\setupbackend[space=yes] and hz

\setupbackend[space=yes] and hz

[Pablo Rodriguez]

Hi Hans,

I have the following sample:

  \definefontfeature
    [default]
    [default]
    [expansion=quality]
  \setupalign
    [hz]

  \setuppapersize[A6]
  \setupbodyfont[pagella]
  \setupbackend [space=yes]
  \starttext
    \input zapf
  \stoptext

Using SumatraPDF-3.1.2 and current latest (from 2021.05.21 15:07),
spacing is only right when I disable font expansion.

Would it be possible that spacing be the same with and without font
expansion?

Many thanks for your help,

Pablo

not sure what you mean but using hz without stretch (and/or tolerance) 
makes no sense

   \setupalign
     [hz,stretch] % maybe also add tolerant

also, you should update your sumatra (I have 3.3 and am not going to 
waste time on older versions).

It doesn’t make any difference in the text spacing (searching and
copying) in the minimal sample.

I wish I could. PDF annotations are a mess in MuPDF (this affects
versions from 3.2).

PDF annotations in SumatraPDF-3.3 are huge, even preventing the text
from being readable. And they are always printed (since all contain "/F
4"), no matter that no appearance dictionary allows to print them.

I have already discussed that with people from Artifex, but it seems
that they won’t change their mind about this.

It would be helpful that PDF annotations in ConTeXt with no associated
appearance dictionary could have "/F 0" (so that MuPDF doesn’t print them).

Many thanks for your help,

Pablo
