_imageapi_imagemagick_convert_exec() currently considers that anything that convert outputs in stderr is an error that should be reported (in red) to any users, including anonymous.

That's wrong for two reasons:

  • convert outputs warning to stderr in some conditions, for example when parsing non-totally-compliant images. Those warnings don't result in the conversion failing, and they should not be displayed
  • displaying error messages to every visitors, without a way to remove them, is a bad practice

Here is what I suggest:

  • Rely solely on the return code to decide if stderr is an error or not
  • If we identified an imagemagick error, throw a PHP error. This error will be then caught by Drupal error handler, that will log it to watchdog and eventually display it to the user if configured to do so.

I got the condition upside down in this patch, sorry (last minute cleanups...).

DamZ:

That patch looks good, and solves the issue. I've attached an alternative, which does two things.

  1. It checks to make sure we have an error to report
  2. It adds the error code to the message

Here is another patch, which cleans this up a bit more.

We always report the error code, however we add some logic to print the error message, if it exists.

+        trigger_error(t("ImageMagick reported error code !code,\nMessage:\n!error", array('!code' => $return_code, '!error' => $errors)), E_USER_ERROR);

Seems like there should either be a period or Message should be lowercase.
