Convert (version 6.8.6-5) losing ICC

Postby sqlgodus » 2013-07-15T11:14:23-07:00

I am converting TIFFs to JPEGs. The TIFFs have an embedded color profile: Adobe RGB
I am using ImageMagick 6.8.6-5 and have tried both the 64bit and 32-bit versions for Windows.

Upon convert, the ICC is dropped from the resulting JPEG. I cannot sort out how to add it back in. I have tried the following:

convert test.tif test.jpg
convert test.tif -profile AdobeRGB1998.icc test.jpg
convert test.tif -profile AdobeRGB1998.icc -profile AdobeRGB1998.icc test.jpg

If I convert between TIFFs, the color profile is retained. If I convert between TIFF and PNG, the color profile is retained.

Is this a bug or am I just not running the command properly?

Thanks.
Andy

Thanks for the reference. At the bottom of that thread it says:

"Try 6.8.6-3. That should handle the ICC profile properly."

I am using 6.8.6-5. I will try down-grading to 6.8.6-3 to see if it was fixed and has now reappeared.

If it was fixed in 6.8.6.3 it should be still fixed in 6.8.6.5.

What are the exact conditions that it fails? Can you provide an example image and the exact command you used to make it fail. We can test that in 6.8.6.5.

v6.8.6-5 on Windows 7 doesn't seem to embed profiles in jpegs.

Code: Select all

I can confirm that also on Mac OSX

convert zelda3.jpg -profile /Users/fred/images/profiles/sRGB.icc zelda3p.jpg

result shows no Profiles associated with the output
