Hi all,
I've a resolution issue while trying to import a TIFF image(size 9932 X 7015) into my GUI. My code is as follows.
handles.f = figure('visible','off',...
'Units','Normalized','Position',[25 25 1300 725],...
'numbertitle','off','Name','Sample_GUI','Menubar','None');
set(handles.f,'toolbar','figure');
handles.TabGroup = uitabgroup('Parent',handles.f, 'Position', [ .01 .01 .98 .975 ]);
handles.Tabs(1) = uitab('Parent',handles.TabGroup, 'Title',' Preprocessing ');
handles.ax2 = axes('Units','Normalized','Position',[0.50,0.40,0.80,0.80],...
'Parent',handles.Tabs(1),'Box','off');
handles.pop1 = uicontrol('style','popupmenu',...
'units','Normalized',...
'position',[.08 .8 .08 .02],...
'string',{'B01','B03'},...
'Parent',handles.Tabs(1),...
'Callback',{@pop1_Callback,handles});
handles.pop1.Visible = 'on';
%call back function for popup menu
function [] = pop1_Callback(varargin)
P = get(handles.pop1,'Value');
disp(P);
if P == 1
matlabImage = imread('B01.tiff');
axis (handles.ax2)
imshow(matlabImage);
elseif P == 2
matlabImage = imread('B03.tif');
axis (handles.ax2)
imshow(matlabImage)
axis off
end
end
I'm able to import the TIFF image into GUI and display, However the resolution so poor that I can barely see the picture.
Can someone help me in fixing this problem.
Thanks in advance.

With an image that large, to see single pixel things on your monitor that is only a fraction as wide as the image, you'll have to zoom in. Otherwise it will subsample to fit onto your display and you'll lose some fine details of the image.
See my attached code on creating a zoom/scroll panel. I got it from the Mathworks and modified it slightly.

What does this say:
>> which -all imscrollpanel
If you do not get this:
C:\Program Files\MATLAB\R2015b\toolbox\images\imuitools\imscrollpanel.p
C:\Program Files\MATLAB\R2015b\toolbox\images\imuitools\imscrollpanel.m % Shadowed
then contact the Mathworks because it's not installed correctly.
There will be no problem using the Image Processing Toolbox in a compiled standalone program. I do it all the time.

why not to use after re sizing with ratio
matlabImage = imread('B03.tif');
[m n x]=size(matlabImage);
ratio=70;
A=imresize(matlabImage,[(m/100)*ratio (n/100)*ratio]);
figure(2)
imshow(A)

Bharath you missed a space in the code. harjeet coded
A=imresize(matlabImage,[(m/100)*ratio (n/100)*ratio]);
but you coded
A = imresize(matlabImage,[(m/100)*ratio(n/100)*ratio]);
missing the space between "ratio" and "(n/100)"
