GlyphsFilterOffsetCurve issue

Scripting
1 
@interface GlyphsFilterOffsetCurve : NSObject
+ (NSArray *)offsetPath:(GSPath *)path offsetX:(float)width offsetY:(float)height makeStroke:(bool)fill position:(float)pos;
@end

Is this definition incorrect? When I use it below, I cannot correctly bold the path, and the returned 'newPaths ’ is still the original path data.But it in python right.

 NSArray *newPaths = [NSClassFromString(@"GlyphsFilterOffsetCurve") offsetPath:path offsetX:30 offsetY:30 makeStroke:NO position:0.5];

Is that an open path?

3

no,that’s closed path.

The same one closed path in python code return 'newPaths ’ is right.

OffsetCurve = NSClassFromString("GlyphsFilterOffsetCurve")
newPaths = OffsetCurve.offsetPath_offsetX_offsetY_makeStroke_position_(path, 30, 30, False, 0.5)

Did I make a mistake in writing somewhere in objc code?

I just tried it and it works for me. Can you send me (in a private message it needed) the full code?

I sended a message to you.

The problem is the type definition of the GlyphsFilterOffsetCurve method:
if has to be like this:

@interface GlyphsFilterOffsetCurve : NSObject
+ (NSArray *)offsetPath:(GSPath *)path offsetX:(CGFloat)width offsetY:(CGFloat)height makeStroke:(bool)fill position:(float)pos;
@end

(there were float but it needs to be CGFloat or double)
