Convert tiff with jpg compression to jpg

[patricklarsson]

Hi! Im trying to convert a tif file that has been compressed to jpeg quality and saved with Photoshop.

My tif file can be found here: http://ut.patricklarsson.nu/example.tif

Convert -version

Code: Select all

Version: ImageMagick 6.8.7-0 2013-09-19 Q16 http://www.imagemagick.org

Delegates: bzlib jng jpeg lcms png png tiff xml zlib

I downloaded and installed ImageMagick following these instruction for OS X found here: http://www.imagemagick.org/script/binary-releases.php not the macport install.

This is the command im running:
convert /Users/patrick/Desktop/example.tif ~/Desktop/test.jpeg

And this is the error it returns:

Code: Select all

convert /Library/WebServer/Documents/ut/example.tif ~/Desktop/test.jpg
convert: Unknown field with tag 347 (0x15b) encountered. `TIFFReadDirectory' @ warning/tiff.c/TIFFWarnings/838.

convert: no images defined `/Users/patrick/Desktop/test.jpg' @ error/convert.c/ConvertImageCommand/3127.

If I save the tif file without any compression the convert works perfect, thanks in advance!

It works fine for me on IM 6.8.7.3 Q16 Mac OSX


convert example.tif tmp.jpg
convert: Incompatible type for "RichTIFFIPTC"; tag ignored. `TIFFFetchNormalTag' @ warning/tiff.c/TIFFWarnings/842.

All I get is a warning for an unknown tag which is ignored.

What version of libjpeg and libtiff are you using? Perhaps you need a more current version or some other associated delegate.


I installed all my delegates using MacPorts but installed IM from source.
