Thread Subject: get an image array out of a figure

Hi,

I have a fig file which contains mainly the types - 'line' and 'patch'.

I want to get an image of certain size out of this fig.

actually what I need is to load the fig, and get an array which can be saved as an image.

do you have any suggestions?

thanks

If you want to capture a figure or an axes to a matrix, try
to use getframe and frame2im
E.g
    
    im = frame2im(getframe(gcf,rec));

or
    im = frame2im(getframe(gca,rec));

rec is the area to be copied.

thanks a lot - it really helped.

for anybody who might be interested, this is the function:

    open(file);
    h=gca;
    F=getframe(h);
    im=F.cdata;

the input is 'file' - which is a fig file
the output is im - which is rgb image
