Hello list,

I have noticed that some gradients get lost when embedding an external figure from a pdf (Preview and Acrobat DC and in printer), although the original pdf works fine for me.

It seems to occur with color-to-color gradients (but not all), but not with color-to-alpha ones.

While preparing a MWE, I further realized that I get the correct output when between \startTEXpage ... \stopTEXpage

\starttext

Embedded via \type{\externalfigure}

PNG

\externalfigure[drawing.png][width=72.631mm,height=21.702mm]

\blank[big]

PDF

\externalfigure[drawing.pdf]

\startTEXpage  % this "works"
Embedded via \type{\externalfigure} in \type{\startTEXpage ... \stopTEXpage}

PNG

\externalfigure[drawing.png][width=72.631mm,height=21.702mm]

\blank[big]

PDF

\externalfigure[drawing.pdf]
\stopTEXpage

\stoptext

Any hints what I would need to change in order to get the gradients also in non-TEX-page mode?

I attach the two original files and the output produced with this MWE.

Thanks!
