How to use method 'imread_from_blob' to read file from an in-memory blob?

[Javan Lu]

Hi Luis,

I need to read file from an in-memory blob, and there is a method named
'imread_from_blob' in the source code.

def imread_from_blob(blob, formatstr, as_grey=False, return_metadata=False):
'''
imdata = imread_from_blob(blob, formatstr, as_grey=False,
return_metadata={True})
imdata,metadata = imread_from_blob(blob, formatstr, as_grey={False},
return_metadata=True)

Read an image into a ndarray from an in-memory blob.

But this method was not memtioned in the API document.
Can I use this method to read file from an in-memory blob?

Yes, it should work.

You need to pass the format explicitly, though.
