Question

Basically I want to get bezier control points from a ttf font and then draw them. I was basically wondering 2 things.

1. Does it return an array of points or is it more complex?
2. How can you tell the points of 1 contour from another ex: the letter O which has 2 contours?

Thanks

Found it:

The native buffer returned by GetGlyphOutline when GGO_NATIVE is specified is a glyph outline. A glyph outline is returned as a series of one or more contours defined by a TTPOLYGONHEADER structure followed by one or more curves. Each curve in the contour is defined by a TTPOLYCURVE structure followed by a number of POINTFX data points. POINTFX points are absolute positions, not relative moves. The starting point of a contour is given by the pfxStart member of the TTPOLYGONHEADER structure. The starting point of each curve is the last point of the previous curve or the starting point of the contour. The count of data points in a curve is stored in the cpfx member of TTPOLYCURVE structure. The size of each contour in the buffer, in bytes, is stored in the cb member of TTPOLYGONHEADER structure. Additional curve definitions are packed into the buffer following preceding curves and additional contours are packed into the buffer following preceding contours. The buffer contains as many contours as fit within the buffer returned by GetGlyphOutline.
