Decl.: void v_bez_fill( WORD handle, WORD count, WORD *xyarr, UBYTE *bezarr,
WORD *extent, WORD *totpts, WORD *totmoves );
Call: v_bez_fill( handle, count, xyarr, bezarr, extent, totpts, totmoves );
Variable Arguments Meaning
Input:
contrl[0] 9 v_bez_fill
contrl[1] n entries in ptsin
contrl[3] (n+1)/2 entries in intin
contrl[5] 13 signalisiert v_bez_fill
contrl[6] handle
ptsin[0..2n-1] xyarr[0..2n-1] Koordinaten
intin[0..(n+1)/2-1] bezarr[0..n-1] Punkttypen
Output:
contrl[2] 2 entries in ptsout
contrl[4] 6 entries in intout
intout[0] totpts number of points in the resulting polygon
intout[1] totmoves number of moves in the polygon
intout[2..5] reserved
ptsout[0..3] extent[0..3] coordinates of the bounding box
Meaning of the point-type flags:
bit 0: first point in a 4-point bezier curve (two anchor points and two
direction points). The last point of a bezier segment can be the
first point of the next bezier curve (or it can be a jump point).
bit 1: jump point - this point and the previous one will not be connected.
Bit 2-7 are reserved. If bit 0 is 0, v_bez_fill() works like v_fillarea() and
fills the area limited by a line between two points.
Note: The binding for this function has to swap the bytes in intin because unfortunately this function is compatible with PC-GEM. => bezarr[0] is the low byte of intin[0] bezarr[1] is the high byte of intin[0]...
