image/jpeg: "fill bytes" not supported

[gopherbot]

by jsummers3456:

In a JPEG file, extra 0xff bytes immediately preceding a marker are called "fill
bytes", and are supposed to be ignored. Go fails to decode any file that contains
fill bytes.

Test case: Use jpeg.Decode() to read the attached file.

Expected result: The image is decoded successfully.

Actual result: Error: "unsupported JPEG feature: unknown marker"

Can you describe how that test image was generated?

Comment 3 by jsummers3456:

I don't know of any applications that write fill bytes, if that's what you're asking. I
created it artificially.
