%APPLYHATCH_PLUSCOLOR Apply hatched patterns to a figure in BW or Color
%  APPLYHATCH_PLUSCOLOR(H,PATTERNS) creates a new figure from the figure H by
%  replacing distinct colors in H with the black and white
%  patterns in PATTERNS. The format for PATTERNS can be
%    a string of the characters:
%    '/', '\', '|', '-', '+', 'x', '.', 'c', 'w', 'k'
%    (see makehatch_plus.m for more details) or
%    a cell array of matrices of zeros (white) and ones (black)
%
%  In addition, H can alternatively be a uint8 NxMx3 matrix of the type
%  produced by imread.  In this case, colors in this image will be
%  replaced with patterns as if it was a figure.  A final figure window
%  will be generated that displays the result.  The DPI argument
%  discussed below will be ignored if H is an image matrix.
%
%  APPLYHATCH_PLUSCOLOR(H,PATTERNS,CVBW) binary value for choice of Color or Black
%  and White plots. If color is chosen the color will match that of the 
%  current fill. 1 -> Color, anything else -> BW
%
%  APPLYHATCH_PLUSCOLOR(H,PATTERNS,CVBW,HINVERT) binary value to invert the hatch.
%  i.e., if it is black lines with a white background, that becomes white
%  lines with a black background. This can either be a scalar value or a 
%  1xN array equal to the length of PATTERNS. When used as an array each
%  PATTERNS(i) will be inverted according to Hinvert(i). 1 -> Invert,
%  anything else -> Non Inverted
%
%  APPLYHATCH_PLUSCOLOR(H,PATTERNS,CVBW,HINVERT,COLORS) maps the colors in the n by 3
%  matrix COLORS to PATTERNS. Each row of COLORS specifies an RGB
%  color value.
%
%  Note this function makes a bitmap image of H and so is limited
%  to bitmap output.
%
%  Additional arguments:
%
%  [im_hatch,colorlist] = applyhatch_plus(h,patterns,CvBW,Hinvert,colorlist,dpi,hatchsc,linewidth)
%
%   input   DPI         allows specification of bitmap resolution, making plot resolution
%                       better for printing.  Ignored if H is an image matrix.
%           HATCHSC     multiplier for hatch scale to increase size of pattern for better operation
%                       at higher resolutions
%                       default [] uses screen resolution as in
%                       APPLYHATCH
%           LINEWIDTH   A scaling factor to apply to line and dot sizes
%                       in hatching.  Defaults to 1.
%   output  IM_HATCH    RGB bitmap matrix of new figure
%                       use IMWRITE to output in desired format
%           COLORLIST   List of colors actually replaced.  Useful info if
%                       no colorlist initially given to function.
%                       Colorlist will be uint8, not 0-1 scale as
%                       originally specified.

%  Example 1:
%    bar(rand(3,4));

%    imwrite(im_hatch,'im_hatch.png','png')
