Hi,I just stumbled across /* Please NOTE the different sign due to Y-axis flip */ start.x = centre.x + KiROUND( cosdecideg( radius, -StAngle ) ); start.y = centre.y + KiROUND( sindecideg( radius, -StAngle ) ); at common/plotters/plotter.cpp:164. Is that comment obsolete, or is there a bug here?
Neither. It is referring to the -stAngle. This flips the sin result sign but not the cos result. Perhaps it would be more clear if we used positive angle and flipped the sign in front of KiROUND but the outcome is the same.
