Hello, I'm sure this has been asked many times before but I cannot find a definite answer. How do I need to configure libtiff (3.9.4) or libjpeg(8c) to allow for proper conversion from CMYK to RGB? I have a JPEG compressed TIFF file from Photoshop. All currention IM version I compile will have inver...

found it myself

I compile "--with-x"
This lead somehow to usage of an old libfreetype.
Recompiling "--without-x" cured it.

Cheers, Axel.

I have the same failures with IM 6.6.9-4 Q16 lt-wandtest: delegate library support not built-in `none' (Freetype) @ warning/annotate.c/RenderFreetype/1508. lt-wandtest: Postscript delegate failed `/tmp/magick-p378BWCw': @ error/ps.c/ReadPSImage/806. wand/wandtest.c main 532 Reading images... just wi...

Hello all, I experience a failure with 6.6.9-4 if I enable HDRI. Without HDRI all tests pass. From tests/validate-formats-on-disk.log: test 317: PCT/Undefined/PaletteMatte/8-bits... fail (with distortion 8.41707e+57). Could you please try to reproduce this or give detailed debugging instructions. Th...

Hello all, I observe some unwanted blurring when I convert an image from RGB JPEG to CMYK JPEG. This can be seen in screenshot taken from Photoshop, input upper left, output lower left: http://dl.dropbox.com/u/84530/IM/cmyk-jpeg-blurred.png If I leave out color management or if I convert from one RG...

same problem with Snow Leopard and Intel CPU

It seems that Preview works fine if it finds Photoshop tags. If I patch the IM produced CMYK JPEG with exiftool : cp logo-im-cmyk.jpg logo-im-patched.jpg exiftool -tagsfromfile logo-psd-cmyk.jpg -photoshop:all logo-im-patched.jpg Preview is displaying the result as expected. Could I add the Photosho...

Thanks for keeping the topic alive. Apple Preview seems to have a problem with CMYK JPEG. I tried again using different approaches like this: cd /tmp rm -f logo-rgb.jpg logo-sips-cmyk.jpg logo-im-cmyk.jpg logo-psd-cmyk.jpg convert logo: -profile rgb.icm logo-rgb.jpg sips -m cmyk.icc logo-rgb.jpg --o...

Out of curiosity I tried with an older IM 6.5.9-10.
The output there looks fine when viewed with Preview.app.

I contiue checking this later.

I can confirm this. Neither Apple's QuickView or Preview.app properly displays any CMYK JPEGs created with current ImageMagick versions. I just do convert logo: -profile rgb.icc -profile cmyk.icc -colorspace cmyk -strip logo.jpg The output "logo.jpg" is ok. when checked in Photoshop but no...

I checked again with 6.6.7-3. PNG conversions are back at normal speed.

Regard, Axel.

Wonderful.

Thanks for correcting this. PNG conversion are back to normal speed in my tests.


Thanks, Axel.

Hello all, I observe certain JPEG files with a clipping path which don't convert properly. Normally the following command: convert jpg:path-ok.jpg -alpha transparent -clip -alpha opaque -resize 300x300 png:path-ok-clipped.png does a great job. Input: http://dl.dropbox.com/u/84530/IM/path-ok.jpg Outp...

Just as a reminder and another viewpoint

convert logo: -resize 1000% tmp.tif

takes 2 seconds

convert logo: -resize 1000% tmp.png

takes 2 minutes with 6.6.7-2 on my machine.

The phenomenon disappeared with 6.6.7-2.
