Description leonardo 2006-08-24 01:56:16 UTC

It should adjust the stroke width to integral pixels. Now it does only for 
vertical and horizontal strokes. Applying fill_adjust over an unadjusted width 
gives a variable visible width along the line.

Test case

The problem still occurs in the current master branch.

"true setstrokeadjust" should keep the width of a line constant, i.e. the left and the right side of the line should change at the same position along the line. Ghostscript changes every side independently, creating a variation of thickness of 1 pixel along the line.

It appears that Ghostscript does not adjust the width of slanted lines at all.
