@magick: yes, i agree that i can get good results with IM if i use other output then PDF.

But the problem is PDF output, becouse profiles striped (or not correct included)

testphoto with included ProPhoto RGB ICC i grabed from here:

Portraits looks "brown" / "mucky" if you browser has no colormanagement (e.g. Chrom)

result with Illustrator/Photoshop (simplest PDF ...

not a academical question. very practical from my point of view.

advantage of PDF is everyboday has acrobat reader installed for print the final images
with JPEG or TIF you have a lot of differend tools to open and print , even with standard system.
some does not correct use JPEG included sizes ...

try the "sample" operator.

The "-sample" resize operator is the fastest resize operator, especially in large scale image reduction.

also try "Resize During Image Read" with [2000x2000] direct after the filename

as far as i can see no profile included in your CMYK image.
for that your first -profile applies the (wrong!) srgb.icm to the image and then colorspace does some conversation ...

with no profile within input image try:
convert "cmyk-in.jpg" -profile cmyk.icc -profile srgb.icm "out-rgb.jpg"

if i save a PDF with Illustrator and have include an image with embedded icc profile Photoshop recognized this profile correct!
so it seams to be a IM issue?

good point!
as far as i tested with CS3 and CS5.5 it does NOT work.

so anybody has a "workaround" to put an icc profile to a PDF so Photoshop will use it?

Hi all,

i found some posts to this questions but not realy clear with this.

If i convert image with embedded icc profiles into PDF and i open this PDF with Photoshop no profile found/used.
Is there a way of getting a PDF with icc profile included so Photoshop can read/apply it correct?

IM 6.7.6-8 ...

thanks for explain anthony!
i give your c program a try and this runs much faster then the PHP-API so i will go forward with the c implementation.

thanks for your testing antony!
in you example you working with a new wand there you past alle parts. in this way i also got it working.

i was afraid about memory consuming becouse my application need to handle parallel big images.
so you have a copy of the original wand in memory and i hoped to ...

i did a test with Imagick and got the same result. As far as i understand Imagick is a differend wrapper for Imagmagick API so maybe the "error" is not a bug but my wrong thinking of how to use?


$resource = new Imagick('test.jpg');
$tmpres1= new Imagick();
$tmpres1 = $resource->clone();
$tmpres1 ...

this sound interesting for my application. if you need beta-tester just give me a beep :)

yes, i tryed all combinations (i think) and can not set the original image at the last one if i add a new image
:(

how can i check the memory consuming of a wand? MagickGetImageSize() returns after ...

i setup a new server for testing and used the latest ImageMagick-6.7.5-6 (i see there is a new ImageMagick-6.7.5-7 out right now) and MagickWandForPHP-1.0.8

i can work around with a new Wand and put the Images with MagickAddImage($resource2,$tmpres1); MagickAddImage($resource2,$resource ...

Hi Anthony,

thanks for your investigation.
the first MagickSetLastIterator($resource); has no effekt to the result
infront of the second MagickAddImage(); it works. i can set the position with MagickSetLastIterator($resource);

so i can get only "$resource - $tmpres1 - $tmpres2" or "$resource ...

Hi all,

i have a problem with the order of images put together with MagickAppendImages();


$resource = NewMagickWand();
MagickReadImage( $resource, 'test.jpg' );

$tmpres1 = CloneMagickWand($resource);
MagickFlopImage($tmpres1);
MagickAddImage($resource,$tmpres1);
DestroyMagickWand($tmpres1 ...
