skxray.core.img_to_relative_xyi¶

skxray.core.img_to_relative_xyi(img, cx, cy, pixel_size_x=None, pixel_size_y=None)¶

Convert the 2D image to a list of x y I coordinates where x == x_img - detector_center[0] and y == y_img - detector_center[1]

Parameters:	img: `ndarray` : 2D image cx : float Image center in the x direction cy : float Image center in the y direction pixel_size_x : float, optional Pixel size in x pixel_size_y : float, optional Pixel size in y **kwargs: dict : Bucket for extra parameters in an unpacked dictionary
Returns:	x : ndarray x-coordinate of pixel. shape (N, ) y : ndarray y-coordinate of pixel. shape (N, ) I : ndarray intensity of pixel. shape (N, )
