FITS 1.5.0 - Unable to identify tif files

[Satyam Reddy]

I am trying to process tif,tiff files using the new versions. It's only being identified by only Exiftool and others won't work.

sample output.

<identification status="SINGLE_RESULT">

    <identity format="TIFF EXIF" mimetype="image/tiff" toolname="FITS" toolversion="1.4.1">

      <tool toolname="Exiftool" toolversion="11.14" />

    </identity>

  </identification>

Hello,

Two thoughts:

1) Without having the TIFF file to analyze, here is my guess as to why only Exiftool is providing output: As shown in the <identity> element in your sample output, there is format="TIFF EXIF". Other tools may have identified the format as "TIFF" but without "EXIF included". Since TIFF EXIF is a more specific format than only TIFF, only the output for the more specific type is included in the FITS output. A way to test this is to find the 'fits.xml' file within the 'xml' directory of your FITS deployment and comment out the line that begins with "<tool class="edu.harvard.hul.ois.fits.tools.exiftool.Exiftool"... " and process the TIFF file again to see if now there is output from other tools.

2) It looks like you are using FITS version 1.4.1, not 1.5.0 as seen at the end of the <identity...  line of your sample output.

Looking forward to seeing your results.

Hi David - Thanks for your inputs. I have tried commenting out the Exiftool and processed the TIFF file again. The format of the file was correctly identified by all the required tools except Exif. Here are the results.

Additionally, I ran the TIFF file directly with Exif tool and it correctly identifies the format. Is it a configuration issue in FITS?

[David Neiman]

Hi Satyam,

Yes, it's configuration within FITS that is causing this. This is a result of the needs of the Harvard library where we maintain FITS and process files for the library. You are welcome to play around with an Exiftool configuration file that will affect the 'format' attribute output but we will not be able to provide much additional support beyond that.

Look at the file within the the FITS deployment in xml/exiftool/exiftool_common_to_fits.xslt.

First try commenting out lines 101 through 103 as follows and examine your resuls:

<!--                     <xsl:when test="not(string-length($exifByteOrder) = 0) and not(exiftool/FileType = 'JP2')"> -->
<!--                         <xsl:value-of select="concat(exiftool/FileType,' EXIF')" /> -->
<!--                     </xsl:when> -->

Then you could try commenting out, in the same file, lines 95 through 97:

<!--                     <xsl:when test="not(string-length($exif) = 0) and not(exiftool/FileType = 'JP2')"> -->
<!--                         <xsl:value-of select="concat(exiftool/FileType,' EXIF')" /> -->
<!--                     </xsl:when> -->

Good luck with experimenting,

David

It worked by commenting lines 101 through 103. Thanks for your help and support.
