Dear list,

I have the following sample:

\setuppapersize[A6]
\setuplayout[width=middle]
\starttext
\startmakeup[standard][align=center]
\dontleavehmode\externalfigure[cow][width=\textwidth]
\stopmakeup
\stoptext

How can I invert the colors in the external figure without having to
edit the image file?

Many thanks for your help,

You have to use the Adobe Reader to view the PDF.

\setupexternalfigure[location=default]

\starttext

\externalfigure[cow][width=\textwidth]

\startnegative
\externalfigure[cow][width=\textwidth]
\stopnegative

\startnegative
\externalfigure[cow][background=color,backgroundcolor=white,width=\textwidth]
\stopnegative

\stoptext
