CImageView Class
The CImageView class wraps a Mira image view
window that displays images. The Image View window uses an image
set to work with a group of images. This class encloses a pointer
to the view window and provides methods for displaying and
adjusting images and for working with the image cursor.
Executing Scripts from Image Windows
The Execute Script menu command may be used
to open and execute a script directly from a Mira Image Window.
When a script is executed from the Execute Script command,
it is automatically sent a CImageView object named
ParentImageView and a
CImage object named ParentImage. The ParentImageView is a CImageView object that
provides access to the window's
CImageSet member and other class members. The
ParentImage is a
CImage object attached to the current image in the
Image Window. You can use these names directly in the script or you
can rename them, like V =
ParentImageView andI =
ParentImage. A sample script call to be called from an Image
Window is provided named Execute from Image
Window test.lua.
