Thanks everyone for getting a solution.
Brian's solution works for me too.
Thanks again!!

There are several png() devices for R. The default on macOS is to use
Quartz, and that depends on macOS system functions so might well have
changed with Mojave -> Catalina.
As a workaround, try e.g. png(type='cairo'). E.g.
fname <- file.path(tempdir(), "Rplot.png")
png(filename = fname, width = 500, height = 500, type="cairo")
hist(rnorm(20))
dev.off()
library(tcltk)
tkimage.create("photo", file = fname)
works for me on Catalina.

Re: [Rd] tcltk image reading problem (on a mac?): [tcl] encountered an unsupported criticial chunk type "eXIf"
Ah, thanks, Brian, so the issue is that Catalina is now embedding Exif tags
while previous versions didn’t. Tcltk never supported them, but it only came up
now as Catalina is generating them. I’ll check if tcltk has ever fixed it.

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.
The code in Wayne's original message (copied below) generated the offending
file:
library(tcltk)
fname <- "Rplot.png"
png(filename = fname, width = 500, height = 500)
hist(rnorm(20))
dev.off()
tkimage.create("photo", file = fname)

Re: [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

Re: [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.
Thanks,
Simon

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:

I don't know whether this is a red herring or not, but the

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") :

This is from RStudio but I see the same thing in the R.app.
I hope this is of some help,

Re: [Rd] tcltk image reading problem (on a mac?): [tcl] encountered an unsupported criticial chunk type "eXIf"
Yes.
I seem to be picking up
8.6
I should have noted that.
Use to work for me too in Mojave.
I have the sneaky feeling that Catalina is the problem.

Happy enough for me on Mojave.
On the off chance that you are picking up an old Tcl, do you see this?

[Rd] tcltk image reading problem (on a mac?): [tcl] encountered an unsupported criticial chunk type "eXIf"
Hello everyone
I am not sure when this appeared
(sometime post R 3.5.0 and after I switched to Mac OS Catalina).
I do not think it happens on all platforms (e.g. seems to work on windows).
But it seems that
tkimage.create()
no longer works on a Mac for all png files.
(It does work for *some* old png files I have on disk but I have not been able
to determine what is different about the ones that work)
Any help would be appreciated.
