Add method Intervals.positions( Interval ) to allow localizing LoopBuilder loops.#279
Conversation
The method is the same as the already existing method
Localizables.randomAccessibleInterval() but has a much
better name.
This method allows to write LoopBuilder loops, that
use the pixel coordinates.
LoopBuilder.setImages( Intervals.positions( image ), image ).forEachPixel(
( position, pixel ) -> {
int x = position.getIntPosition( 0 );
int y = position.getIntPosition( 1 );
pixel.set( x * x + y * y );
}
)

It's hard to get pixel positions in a LoopBuilder loop. This PR implements the solution (1) suggested here #273 (comment).
The method
Intervals.positions(Interval)returns an image where each pixel value equals the position of the pixel. (The new method does the same as the existing methodLocalizables.randomAccessibleInterval(Interval), but the name is much nicer.)This allows the get pixel positions in
LoopBuilder:
