Re: [NTG-context] Gradient fill in embedded pdf disappear in externalfigure (on regular pages)
How odd; Then it must be related to my viewer here ... I was just surprised to literally see two different outcomes with the \startTEXpage and without. Maybe it has to do with some sort of "nesting" in the PDF that is not handled correctly at the PDF viewer's end. I'll test again on a different machine (and with the printing company) when I'm back to work.

[NTG-context] Gradient fill in embedded pdf disappear in externalfigure (on regular pages)
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!
Benjamin
