Loosing sharpness when applying ICC source profile

Post by bzv42 »

Hi,

I'm trying to convert images using color profiles.
When applying a source profile (as recommended in http://www.imagemagick.org/Usage/formats/#color_profile) the image dramatically looses sharpness. I used this command:

Code: Select all

convert -verbose source-rgb.jpg +profile icm -profile sRGB.icc -profile ISONewspaper26v4.icc dest-cmyk.jpg
When only applying the destination profile the result is ok:

Code: Select all

convert -verbose source-rgb.jpg +profile icm -profile ISONewspaper26v4.icc dest-cmyk.jpg
I tested this with
ImageMagick 6.1.9 01/23/05 Q16 and
ImageMagick 6.3.9 02/27/08 Q16 on
Windows 2000 and Windows XP.

Is this a bug or am I missing something?

Guido
