#48 zbarimg - read from stdin

[Bernd Zeimetz]

Forwarded from http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=602954

currently, if i run

zbarimg foo.png

it does what i expect.

but if i do:

zbarimg - < foo.png

it fails, saying "ERROR: specify image file(s) to scan"

accepting data on stdin makes it much easier to hook zbarimg together
with other tools in shell pipelines. this would be a nice feature to
have.

This feature already exists; zbarimg accepts data on stdin using the ImageMagick syntax, eg:

zbarimg PNG:- < foo.png
convert foo.png -blur 0 MIFF:- | zbarimg MIFF:-

I also made a quick fix to allow the autodetected syntax you are expecting (applied to hg, rev 8d7f0b03b96b). Let me know if you see any problems with it...

Thanks for forwarding this request!

i can confirm that the hg revision in question makes things WorkForMe™ as i expect/hope (i applied it against the 0.10+doc-4 source in debian).

Thanks for the fix!
