Hi

A few weeks ago, I scanned a set of SEM images on a Mac OSX connected scanner and saved them as tif files. I transferred these files to my Debian laptop, and tried converting them to .png images using :

convert $1.tif $1.png

Now when I include these in my tex document and run pdflatex, it completely messes up my PDF bookmarks (if I replace these converted png images with some vanilla png images, everything is fine). I can still view and print the document, but the electronic form of the document is a mess.

If I try to view these tif files, with xv, it quits with segmentation fault. kuickview does show the images but with a slew of errors in the console log.

tiffinfo yields :

tiffinfo bst1.tif
bst1.tif: Warning, unknown field with tag 700 (0x2bc) ignored. bst1.tif: Warning, unknown field with tag 34665 (0x8769) ignored. TIFF Directory at offset 0x8
Subfile Type: (0 = 0x0)

Apparently these 700 and 34665 tags are causing some problem (there are some issues which I found on Google that these tags throw up in other contexts as well - see
http://sourceforge.net/mailarchive/forum.php?forum_id=5790&a mp;max_rows=25&style=nested&viewmonth=200403 ).

Is there some tool that I could use to get rid of these pesky tags that are probably (and feel free to suggest otherwise if something else is the cause) causing these headaches ?

Thanks.

PS : I understand now why pdflatex does not support tif natively any longer.
