[NTG-context] Re: Strange behavior with anglestriped()

Hi, Fabrice, you have a problem with the definition of the path b: this path include q and b. To see this, replace your lines with : draw q anglestriped (1,45,2) withcolor cyan; draw b anglestriped (1,45,2) withcolor red; And you will see that the path b is drawn twice : once in red, once in cyan. So if you change your instructions to : draw q anglestriped (1,45,2) withcolor cyan; draw r anglestriped (1,45,2) withcolor cyan; This will correct the problem, because each path is now drawn only once. Fabrice.

Hi Otared, It's true that the color seems identical. Thanks. Fabrice

Hi Fabrice,

It seems to me the colors are the same, although they may appear different at first sight because the « with » of the lines are different (the width is larger in the lower rectangle).

I attach the PDF created with your code.

Best regards: Otared

Hi, I don't understand why the hatching of the two rectangles is not the same color. Thanks for your help. Fabrice
