Hi,

Following code may help you to convert PNG images to eps (COLOUR)

fileName = 'FarmerStats'; % your FILE NAME as string

A = imread(fileName,'png');
set(gcf,'visible','off') %suppress figure
image(A);                
axis image               % resolution based on image
axis off                 % avoid printing axis 
set(gca,'LooseInset',get(gca,'TightInset')); % removing extra white space in figure
saveas(gcf,fileName,'epsc');   % save as COLOR eps file

Make the plot that you want in MATLAB and save the plot as an .eps file

print -depsc figure.eps

or the appropirate -deps option, see the help for print.

imwrite() cannot create eps. Use print(), or use Oliver's File Exchange Contribution "export_fig".

You realize that png is a bitmap image format and eps is traditionally used for vector graphics. While you can embed a bitmap image into it, it is unclear why you would want to convert a bitmap graphic into a vector graphic.
