In lorweiuk/CREx: Run behavioral experiments from R.

Draws a filled circle with limited precision.

Description

Draws a filled circle defined in circle_list to rendering target. Circle is defined in terms of center point (centerx, centery) and radius. Precision is set by user (n_points). Precision determines how many line segments the circle's outline consists of.

Usage

CRfill_circle_n(graphics_list, circle_list, n_points, status = NULL)

Arguments

graphics_list	List containing pointers to window, renderer etc. created with CRopen.
circle_list	List defining circle, containing elements centerx and centery as well as radius.
n_points	Positive integer setting precision of circle.
status	Optional list status with elements value and message to retrieve warnings and error messages.

Details

CRfill_circle_n divides circle into trapezoids and fills those line-by-line.
