TIFF is a troublesome format, in that there are extremely many flavors.
Perhaps these libraries fail on the particular flavor you wish to use them
with, because, I guess they should work on some other flavors at least.

It may be helpfull if you investigate what TIFF it is you want to handle. To
this end, you can download my free TIFF Tag Viewer application. Here's the
official URL. Next is an URL of the installer of the very newest version,
that is not linked yet from my website since it's too hot and new and does
need some testing first. Please use this last URL only if you're interested
in giving feedback about this experimental new version

You can use this app to investigate your TIFF's tag set. Next, you can also
dump that tag set on the clipboard, with this app, and paste it into a
followup question in your mailclient, if you think that the problem is
caused by this particular flavor of TIFF and want to ask about that.

As to a 'TIFF in Delphi' solution... There will be one from my website,
soon, but I guess that's not very helpfull at this moment. Sorry.

Now we know the TIFF... Sure is a nice little app that dumped these tags for
you, isn't it? ;-)

The TIFF file is a typical fax file, like I've seen many before. It's black
and white, G3 compressed, properly divided in strips. The tricky part about
files like these is
1) often times, they are produced by fax solutions that directly dump the
error-prone fax data in the TIFF file without any form of error-correction.
Often leads to problems with picky decoders
2) the X and Y resolution of files like these is different. Many imaging
solutions don't support that, even if this type of file is quite common.

But, I guess the above doesn't quite solve your problem yet. What exactly is
the problem when decoding these files with ImageMagic or GraphicsEx? Do they
just crash unexpectedly, in which case 1) is probably to blame? Or do they
decode the fine file, but display it sortoff stretched, in which case 2) is
probably the reason? Or is it a product setup problem, or another problem
still?

If the problem is in the realm of unexpected error or crash or the like,
sent a copy of a typical file to me at XXXX@XXXXX.COM , and I'll
try and check whether bogus G3 data may be the cause.

What exactly do you need to do with these files?
