Hi Ralph,
I don’t see any pixels in the PDF file when I typeset your code snipet (on MacOS 11.7.10). Here is what I get. No problems on windows on chrome-os either. Mikael S and I checked it on his linux box and one can indeed see anti aliasing when taking a screen dump (depends on resolution).
So it's a linux rendering issue when taking dumps. That said: we can't do anything about it. Using rules (traditional approach) is pretty bad in screen dumps and even regular rendering, depending on zoom; there one has interaction between the font rendering and other graphic elements (rules). Btw, vertical extensibles are not different (take the bracket which has similar constructs). Interesting is that it is straight blob connections that can show these occasional gray pixels and it only seems to happen with a little overlap. Kind of a bug we think. Hans ps. One reason when I always use (x)ubuntu when i have to use a linux desktop is that it always was set up right wrt rendering fonts and anti aliasing. I might need to check that. ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
