[filename pathname]=uigetfile({'*.bmp';'*.jpg'},'File Selector'); image=strcat( pathname, filename) axes(handles.axes1) imshow(image)
This is the code used to load an image.. and the error is in "axes(handles.axes1)" how can i fix this error?

It doesn't know what handles.axes1 is. First use h = findobj('Tag',axes1) and then axes(h). I think it should work.

I searched for it. It won't be possible to do it in the Callback function of your edit text. YOu can do it in another Keypressfcn. But I still am not sure if 'Color' would work with set. Sorry, couldn't be of more help. Post it in another thread. Maybe someone will know the answer.
