For certain reasons I had to install ImageMagick on Mac OX 10.5 (Leopard) from the source.
Up to my knowledge I managed to install necessary delegates for reading tiff files:
> display -list configure|grep DELEGATES
DELEGATES bzlib fftw freetype jpeg jng png tiff x11 xml zlib
However, I seem to get error messages on a specic tiff file (which seems to have multiple layers).
The error message
> display EBImage/inst/images/nuclei-old.tif
display: EBImage/inst/images/nuclei-old.tif: unknown field with tag 347 (0x15b) encountered. `TIFFReadDirectory' @ warning/tiff.c/TIFFWarnings/704.
display: compression not supported `EBImage/inst/images/nuclei-old.tif' @ error/tiff.c/ReadTIFFImage/995.
is too cryptic for me. Can anybody help me to guess which delegate or dependency I left uninstalled
A weird error message

Re: A weird error message
You can generally ignore such messages or disable them using -quiet

What it means is that the TIFF contains some unknown application dependant tags that IM does not know how to handle.
The TIFF file format has been hacked by just about every application that decided to use it. These applications save extra meta-data with the images in these 'unknown tags'. Scanners are particularly nasty in this respect as they save non-standard information about the scanner settings used in such tags. Generally you can ignore them.
