Hello 9fans,
For me, jpg(1) can't display most jpeg images I have. So I made a go
program that convert a jpeg image from stdin to a png image to stdout.
Assume that Plan 9's png is not broken ;)
To test, go to https://thuychi.vn/anh.html
Of 50 images, Plan 9's jpg could only decode 3. The go library can
decode all of them.
I hope that there will be go image/plan9 and a draw library that works
on Plan 9 too... Replace the jpg(1) programs with the Go version!
bind /bin/jpgtopng.rc /bin/jpg, I think at least abaco don't need to
be modified.
