> Few TeX systems support TIFF as an imagie format. Given that there are literally several hundred image and graphics format, most implementations support only a few and rely on conversion for the rest.
this is true. however, pdtex is one of the few that does, and re is obviously using it.

> Tiff files worked. Why was it taken out? Including Tiffs has proven a lot more reliable than including PDFs. Particularly including PDFs generated by propritary software.
there are many kinds of tiffs and keeping up with all its flavors is a pain; the problem is that a tiff file needs to be converted to something that pdf can handle (compression, sampling, etc); in the pdf reference manual you can find more details on that. What gets accepted by pdftex depends on to what extend the standards are obeyed. Both pdf and tiff are propritary standards (both adobe). Since tiff is just a container format the problem is in all those non standard taggs that can be in there. tiff was taken out when it ended up in a continuous update (apart from doubling the size of the pdftex binaries);
- The support for the inclusion of tif images has been removed as it was of
limited use (it worked only for gray-scale and rgb images) and produced wrong
results (all other images types where treated as rgb images).
Tif images can be converted on *nix on-the-fly to pngs with the help of
ImageMagick, epstopdf.sty or pdftex.def v0.4 or newer, and this rule:
\DeclareGraphicsRule{.tif}{png}{.png}{`convert #1 `basename #1 .tif`.png}

Je vraag is dus niet 'Kan ik figuren invoegen in LaTeX', een vraag die heel erg simpel is te beantwoorden. De vraag is 'Kan ik TIFF invoegen in LaTeX', dus ik pas de topictitel aan

Edit:
de link van j-w levert inderdaad wat meer op, ik keek te specifiek naar PDF output
http://groups.google.nl/g...t&hl=nl&lr=&start=20&sa=N is trouwenshandiger, zo vindt je bijvoorbeeld een verwijzing naar tiff2ps. Dat is "natuuriljk" een *Nix applicatie maar [google=tiff2ps.exe] geeft verwijzingen naar een Windows versie:

Met de hand omzetten naar ps / eps kan trouwens vast ook.
