(this is when I load an image in axes1)
axes(handles.axes1);
handles.DummyImage = uigetfile({'*.jpg';'*.jpeg';'*.png';'*.bmp'});
guidata(hObject,handles);
I=imread(handles.DummyImage);
imshow(I);
(example of processing method)
axes(handles.axes2);
L=imread(handles.DummyImage);
M=adapthisteq(L);
imshow(M);
(this is what I used to save image)
[FileName, PathName] = uiputfile('*.jpg','*.tif', 'Save As');
Name = fullfile(PathName,FileName);
F=getframe(handles.axes2);
W=frame2im(F);
imwrite(W, Name, 'tif');
*I want to save full size image and not in frame size

Ahmad - since your code is showing the image M in your axes2 as
axes(handles.axes2);
L=imread(handles.DummyImage);
M=adapthisteq(L);
imshow(M);
then why not re-use M to save the image to file as
imwrite(M, Name, 'tif');
Are you grabbing the frame because the "save" code is in a different callback and so you no longer have access to M? If so, you have a couple of options - either save M as a member of the handles structure (use guidata for this), or try to access the image data directly as
[FileName, PathName] = uiputfile('*.jpg','*.tif', 'Save As');
Name = fullfile(PathName,FileName);
% get the handle to the child object axes2
hChildAxes2 = get(handles.axes2,'Children');
% assume one child only and grab the image data
W = get(hChildAxes2(1),'CData');
% write the image to file
imwrite(W, Name, 'tif');
Try the above and see what happens!
