It's entirely possible that you are changing it yourself.
The colormodel that the RasterImage returns may be affecting your output.
Try using iText's default Image.getInstance("imagePath");
constructor to test if this is the case.
Let me know

Subject: RE: [iText-questions] howto stop grayscale jpg lightening
automatically on output to pd f?
could i be changing the bytes myself without realizing it?
i use blow to get a RenderedImage from a SeekableStream created from the
JPEG :
private RenderedImage createRenderedImageFromJPEGStream(SeekableStream
inputStream)
throws IOException {
ImageDecoder decoder =
ImageCodec.createImageDecoder(
"jpeg",
inputStream,
((ImageDecodeParam) new JPEGDecodeParam()));
RenderedImage jpegImage = decoder.decodeAsRenderedImage(0);
return jpegImage;
}
after that i create an Itext Image from the the RenderedImage:
Raster ra = ri.getData();
BufferedImage bi =
new BufferedImage(
ri.getColorModel(),
Raster.createWritableRaster(
ri.getSampleModel(),
ra.getDataBuffer(),
null),
false,
new Hashtable());
Image img = Image.getInstance(bi, null, true);
THIS SHOULD NOT BE ALTERING THE BYTES RIGHT?

If I understand correctly, iText just dumps the jpeg data into the PDF file.
It does'nt adjust the jpeg, Acrobat must be doing that.
Try creating a java image and passing the bytes to iText instead and see if
that works.
Hope this helps

i have a grayscale jpg image that appears in all image viewers i have with a
dark gray background. when i output the image to pdf it appears as if itext
is automatically adjusting the colors on the page so that this dark gray is
white and other darker spots on the image are lightened by the same
amount...is there a way to turn this off??
