Benjamin Douglas updated TIKA-570:
----------------------------------
Attachment: TIKA-570.patch
I am attaching a patch that encodes the "BM" prefix, the color planes
signature, and the possible bit count values in tika-mimetypes.xml. I believe
that since we are checking for the "BM" magic, this should not conflict with
any OS/2 variations, since they have different magic values, like "BA", "CI",
etc.
This patch adds the original text file to the test document set and confirms in
the unit test that it is not detected as a bitmap.
> If this is a BMP, my name is horatio alger
