2006.05.15 21:40 "[Tiff] Problem converting jpeg to tiff", by Petter_Nyström
Hello list! This is just a wild shot out there, and maybe I'm firing in a complete wrong direction. Anyway, I'd be grateful for any word of help on this problem.
I am running Ubuntu Linux and its update system recently updated my libtiff libraries, to a current version of 3.7.3. I have now discovered that the ImageMagick command line tool convert, cannot convert jpeg to tiff anylonger. This used to work just fine, and I am assuming the update that I vaguely recall is the cause of the problem. I do unfortunately not know what version of libtiff I had before the update, though I suppose one could find out about that with some investigation.
When running the convert command line tool I get an error, like this.
> convert image.jpg image.tif
convert: tif_jpeg.c:1505: JPEGCleanup: Assertion `sp != 0' failed.
I asked the ImageMagick people about this, and got the response that they hadn't seen this problem before and that I should ask the libtiff people. I suppose that'd be you, otherwise I'm completely out of place.
Any help or advice on the matter would be much appreciated. I am not very knowledgeable about either tiff, libtiff or linux in general.
Thanks in advance,
