% VL_DEMO_PRINT
% VL_DEMO_PRINT(NAME) prints the current figure to the documentation
% directory with the specified filename, assuming that the global
% variable VL_DEMO_PRINT is defined and non-empty when MATLAB is
% started (our using SETENV() from MATLAB). Otherwise the function
% flushes the displays and returns.
%
% VL_DEMO_PRINT(NAME, R) specifies a magnification factor R, setting
% the figure width relatively to the page width. If not specified, R
% is assumed to be 1/2.
%
% Remarks:: The figure paper type is set to letter, that has size 8.5 x
% 11 inches. When converted for web viewing, images are rasterized
% at either 75 or 95 DPI, The documentation system converts images
% to bitmap with a resolution of 75 DPI, which makes a letter size
% page 637 or 808 pixels large, repsectively.
%
% In MATLAB font sizes are usually expressed in points, where a
% point is a 1/72 inch. Thus a 12pt font sampled at 75 DPI is
% about 12.5 pixels high.
