Hi everyone,

from version 7.2.0.0 the AddProfile method, using a device link icc profile, is very slow.
My simple code is:

Code: Select all

using(MagickImage mi = new MagickImage(@"E:\IN.tif"))
{
    mi.AddProfile(new ColorProfile(@"E:\DeviceLink.icc"));
    mi.Write(@"E:\OUT.tif");
}

You can find the IN.tif (CMYK 600 dpi LZW TIFF) file here:

and the device link (CMYK to CMYK) here:
https://www.dropbox.com/s/50t726x0scxqj ... k.icc?dl=0

Until version 7.1.0.0 the AddProfile method using .NET 4 x64 took about 1 second.
From version 7.2.0.0 it takes about 8,3 seconds (I've already tried the latest version).

The difference is huge.

I also read the change log but I've not found anything related.

Am I doing something worng or should I modify something in my code to restore the previous performance?

Thank you very much

Denis

What changed between those versions is support for HDRI color profile management. Wondering if that slowed it down. Will need to investigate this.

Ok, thank you very much.

It does look like this slow down was causing by adding support for HDRI color profile management. Will need to think of a way to fix this. Will get back to you when I have more info.

I understand. Thank you for your update.

Hello Dirk,

have you found any solution to process color image conversion without HDRI color profile management?

Thank you and best regards,

Denis

Sorry for no getting back to this topic. This should be resolved in the latest release. Or are you using the HDRI build of Magick.NET?

Ok thank you very much.
Actually I'm not using the HDRI Version but I was waiting to this fix for upgrading to the latest version of the library in my projects.
