Hello There !
I had a look to the Outlines and specially to the FT_Outline structure. The
documentation is a bit weird for me :-) I know to have a Bezier curve we
needs a start point an eventual first control point,
an eventual second control point and an ending point.
The following text is snipped from the FT_Outline comment.
/* tags :: A pointer to an array of `n_points' chars, giving
*/
/* giving each outline point's type. If bit 0 is
*/
/* unset, the point is 'off' the curve, i.e. a Bezier
*/
/* control point, while it is `on' when set.
*/
/*
*/
/* Bit 1 is meaningful for `off' points only. If set,
*/
/* it indicates a third-order Bezier arc control point;
*/
/* and a second-order control point if unset.
*/
So let's say we have a vector starting at (0,0) to (100,100), 2 control
points (15,30) and (50,60)
Should the tags be set as here below ?
Tag 0 First bit = 0
Tag 1 First Bit = 1
Tag 2 Second bit = 1
Tag 3 First bit = 0
Thanks for any confirmation, or maybe contradiction :-)
