TIFF to TIFF convert doesn't keep custom tag

Post by arnoques » 2012-10-03T17:47:01-07:00

I'm re-posting this question as a bug since it looks like it isn't the intended behavior.

I'm trying to compress many tiff images to save some space. I'm using

Code: Select all

convert Q32_cm4989.tif -compress Zip Q32_cm4989_zip.tif
with ImageMagick 6.7.7-10 2012-08-27 Q16 (Features: OpenMP) in Debian testing.

The problem is that convert strips the proprietary tag 34118 (which I need, since it has lots of info). The original image can be downloaded here. I'm posting all the information I can about the images.

Code: Select all

Re: TIFF to TIFF convert doesn't keep custom tag

We can reproduce the problem you posted and have a patch in ImageMagick 6.7.9-10 Beta available by sometime tomorrow. Thanks.

Sorry to up this old thread, but I have the same problem and cannot find aversion of ImageMagick that would preserve unkown tags.

The relevant tiffinfo is :

Code: Select all

and after running

convert 17_000737870_005092700_17.tif -compress zip 17.tif
The tags are removed :

I have tried with 6.7.9-10 and 6.8.0-10 (since magick reported that the bug was fixed in 6.7.9-10 beta).
I have also tried with the latest 6.x version (6.9.10-13 as of now).
All versions show the same behavior and strip unknown tags.

But isn't this a known tag ? identify shows the tag name.
The problem is with custom tags ("unknown field with tag" warning during conversion, "Tag 33550" in identify).

Warnings like that are just warning that IM does not understand custom TAGs. I do not think that they get removed. At least in my case it did not happen. If you do not want to see the warnings, add -quiet to your command line right after convert/magick depending upon your version.

Yes I know about quiet, but warnings are not the problem here.
The tags are removed in my case, as shown by the identify I posted for the input and output tiffs.

You mean that you have the warnings about unkown tags and still have them in the output ?

Yes. Perhaps your version of ImageMagick is prior to any bug fix for that issue mentioned above. I suggest you upgrade your ImageMagick and perhaps libtiff. What tag is in your input that is not in your output? Post an example TIFF image that shows this problem to you, so we can test with it.

As I mentioned in my post, I tried with different versions, including the latest 7.x and latest 6.x.
I uploaded a sample file here https://ufile.io/y40ao
As you can see this is a GeoTIFF, so the missing tags in the output are 34264 (ModelTransformationTag), 34735 (GeoKeyDirectoryTag) and 42113 (GDAL_NODATA).

ImageMagick does not support proprietary TIFF tags.

All right, the post about a patch being on its way had me thinking otherwise.
Thanks for the information though.
