What steps will reproduce the problem?
1. Use Thumbnailator with a TIFF image.
What is the expected output? What do you see instead?
javax.imageio.IIOException: I/O error writing TIFF file!

What version of the product are you using? On what operating system? Which
version of Java (Sun/Oracle? OpenJDK?) ?
v0.4.5 on Java 1.7.0_10 with
jai-imageio-core-standalone-1.2-pre-dr-b04-2013-04-23.

Sorry for the late reply.
Thumbnailator by itself will not support TIFF images.
However, as you indicated, using external "plug-ins" to Image I/O (in this
case, JAI), it is possible to use formats which are not supported
out-of-the-box from the regular Java runtime.
In this case, looking at the stacktrace, the error appears to be caused by
trying to use RLE compression with an image that is not monochrome.
It is outside the scope of the Thumbnailator project to provide support for
using the `ImageReader`s and `ImageWriter`s that perform the actual
decompression/compression of the images themselves.
From the information provided in this issue, I was able to find the Javadoc for
the TIFF writer in question:
http://stain.github.io/jai-imageio-core/javadoc
In this particular issue, it appears that the compression type ("RLE") is not
suitable for the current image.
Therefore, to resolve this particular case, the `outputCompressionType` should
be specified to something other than RLE, and something that works with the
current image.
An example of using `outputCompressionType` would be like:
Thumbnails.of("path/to/image")
.size(100, 100)
.outputFormat("TIFF")
.outputFormatType(compressionTypeThatWorks)
.toFile("path/to/tiff");
-----------
I will consider this to be a case of insufficient documentation about how
decompression/compression is handled in Thumbnailator. (i.e. Thumbnailator is
just a wrapper around the Image I/O API.)
This issue will be merged with Issue 32, which is a similar issue regarding
supported formats.
