Tiff does not use a delegate program, just coder that uses a library.
Delegates are external programs to convert from one format to another,
whether IM itself understands the format or not.
If TIFF appears on the list
convert -list format
then the coder was compiled into IM.
In my case I see
EPT EPT rw- Encapsulated PostScript with TIFF preview
EPT2 EPT rw- Encapsulated PostScript Level II with TIFF preview
EPT3 EPT rw+ Encapsulated PostScript Level III with TIFF preview
FAX* FAX rw+ Group 3 FAX
See TIFF format. Note that FAX machines use non-square pixels which
are 1.5 times wider than they are tall but computer displays use
square pixels. FAX images may appear to be narrow unless they are
explicitly resized using a resize specification of "150x100%".
PTIF* TIFF rw- Pyramid encoded TIFF
TIFF* TIFF rw+ Tagged Image File Format (LIBTIFF, Version 3.8.2)
TIFF64* TIFF --- Tagged Image File Format (64-bit) (LIBTIFF, Version 3
(DO NOT MAIL THE WHOLE LIST! - it is too long)
The coder is only loaded as it is needed, which ensures IM can be
installed without requiring every coder dependancy to be present.
Under my linux the coders are the .so file in
/usr/lib/ImageMagick-6.3.5/modules-Q16/coders/tiff.so
An ldd on this coder
ldd /usr/lib/ImageMagick-6.3.5/modules-Q16/coders/tiff.so
shows the line...
libtiff.so.3 => /usr/lib/libtiff.so.3 (0x00110000)
So it finds everything it needs to decode or generate the TIFF file
format.
Mind you I compile IM myself for my system so only coders that can work
on my system were generated. For binary installed IM that may not be
the case, and is why this system is used.
