overlay lifts image slightly

overlay lifts image slightly

[Pablo Rodríguez]

Dear list,

I have the following sample code (http://www.ousia.tk/overlay.pdf):

    \setuppapersize[S6]
    \usemodule[simplefonts][size=30pt]
    \definesimplefonttypeface[sfserif][Free Serif][scale=10]
    \setupmakeup[standard][align=middle]
    \starttext

    \startstandardmakeup
    \dontleavehmode\externalfigure[text-icon.pdf]
    [scale=5000]
    \stopstandardmakeup

    \startstandardmakeup
    \dontleavehmode\startoverlay
      {\externalfigure[text-icon.pdf]
    [scale=5000]}{\sfserif\color[red]{✘}}\stopoverlay\stopoverlay
    \stopstandardmakeup

    \stoptext

For some reason unknown to me, the overlay in the second slide has the
background image slightly lifted. All I have realized is that replacing
✘ with x shows no image lift, but I need ✘.

Is there any way to avoid this image lift?

Many thanks for your help,


Pablo

You have to increase the size of the image to mage it bigger than the ✘, you can do this
by wrapping it into a frame, e.g. \framed[frame=off,offset=1cm]{\externalfigure[…]}.

Many thanks for your gast reply, Wolfgang.

I‘m afraid that the frame itself lifts the image. Frame and overlay lift
the image also. PDF at http://ousia.tk/overlay.pdf.

I must be doing something wrong. Here is my code:

\setuppapersize[S6]
\setupinteraction[state=start]
\setupinteractionscreen[option=max]
\usemodule[simplefonts][size=30pt]
\setmainfont[KerkisSans]
\definesimplefonttypeface[sfserif][Free Serif][scale=10]
\setupmakeup[standard][align=middle]
\starttext

\startstandardmakeup
\dontleavehmode\externalfigure[Documents/Presentations/al-abordaje/text-icon.pdf]
[scale=5000]
\stopstandardmakeup

\startstandardmakeup
\dontleavehmode\framed[frame=on,offset=1cm]{\externalfigure[Documents/Presentations/al-abordaje/text-icon.pdf][scale=5000]}
\stopstandardmakeup

\startstandardmakeup
\dontleavehmode\startoverlay{\framed[frame=on,offset=1cm]{\externalfigure[Documents/Presentations/al-abordaje/text-icon.pdf][scale=5000]}}{\sfserif\color[red]{✘}}\stopoverlay\stopoverlay
\stopstandardmakeup

\stoptext

Many thanks for your help,

You have to write \smash[d]{\startoverlay …\stopoverlay} to get the same output with the overlay.

The \framed command isn’t necessary here.

You should also try to make minimal examples when possible only with default images and fonts.

Many thanks for your help, Wolfgang.
