IMAGEVIEWER

A GUI for viewing and interactively exploring image files.

Description

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).

• MATLAB release: MATLAB 7.3 (R2006b)
• Other requirements: Created in R2006b, but it should work in R14 or later.

The program currently does not work on certain images. A new version will be posted in the next couple of days. Thanks.

Jiro,
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?

[Luis Nieto]

Excellent job, works fine in R14 too.

[Tamir Suliman]

Thats a very nice job great

[Martin Fon]

This is a very good job. Could it be used for cropping?

[Edward Chao]

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!

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.

Tim Tam,
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.
