The only way I could keep acrobat reader from changing the color space to
CMYK was to set the entire page containing our graphics to a transparency
group and then set the colorspace accordingly. See the VB code snippet
below.
Great! That worked.
Bruno/Paulo - can you guys please add this as a higher level API call
(say, on a PdfPage) for the future?
Thanks,
Leonard

This is explained in chapter 12 of iText in Action.
Some pseudocode (so that you can Google for the keywords):
PdfGState gs = new PdfGState();
gs.setBlendMode(choose state);
cb.setState(gs);

You need to set the COLORSPACE to DeviceRGB...
Thanks, but how can I achieve it? I tried

You need to put the colorspace into the blending space that you were
workign with before...
Look at the PDF Reference for details on page blending spaces...

Hi,
I have a problem with the Adobe Acrobat Reader and PDFs generated by iText.
The Acrobat Reader seems to mix or change colors, which are used in a
page if I use a image with an alpha channel.
I tracked down the problem to the method
