[Rd] tcltk image reading problem (on a mac?): [tcl] encountered an unsupported criticial chunk type "eXIf"
I don't know what has changed with Catalina
But I just tried my tk console from the shell command tkcon
And got the following error.
Here is my shell:
$ tkcon
dyld: Library not loaded: /usr/local/lib:/opt/X11/lib/libtk8.6.dylib
Referenced from: /usr/local/bin/wish
Reason: image not found
Abort trap: 6
I don't know whether this is a red herring or not, but the
Console fails to boot.
John does it work for you?
Not sure whether Python has the same trouble. Kind of old info at

Dear Wayne and Peter,
FWIW, I observe exactly the same problem in Catalina. The error and my
session info:
-------- snip --------

Error in structure(.External(.C_dotTclObjv, objv), class =
"tclObj") :

[Rd] tcltk image reading problem (on a mac?): [tcl] encountered an unsupported criticial chunk type "eXIf"
Wayne, that one is unrelated, but interesting - you can fix it with sudo install_name_tool -change \ /usr/local/lib:/opt/X11/lib/libtk8.6.dylib \ /usr/local/lib/libtk8.6.dylib \ /usr/local/bin/wish8.6 There is a bug in tcltk with IDs on the libraries which I have worked-around for R, but not for wish. Back to the original question - do you have any example of a file that doesn't work so I could test? Exif chunks are fairly rare in PNG and are a more late extension so I couldn't find any examples.

[Rd] tcltk image reading problem (on a mac?): [tcl] encountered an unsupported criticial chunk type "eXIf"
Some googling suggests that this is an issue in tcltk which doesn't support
png files with Exif tags. Are you sure this ever worked? This doesn't seem
to be related to the macOS version since it's a feature tcltk, not the
system.
I had no issue using the png package, so you could simply remove any offending
chunks with
writePNG("test.png",readPNG("exIf.png", TRUE,TRUE))
then the output work with tcltk.
Cheers,
Simon
