I try to convert with command line a Tiff file from a scan (gray and 600dpi). I tried many command and every time I had the result of a completely black image.

I tried to convert to jpg with many example to remove the transparency and i had the same result a black image.

What was your exact command line? What version of Imagemagick? What platform? Can you post a link to your tiff image? You can upload to any free hosting service such as dropbox (public folder) and put a link here.

Without seeing the image I can only guess. Maybe you've got a 10-bit or 12-bit image that gets converted to 16 bits without properly shifting.
There are various ways of fixing that but I don't have any handy. Maybe "-auto-level". It's been discussed recently on one of the forums here.

Version: ImageMagick 6.5.4-7 2014-02-10 Q16 OpenMP http://www.imagemagick.org
Platform Linux Red Hat CentOS release 6.4

The standard convert command: "convert source.tif destination.png"

I tried many other but I don't find any command is working, it's why I don't write-it.

Here the information from the identify of the tiff I want to convert

I get an error message when trying to view with Mac Preview that the file is damaged or a format not recognized.

When looking at the verbose info, IM says it is endian=msb but the tiff:endian is lsb. So that may be the issue.

2014-01-30 6.8.8-5 Glenn Randers-Pehrson <glennrp@image...>
Fixed new "-define png:swap-bytes" option (reference viewtopic.php?f=2&t=24818).

This works but require a relatively current IM version, though I get an error message or warning.

convert doc01521320140224135532_001.tif -define png:swap-bytes doc01521320140224135532_001.png

convert: Depreciated and troublesome old-style JPEG compression mode, please convert to new-style JPEG compression and notify vendor of writing software. `OJPEGSetupDecode' @ warning/tiff.c/TIFFWarnings/850.

On IM v6.8.8-7 on Windows 8.1, the conversion ... ... works fine for me, with the same warning message as fmw42.

That is a very old version. I suggest you upgrade.

Hello,

I am having the same issue with a TIFF file. I am able to display the bi-tonal image successfully. However, for the grayscale image, I encouter the following warning:

OJPEGSetupDecode: Warning, Depreciated and troublesome old-style JPEG compression mode, please convert to new-style JPEG compression and notify vendor of writing software.

And when I display the image in Qt, the image is completely black.

This is the output from the bi-tonal image that displays correctly:

Thanks for any help!

Which version of ImageMagick are you using? And what is your operating system.

Hi,

We are using imageMagick 5.0 and RHEL - Version 6.2.

Thanks1
Liz

ImageMagick 5.0 is more than 10 years old. How old are the libpng and the libtiff that you're using with it?

Above he says ImageMagick 6.5.4-7. So I suspect 5.0 is not correct, though still about 380 versions old.

Hi,

It looks like we are using 3.9.4 for the libtiff.

Thanks,
Liz
