Member Function Documentation

- (void) saveImageAtURL:		(NSURL *)	url
withData:		(const void *const *const )	data
withPrecision:		(floating_precision_t)	precision
blackLevel:		(double)	black
whiteLevel:		(double)	white
withPlanes:		(u_short)	nPlanes
width:		(u_short)	w
lineWidth:		(u_short)	lineW
height:		(u_short)	h
metaData:		(NSDictionary *)	metaData

Save the image data in a file at the given URL. Simple as that ;o).

Parameters:

	url	The URL of the file to save
	data	An array of pointers to the image color planes
	precision	Wether the data buffer contains floats or doubles
	black	The value of the black level in the source image
	white	The value of the white level in the source image
	nPlanes	The number of color planes.
	w	Width of sample
	lineW	The number of samples in each line, as it can be larger than w there may be spare at the end of the lines.
	h	Height of sample
	metaData	The image meta data The pixels in the data are already scaled to 0.0 for black and 1.0 for white. The parameters
	black	and
	white	give the value they had in the source image before scaling ; this can be used to save the original value (for example in floating point FITS).
