Dear List,
I am using ConTeXt LMTX 2020.08.31 22:16. Consider the following MWE:
\starttext
\externalfigure[resolutionTest.png]
\stoptext
When comparing the output with ConTeXt MKIV, then the image size is
extremely small. gimp reports the resolution of resolutionTest.png as
71.984 DPI. Is this a bug? (I cannot reproduce the shrinkage with
hacker.png.)
Also, I noticed that the "resolution" key when applied as:
\externalfigure[resolutionTest.png][resolution=150]
has no effect. What is the meaning of this key?
Cheers,
Christoph

it's an image that has its resolution internally specified in meters and
that bit is commented (i probably had a good reason for that but for now
i'll uncomment it and add some safeguards for zero conversion values)
