OK - well, my scheme knowledge is not enough :-( Here is the relevant
section of the code:
(define (spline)
(let* ((a (cons-array 8 'byte)))
(set-pt a 0 0 0)
(set-pt a 1 63 60)
(set-pt a 2 191 194)
(set-pt a 3 255 255)
a))
(define (set-pt a index x y)
(prog1
(aset a (* index 2) x)
(aset a (+ (* index 2) 1) y)))
(gimp-curves-spline inDrw 0 8 (spline))
Just changing the procedure name in the last line to
gimp-drawable-curves-spline is not enough. If I understand correctly, the
program allocates an array of 8 bytes where 8 integer values (0,0; 63,60;
191,194; 155.255) are stored. The memory to be allocated should be adequate
for 8 floating point values (8 * 32 bytes?), and the values stored there. Is
set-pt adequate? Or intended for integer values only? May somebody help me?
