Detailed Description
Return array of indices defining a 2d subarea of a 2d array.
Given a – hypothetical – twodimensional array, "area" tells you, what indices you need to subscript a contiguous, twodimensional subarea. Returns 1-d indices.
For further information refer to the SLI documentation.
- Synopsis:
- source_width source_anchor_y source_anchor_x area_height area_width area_anchor_y area_anchor_x area -> [1d-indices]
- Parameters
-
source_width width of the (hypothetical) source array to be subscribed into source_anchor_y y position of the anchor point relative to ORIGIN OF THE SOURCE ARRAY source_anchor_x x position of the anchor point relative to ORIGIN OF THE SOURCE ARRAY area_height height of the subarea to be subscribed area_width width of the subarea to be subscribed area_anchor_y y position of the anchor point relative to ORIGIN OF THE SUBAREA area_anchor_x x position of the anchor point relative to ORIGIN OF THE SUBAREA
- Returns
- [1d-indices] flat integer array containing the indices that can be used to subscript the (hypothetical) source array in order to access the desired subarea.
