CMYK Color Images with PDF Renderer

[Venkat Reddy]

Hi,

Can anyone know the classes and methods deals with the CMYK colored 
Images for PDF Renderer?

I want to know, where exactly the conversion taking palce between RGB 
and CMYK color spaces.
I have already worked with AFP and PS renderers for CMYK colored images, 
these renderers will use ImageEncodingHelper (XMLGraphicsCommons class) 
to render the respective
document with colored images. I thought the same class 
(ImageEncodingHelper) is not being used for PDF Renderer.

Can someone give me an idea? where this coversion is taking place?

Thanks,
Venkat.
