CImageView:new

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.

Usage

Construction

Object = CImageView:new()

Destruction

Object:delete()

properties

ptr

A pointer to the Mira image view window. This pointer is nil if no image view window has been attached.

Note: It is not wise to work directly with ptr. Instead, refer to ptr using the GetViewPtr method.

Methods

Construction

new

Creates a new CImageView object. This is the global script counterpart of the GetParent method.

delete

Deletes the CImageView object.

Attach

Attaches the top-most window (an Image window) to the script and creates a new CImageView object for it.

NOTE: When using this method, make the target image window the top-most window and run the script using the Script Manager or the [ ! ] button on the main toolbar, not the [ ! ] button in the script editor window.
