> TiffReader.readDirectories() fails on EXIF data
> -----------------------------------------------
>
> Key: IMAGING-258
> URL: https://issues.apache.org/jira/browse/IMAGING-258
> Project: Commons Imaging
> Issue Type: Bug
> Components: Format: TIFF
> Affects Versions: 1.0-alpha1
> Reporter: Gary Lucas
> Assignee: Bruno P. Kinoshita
> Priority: Minor
> Fix For: 1.0-alpha2
>
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> When reading a TIFF directory that contains an EXIF sub directory, the
> TiffReader class throws an ImageReadException stating that "ExifOffset has
> incorrect type IFD".
> This exception occurs in the TiffReader.readDirectories() call which attempts
> to read all IFD's (directories) in a TIFF file. It can be avoided by calling
> TiffReader.readFirstDirectory(). Of course, if you do that, you will not be
> able to access the EXIF elements.
> This happens when accessing the TIFF element with TIFF Tag 0x8769. I suspect
> that it could also happen with TIFF files containing GPS extensions, Tag
> 0x8825.
> I've gotten this issue with GeoTIFF files from a couple of different sources.
> The one I'd recommend for testing would be the public-domain "Natural Earth
> Data" medium-size Cross-blended Hypsometric Tints file at
> [https://www.naturalearthdata.com/downloads/10m-raster-data/10m-cross-blend-hypso/]
> I am not experienced with the EXIF sub-directory specification and do not yet
> have a good sense of what the level of effort for a fix would be.
