CImageView:Class Description

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()

Data Members

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.
AttachFromList	Attaches an Image window selected from a list and creates a new CImageView object for it.
GetViewPtr	Returns a pointer to the Mira image view window attached to the CImageView object.

Image Display Methods

Append	Appends the CImage object to the image view window's image set, making it the last image in the image set. Creates a new image view window if necessary.
Display	Creates a new image view window and displays a CImage object in it.
Insert	Inserts the CImage object into the image set at a specified index and displays the image. Creates a new window if necessary.

Image Set Operations

Count	Returns the number of images in the image set used by the image view window.
First	Indexes the image set to the first image.
GetImage	Creates and returns a CImage object for the view image at a specified index.
GetImagePtr	Returns a pointer to the image at a specified index of the image set. May also return the current image.
GetImageSet	Returns a copy of the CImageView's image set as a new CImageSet.
GetIndex	Returns the image set index of the CImage object in the image set of the image view window.
Last	Indexes the image set to the last image.
Next	Indexes the image set to the next image.
Prev	Indexes the image set to the previous image.
Remove	Removes the CImage from the image set and deletes it from memory.
SetIndex	Indexes the image set to a specified position.
SwapNext	Swaps the CImage object with the next image in the image set of the view window.
SwapPrev	Swaps the CImage object with the previous image in the image set of the view window.

Image Cursor

GetCursorPos	Returns the cursor center position in pixel coordinates.
GetCursorRect	Returns a CRect object that describes the image cursor.
SetCursorExtent	Sets the image cursor rectangle using (left, top, right, bottom) in pixel coordinates.
SetCursorHeight	Sets the height of the image cursor, in pixels.
SetCursorPos	Centers the image cursor to pixel coordinate x,y.
SetCursorPosWcs	Centers the image cursor at world coordinate x,y.
SetCursorRect	Sets the image cursor using a CRect object in pixel coordinates.
SetCursorStyle	Sets the image cursor style.
SetCursorWidth	Sets the width of the image cursor, in pixels.

Window Operations

CenterAt	Centers the image at pixel coordinate x,y.
CenterAtWcs	Centers the image at world coordinate x,y.
GetGraphSet	Returns the graph one/all flag for the image set of the image view window.
GetMeasureSet	Returns the measure one/all flag for the image set of the image view window.
GetProcessSet	Returns the process one/all flag for the image set of the image view window.
GetZoom	Returns the image zoom value.
GraphSet	Sets the graph one/all flag for the image set in the image view window.
MeasureSet	Sets the measure one/all flag for the image set in the image view window.
ProcessSet	Sets the process one/all flag for the image set in the image view window.
SetZoom	Sets the image zoom value.
Update	update the display after changing an image.
UpdateAll	update the display of all images in the window.
SetFlipFITS	Sets the option for flipping FITS image display.
GetFlipFITS	Gets the current state of the FITS flip flag.
GetPlotAvgMode	Returns the column/row averaging flag for making cursor plots.
SetPlotAvgMode	Sets the cursor plot averaging mode to mean, median, or sum.
