When I add a comment to the image meta data, the conversion produces an error message, and in the destination file, the comment is not present.
The command I'm running is something like this
convert.exe C:\image.tiff -resize 700x380^ c:\image.jpg
...and the warning I get is: "convert.exe: Unknown field with tag 59932 (0xea1c) encountered. 'TIFFReadDirectory' @ warning/tiff.c/TIFFWarnings/905
The image I'm trying to convert is here: https://dl.dropboxusercontent.com/u/437 ... K-1066.tif
TIFF to JPG, image comment lost

Re: TIFF to JPG, image comment lost
These are warnings (not errors) that the TIFF file has some meta tag that IM does not understand. If you want to avoid these messages add -quiet just after convert. Your output image should be created even if you have these messages.
Re: TIFF to JPG, image comment lost
I'd really like to get the meta data across the conversion because it contains the description of the image. As far as I can see, the meta tag that's not understood is an EXIF XP Comment, see http://regex.info/exif.cgi?dummy=on&img ... K-1066.tif
Cheers

Re: TIFF to JPG, image comment lost
I am not a windows user. But that tag is not a standard EXIF comment, but is a windows xp specific comment, as far as I can tell. I do not think IM knows about that comment field. I do not see it in the IM verbose information. Is it there in the following?
This is the EXIFTOOL data that I extracted. Is it here?
If not in either, then one of the IM developers would have to look into this further to see about adding it.

Re: TIFF to JPG, image comment lost
The tag we're talking about is 40092 (XPComment), not 59932 (PADDING_DATA). As far as I can tell, 40092 is not supported by IM. It does appear in the EXIFTOOL output above.
Support for the tags 40091 through 40095 (and maybe some of 18246 through 18249) might be a nice feature, given that they are created by such popular software as Microsoft Windows (the "properties" or "details pane" in Windows Explorer).
