Typedef Documentation

typedef unsigned* ImageIndexVector

an ImageIndexVector is a vector of indices into a operaFITSImage, the index values start from 1 and the vector is null terminated.

typedef float** Matrix

a Matrix is a 2D image array, the first dimension is y, and the second is x. C libraries may make use of this data structure for simple indexing in to an image. where C libraries could not access the operFITSImage class in the same way.

Function Documentation

unsigned veclen

(

ImageIndexVector

v

)

since ImageIndexVectors are null-terminated, we emulate strlen.

veclen

Parameters:

v	- ImageIndexVector*

Returns:

unsigned

ImageIndexVector where	(	operaFITSImage *	b,
		unsigned *	count
	)

where function - return a vector of the same size .

where

Parameters:

b	- operaFITSImage*
count	- count of 1's

Note:

usage: operaFITSImage a = a.where(b>0.0, &count); returns vector of 1s and 0's and count of 1's

Returns:

unsigned *

where function - return a vector of the same size .

where

Parameters:

b	- operaFITSImage*
count	- count of 1's

Returns:

operaFITSImage&
