IMAGEVIEWER Interactively pan and zoom images on the computer.
IMAGEVIEWER starts a GUI for opening image files and interactive panning and zooming.
IMAGEVIEWER(DIRNAME) starts the GUI with DIRNAME as the initial directory.
The GUI allows you to navigate through your computer and quickly view image files. It also allows you to interactively explore your images by panning (clicking and drag), zooming (right-click and drag), and centering view (double-clicking).
This is implemented using MATLAB Classes. It requires MATLAB R2008a or newer.
Excellent tool. It works for my Matlab 2013a WIN64 BIT. I have a question: I want to add displaying the boundingboc and detected areas on the image. Can this be compiled as a matlab standalone application?
Attempted to install APP and run in MATLAB Version 22.214.171.1244 (R2013a)...
GUI starts up and allows a directory selection, but causes MATLAB to crash non-gracefully shortly after the list of files is populated.
Has anyone else experienced this behavior and is there a preventative fix?
Thank you ! ImageViewer is an excellent GUI implemented using matlab classes !
I try to use interactive panning and zooming with the matlab preview fcn of live video data.
I coded that :
% --- Executes on button press in Preview.
camobj = obj.camobj;
vidRes = get(camobj, 'VideoResolution');
imWidth = vidRes(1);
imHeight = vidRes(2);
nBands = get(camobj, 'NumberOfBands');
% create an empty image container and show it on axPreview
iH = image(zeros(imHeight,imWidth, nBands), 'parent', obj.handles.ImageAxes);
Zoom seems to work on live video data, but pan doesn't work.
Could you help me?
not so much handy enough,try to add some extra features.:D
I didn't code it so that you can extract the selected file name through the handles. Also, I made the GUI "HanldeVisibiltiy" to "off" on purpose so that it can't be accessed from the Command Window. That's why "gcf" and "gca" doesn't see it.
If you need to access the inner workings, I suggest you take a look inside the m-code. When I create the initial figure, I set the "HandleVisibility". You can change that to "on". Also, there's a place in the code that I extract the file name from the list box.
How can one retrieve the name of the image file that the user has selected ?
I've tried returning then querying various handles, but can't get any approach to work.
Also gcf and gca don't seem to work with the viewer - when issued they create new figures / axes.
Excellent examples of using the object callbacks (ButtonDownFcn, WindowButtonMotionFcn, WindowButtonUpFcn) for panning and zooming. I was looking for some good examples for a long time. Thank you very much!
This is a very good job. Could it be used for cropping?
Thats a very nice job great
Excellent job, works fine in R14 too.
It works very well with R14SP1 - I am very impressed. Thank you!
Very soon I do need only Matlab - when is the Office tool available to replace Word?
The program currently does not work on certain images. A new version will be posted in the next couple of days. Thanks.
Updated to include an App file for R2012b
Implemented in MATLAB Classes
Copyright update. Added scroll wheel zoom.
Cosmetic changes to the GUI. A better TIMER management.
Bug fix for image centering feature. Also allow the window to be resized (without distortion of components)
Bug fixes. Make sure it works with various image types.
It actually works in R14 or later.
