Hi , I am a new user of the font box library . I need to draw bezier curves using data from the glyph table . Class GlyfSimpleDescript has a method called getFlags(pointIndex) which returns the flags at the coordinate point index pointed to by the value of pointIndex.But I get values like 33 , 54 etc . Please tell me what is the meaning of these flags . The API documentation have so such details available .The ttfdump files have a section like this Flags ----- 0: On 1: XDual Off 2: Off 3: YDual On 4: X-Short On 5: YDual Off 6: Off 7: XDual On 8: YDual On 9: XDual Off 10: Off 11: YDual On 12: XDual Y-Short On 13: YDual Off 14: Off 15: XDual On 16: On 17: YDual X-Short On I need to check whether the point being draw on the screen is on or off the curve . We have a GlyfSimpleDescript ON_CURVE constant in the library which only returns 1 . I need to find out the on/off curve status for each of the points , which I am not being able to find out at present .
Those constants represent the number of the bit within the flag value. In your case you need to check the following boolean onCurve = (flagValue & GlyfDescript.ON_CURVE) != 0 HTH Andreas
Writing this mail after a lot of search , if I receive a reply I wish to share it with all the other users . Please kindly advice.
