Color shift after transforming color space

[rgdcastro]

Hi there,

I am trying to convert a JPG image with USWebCoatedSWOP color profile to AdobeRGB1998.

However, there is a bit of a color shift when I try to use the following function,
_image.TransformColorSpace(ColorProfile.USWebCoatedSWOP, ColorProfile.AdobeRGB1998);

I have attached a screenshot of the images in Photoshop. You'll see that the black parts became somewhat grayish.

Original:

Converted:

I have tried doing the conversion on Adobe Photoshop and that doesn't seem to happen there.

Am I missing something?

Is your input image a CMYK image and can you share the image?
