Artifacts close to start/end points #16

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 

Freetype-go generates artifacts close to start and end path points,
output differs from Freetype-C.

Font is automatically converted from C to Q by FontForge, no problems detected.
Rearanged canonical start point to leftmost on the contour produces expected 
output.

Reduced artifact example mapped to "1", and correct to "0" with start on the 
leftmost contour point.
This is tolerated by freetype-C.

Aforementioned problem is due to freetype-go assumes first path point as 
on-curve one.

Please see my proposed rewrite of drawContour() in 
code.google.com/p/freetype-go/freetype/freetype.go, it is almost camelcased 
FT_Decompose_Curve function.
It can be tested with attached font for on-on, on-off, off-on and off-off 
first-last curve points, mapped to 0-3.
