Dealing with string inputs about girder_worker

[jeffbaumes]

Your outputFileName structure has a few incorrect parts. png is not a valid format for type string, you should instead use 'format': 'text'. Also, the string value should be stored in the data field instead of the a field named text. So if you replace your declaration of outputFileName to this it should work properly:

outputFileName = {
        'type': 'string',
        'format': 'text',
        'data': "/home/vagrant/tangelo/tangelo_demo/proj/lennaimage.jpg"
}

Thanks. It worked!
So, is the "data" field the one that is expected all the time? I saw in the image blurring example, the "lenna" object had "url" instead of the "data".
How can I make the worker execute a method instead of the inline script. The document says that we can execute a script or a function. But it doesn't recognize the function when called from inside the script part.

This documentation should be made more clear, but the required fields for specifying input data is described here:

http://girder-worker.readthedocs.io/en/latest/api-docs.html#the-input-specification

Note a few other bits of information that aren't spelled out clearly in the docs:

• A type field is not required when sending an input to a task. Any supplied type will be ignored, since the task defines the required type of each input. However, the format field is required because the format is allowed to differ from the task spec. If a different format is supplied, the data will be auto-converted before running the task.
• The mode field is inferred in a few special cases. If there is a url field, the mode is assumed to be "http", and if there is a data field, the mode is assumed to be "inline".

So the following input specs are equivalent:

{
    'format': 'text',
    'data': 'hello'
}

{
    'mode': 'inline',
    'format': 'text',
    'data': 'hello'
}

As well as the following:

{
    'format': 'png',
    'url': 'https://upload.wikimedia.org/wikipedia/en/2/24/Lenna.png'
}

{
    'mode': 'http',
    'format': 'png',
    'url': 'https://upload.wikimedia.org/wikipedia/en/2/24/Lenna.png'
}

I'll submit a PR to get this documentation in there.

That's cool. Thanks!
