[pstricks] pst-slpe

[Manfred Braun]

Hi list,
When rotating an object that is shaded by  fillstyle=slpe,  the widths of the shading zones change with the rotation angle, see the minimal example below. Equidistant spacing appears only at angles 0 and 90 degrees. Is this intended? Is it possible to rotate an object keeping exactly the original shading pattern?
