Missing documentation on Errors

[frnco]

How to properly catch errors from Resizer? Are all errors documented?

Hi @ellahn,
You should add an "error" event handler on the stream itself.
In case of error, you will receive a message related to the type of error.

Unfortunately not all errors are documented, but they can roughly categorised as follows:

• stream errors (e.g.: timeouts)
• errors due to the execution of an external process (e.g.: graphicsmagick not found, process killed)
• errors specific to graphicsmagick (e.g.: unsupported file format). In these cases graphicsmagick exit code is reported in the error message.

This project has been extracted from https://github.com/blomming/image-server there you can see an usage example.

Hope this help,
let me know if you have any problem.

I've had a case where the "finish" event was emmited on the receiver stream, but later an error popped up - GM exited with code 1.
If you want to be sure that no error will be emitted anymore, wait not only for the "finish" event, but also for the "exit" event on the stream.

Leaving this just in case someone has the same problem as me.
