How to convert color between Lab and CMYK space in Automation Plug-ins?

[_chenym_]

Hi, all,

We are currently developing a photoshop automation Plug-in with Photoshop SDK, we need to convert colors between CMYK and Lab, although this functionality is documented in Color Picker Plug-in APIs, how to do it in Automation Plug-in?

I think you can do an acquiresuite in the automation plug-in. I don't have the headers on this machine to see what the suite names are. ColorServicesProc or something like that....

Developing a Photoshop automation plug-in that requires converting colors between CMYK and Lab color spaces involves using the Photoshop SDK (Software Development Kit). While you've noted that the Color Picker Plug-in APIs document the process for color conversion, the approach in an Automation Plug-in might not be straightforwardly documented.

I am not critizising the content of your post but are you aware that the thread is from 2006?

No problem, just don’t be disappointed if the original poster should not answer.

In automation plugin world you look for suites you can acquire. Looking at the public API folder *color*.* I see photoshopapi\photoshop\PIColorSpaceSuite.h that looks like functions similar to ColorServicesProc . Acquire that suite and hopefully it can convert for you.
