Exif_View division by Zero

Images from one of my cameras, a Casio QV-R61, generates the following message when adding the photos to the gallery and when they are displayed with the metadata selected:

Warning: Division by zero in /share/MD0_DATA/Web/piwigo/plugins/exif_view/main.inc.php on line 257

See example at http://jak.qcloudnas.com/piwigo/picture … category/1

It appears to be something to do with the exif_view plugin. Can anything be edited to resolve this please?

Thanks,

John

Re: Exif_View division by Zero

Examined the file main.inc.php and note that line 257 relates to the section dealing with Digital zoom. I always have digital zoom turned off so would rem'ing out the lines 254-257 prevent this error?

Re: Exif_View division by Zero

Well it was lines 254-258. I've rem'ed them out now and the error has gone away.

I presume the original file still needs investigating to see if this error can be prevented.

Re: Exif_View division by Zero

I've the same error

I've corrected the probleme with this code :

   // distance to subject
   if (!(strpos($key, 'SubjectDistance') === FALSE)) {
      $tokens = explode('/', $value);
      if (isset($tokens[1]))
      {
        if ($tokens[1] > 0)
        {
          $distance = $tokens[0]/$tokens[1];
        }
        else
        {
          $distance = $tokens[0];
        }
      }
      else
      { 
        $distance = $value;
      }
      return $distance.' m';
   }
