function save_as_png(filename)
% Save current figure as a png file named filename.png
% This routine works around MATLAB problems with filled areas
% by saving to a bmp file first, and then converting to a png
% usage: save_as_png('myfile')

%create the new file name with .png appended
newfilename = [filename '.png']; 

% disable the conversion of the background

% save it to a temporary bmp file
% bmps use Ghostscript which works better for filled objects

% read the temporary bmp file in
img = imread('tmp.bmp'); 

% delete the temporary file

% save the image with the specified filename
imwrite(img,newfilename); figure

end % end of save_as_png
