function applyhatch(h,patterns,colorlist) %APPLYHATCH Apply hatched patterns to a figure % APPLYHATCH(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', '.' % a cell array of matrices of zeros (white) and ones (black) % % APPLYHATCH(H,PATTERNS,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 low-resolution, bitmap output. % % Example 1: % bar(rand(3,4)); % applyhatch(gcf,'\-x.'); % % Example 2: % colormap(cool(6)); % pie(rand(6,1)); % legend('Jan','Feb','Mar','Apr','May','Jun'); % applyhatch(gcf,'|-+.\/',cool(6)); % % See also: MAKEHATCH % By Ben Hinkle, % This code is in the public domain. oldppmode = get(h,'paperpositionmode'); oldunits = get(h,'units'); set(h,'paperpositionmode','auto'); set(h,'units','pixels'); figsize = get(h,'position'); if nargin == 2 colorlist = []; end bits = hardcopy(h,'-dzbuffer','-r0'); set(h,'paperpositionmode',oldppmode); bwidth = size(bits,2); bheight = size(bits,1); bsize = bwidth * bheight; if ~isempty(colorlist) colorlist = uint8(255*colorlist); [colors,colori] = nextnonbw(0,colorlist,bits); else colors = (bits(:,:,1) ~= bits(:,:,2)) | ...
