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, Pablo -- http://www.ousia.tk
