CImageView:GetFlipFITS

The GetFlipFITS method retrieves the state of the flag that controls whether FITS format images are displayed in the traditional sense, with row number increasing upward.

Syntax

bTrue = CImageView:GetFlipFITS()

where

bTrue is the state of the FITS flip flag.

This method returns true if the CImageView is configured to display FITS images in the nontraditional, flipped sense.

The CImageView class defaults to displaying FITS images in the tradition sense—"unflipped", with row number increasing upward. Use this method to check the protocol before displaying the image. Also see the SetFlipFITS method and the topic FITS Image Orientation.

Example

The following script saves the FITS flip flag before displaying the image, then resets it afterward:

V = CImageView:new()	-- create a CImageView
I = CImage:new()	-- create a CImage
I:Open(sPath)	-- load a FITS format image from a file
bFlipped = V:GetFlipFITS()	-- retrieve the flag and save it
V:SetFlipFITS(true)	-- change to "flipped" for this image
V:Display(I)	-- display the image
V:SetFlipFITS( bFlipped )	-- restore the FITS flip flag
