Description Heath Caldwell (RETIRED) gentoo-dev 2007-08-06 19:42:46 UTC 
When I run gocr on an image that has pixels of all the same color, it dies with a floating point exception (division by zero).

Reproducible: Always

Steps to Reproduce:
1.  gocr -i /tmp/bad.pnm

Actual Results:  
# thresholdValue out of range 255..255, reset to 255
Floating point exception


Expected Results:  
Graceful exit.

Should this really be assigned to TeX herd?

Read the metadata.xml
Comment 5 Alexis Ballier gentoo-dev 2007-08-30 20:11:47 UTC 
nice, bug confirmed.
But, has this been sent upstream ? I'd prefer adding the patch as a backport rather than a fix as it changes the (bad) behavior of the program
Comment 6 Heath Caldwell (RETIRED) gentoo-dev 2007-08-30 20:44:49 UTC 
Submitted bug upstream.  Sorry for being lazy and hoping that someone else would do it.
Comment 7 Heath Caldwell (RETIRED) gentoo-dev 2009-04-21 16:26:40 UTC 
This has been fixed upstream in 0.47.
