Can I use a uicontrol with imshow?

Hello fellows. I have a code which dicom slice images are shown through imagesc and uicontrol. It works fine. However, I would like to use imshow instead of imagesc, but keeping the slider on the windows.

I figured that imshow with uicontrol does not work... So, is there anything in that sense I could do?

Thanks in advance

figure(10), imagesc(I10(:,:,1)); title('ROI');

hf9 = uicontrol('Style', 'Slider', 'SliderStep', [1/24 1], 'Value', 1, 'Min', 1, 'Max', 25, 'Callback', 'callbackslider_tocrop10');

hpop = uicontrol('Style', 'popup', 'String', 'hsv|hot|cool|gray|jet', 'Position', [300 0 50 25], 'Callback', 'setmap');

Did you try imshow():

imshow(I10(:,:,1));

I would imagine so, so what went wrong?

Hi Image Analyst. Yes, I did try it. I did the changes in the function callbackslider_tocrop10 as well, which the slider is applied on I10. But it did not work. I am using R2010a by the way.

%CallBack to run over the slices in the transverse axis

figure(1),imshow(I10(:,:,get(hf,'Value')));

title(num2str(get(hf,'Value')));

Bellow there is the error. It appears when I try to slide in the window.

??? Error using ==> get Invalid handle object.

Error in ==> callbackslider01 at 3 title(num2str(get(hf,'Value')));

??? Error while evaluating uicontrol Callback

Just had to set the displayrange calling imshow =P Thanks Analist.

That doesn't sound right. It looks like it's saying that it doesn't know what hf is. What is hf? If you want the slider value, do this:

% Get the value from the slider.  It might be a fractional number
sliderValue = get(handles.slider1, 'Value');
% Make sure it's an integer
sliceNumber = round(sliderValue);
if sliceNumber > 1 && sliceNumber <= size(I10, 3)
    imshow(I10(:,:, sliceNumber));
    caption = sprintf('Slice #%d', sliceNumber);
    title(caption, 'FontSize', 24);
end

Replace slider1 with whatever the actual tag of your slider is.
