply your own color conversion function.

% Example using the file exchange's 'colorspace':

%   func = @(x) colorspace('RGB->Lab',x);

%   c = distinguishable_colors(25,'w',func);
