layers and \llap

layers and \llap

[Pablo Rodriguez]

Hi Hans,

this comes from a previous message about an issue with \llap and layers.

Here is the sample:

    \defineviewerlayer[print][state=stop,printable=yes]
    \defineviewerlayer[view][state=start,printable=no]

    \starttext
    \startviewerlayer[view]\color[red]{\TeX}\stopviewerlayer%
    \startviewerlayer[print]\llap{\ConTeXt}\stopviewerlayer%

    \input zapf
    \stoptext

If the layer with \llap is placed last, disabling the view layer
disables all the text.

Everything works fine if the layer with \llap is placed first.

I guess this might be a bug.

Many thanks for your help,

Pablo

Works for me on both Evince and Foxit Reader.  I can't test Adobe because I'm
on Linux.

Try also \dontleavehmode\llap{\ConTeXt} because \llap by itself does not start
a paragraph.

Cheers,
Henri

Hi Henri,

many thanks for your reply.

This is really weird, since I cannot make it work, either with Acrobat
in Windows nor in Evince or Acrobat in Linux.

I’m using latest beta from 2019.11.14 17:07 (either MkIV or MkXL). Which
beta are you using?

Many thanks for your help,

Pablo

Hi Pablo,

I can reproduce the issue on MacOS on Acrobat Reader, and also on Adobe Acrobat Pro.
In fact turning off any last viewerlayer makes the text disappear.

Best regards: OK
