Image Display with Mouse-Description

From IGSTK

The purpose of this example is to demonstrate using combination of packages from the IGstk into a single application. This application would facilitate the following:

• loading of an image data in any of the ITK-supported formats,

• displaying individual slices of the data, one at a time, with means to choose a slice for display (arbitrary or sequential).
• record voxel co-ordinates of the last point clicked by the mouse on the image display.

A detailed user story is as follows:

• This demo application opens up a window consisting of the following:
  • a top menu bar.
  • an image display area.
  • text boxes to display voxel co-ordinates of the last point on the image that mouse was clicked upon.

• The top menu bar of the window has options for
  • choosing the image data from the directory structure local to the machine,
  • safely exiting from the application.

• When no image data is loaded,
  • The image display area is blank,
  • option(s) for slice selection is grayed,
  • no action is taken on a mouse movement/click.

• When a new image is read,
  • the middle slice of the data set is displayed in the image window,
  • the slice selector is positioned and set appropriately. Care should be built in that only possible slices for display may be selected.
  • mouse click recording is activated, with text boxes displaying voxel co-ordinates of last clicked point initialised with zeros.
