[daisy] Images with color model CMYK

[Andreas Deininger]

Hi,

I just created a new document of type 'Image' and uploaded a jpeg-file
(3.0 MB) of color model CMYK. If I navigate to the document and click
on "download", I get the error message:

The image "http://mydomain/mysite/11500/version/2/part/3/data/cmykimage.jpg?branch=main&language=de"
cannot be displayed, because it contains errors." (However, if I right
click and save the attachment to my hard disk, I can view it without
problems).
After converting the image to color mode RGB and replacing the CMYK
version with the RGB version, the problem is gone.

The repository log tells:

[ERROR  ] <2006-07-10 11:18:57,124>

Is that a known issue or is that related to my installation/settings?
(I have JAI 1.1.3 installed with my JDK).
