Hi all,
I have been having problems generating png files on a Mac running OS X 10.6.8.
Here's a simple example
> png("foo.png", type = "cairo"); plot(1:10); dev.off();
null device
1
libpng warning: Application built with libpng-1.2.26 but running with 1.5.2
The resultant file is of size 0 Kb.
Is this the proper place to report this issue? Or should this
be reported to r-sig-mac?
If I run
> png("foo.png"); plot(1:10); dev.off();
null device
1
I get a 16 Kb file with the appropriate plot. (Odd, since the default type is
"cairo".)
Whenever I see the libpng warning, I end up with a 0 Kb file.
Details of R session below.
Regards
Steve McKinney
