Comment #104 on issue 2658 by [email protected]: wrong stem rendering
(inconsistent thickness)
http://code.google.com/p/lilypond/issues/detail?id=2658
What about actually changing the stems from rounded rectangles to lines?
Janek, you can easily try that, and didn't we try that a few months ago?
I asked someone with the affected PDF previewer to try replacing
round-filled-box in output-ps.scm with something that draws a single line
for boxes where the lines along the sides overlap. You don't need to
recompile to try this.
Maybe I should have put in a fudge factor, since stems are near-exactly two
linewidths thick, by default.
(define (round-filled-box left right bottom top blotdiam)
(let* ((halfblot (/ blotdiam 2))
(y (- halfblot bottom))
(height (- top (+ halfblot y)))
;; If the lines along the sides of the box (nearly) overlap
;; then use one line of the width of the box
(linewidth (if (>= (* 2.2 blotdiam) ;; fudge 2 to 2.2
(+ left right))
(+ left right)
blotdiam))
(halfwidth (/ linewidth 2))
(x (- halfwidth left))
(width (- right (+ halfwidth x))))
(ly:format "~4l draw_round_box"
(list width height x y linewidth))))
