Set icc profile on image

[vnkapoor]

I want to add sRGB icc profile on my image if interpretation is CMYK. I tried below code but didn't got any solution. I saw icc_transform, icc_import and icc_export method but not exactly get the idea which is for add icc the profile.

$iccProfilePath = 'sRGB2014.icc';
$image = Vips\Image::newFromFile($arg[1], ["access" => "sequential"]);
if ($image->interpretation == "cmyk") {
    $image = $image->icc_import(["embedded" => true, "input_profile" => $iccProfilePath]);
}
$image->writeToFile($arg[2]);

Hello @vnkapoor,

You need to give a lot more information: input images, the command you ran, expected output, any error messages, actual output.

@jcupitt I am not getting error, here i add my input and output image, hope it will be helpful to you.
Input Image -

Output image -

Command i am using for get image icc-data
vipsheader -a abc.jpg

Ah, you want to transform CMYK images to sRGB, is that right? Use:

vips icc_transform park.jpg x.jpg srgb

At the command-line to make:

In PHP it would be:

$image = Vips\Image::newFromFile("park.jpg", ["access" => "sequential"]);
$image = $image->icc_transform("srgb");
$image->writeToFile("x.jpg");

icc_transform moves an image between two device spaces, so in this case from CMYK to sRGB. Your input image has a profile, so you don't need to supply a CMYK input profile. libvips has a built-in srgb profile it'll pick automatically if you ask for srgb output.

@jcupitt I tried your above code it works. But i applied SRGB icc profile using imagick and vips but both image have some difference, here i added both images. For imagick i am using sRGB2014.icc profile.

Add icc profile using Imagick

Add icc profile using VIPS

I would try setting the rendering intent to perceptual, or using your own srgb profile.

@jcupitt How can i add my icc profile instead of vips SRGB. Is that any method for that.
For ex - If i want to add CoatedFOGRA27.icc on my image, how can i achieve that?

[jcupitt]

But that's a CMYK profile. You can't swap an RGB profile for a CMYK one.

Like I said, try perceptual rendering intent:

vips icc_transform park.jpg x.jpg srgb --intent perceptual

To make:

(default on the left, perceptual on the right)
