Re: CMYK Images - bug? (Again)
You should have a look at a JPEG decoder like Sun's JIMI or Sun's JAI (Java Advanced Imaging API). You might find some usefull methods regarding the color model used by a JPEG image file. Wandering around JAI's JPEGImageDecoder, it extends ImageDecoderImpl. There's a method called decodeAsRenderedImage(), which returns a RenderedImage Then you can call getColorModel().getColorSpace().getName() or getType() on this RenderedImage and you should have an int representing the color model (CMYK, RGB, etc...) I havent tested it myself and I'm not an expert in JAI, but I guess it should work. Hope it helps !

Re: CMYK Images - bug? (Again)
Well opening them in Photoshop (if you have the possibility) and look at the Image->Mode There youll see which mode the picture is in: RGB, CMYK, Grayscale etc. Claes |-+---> | | fred redf | | | | | | | | | 26/02/2002 03:00| | | PM | | | Please respond | | | to fop-dev | | | | |-+---> >---| | | |To: [EMAIL PROTECTED] | |cc: (bcc: Claes Bergsten/NO/TJG) | |Subject: Re: CMYK Images - bug?

CMYK Images - bug? (Again)
Hi, I need some feedback on this. Is there a bug with external-graphics containing CMYK colors? I have tried several image formats now, and if I save them in RGB-mode they work fine but if I save the same image in CMYK-mode FOP gives following error: Error in XObject : Error while loading image file:/D:/CVS/BC/webApplication/images/tj2.jpg : class java.lang.Exception - Image error (I use Photoshop to save pictures) Cheers Claes Bergsten - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
