Hello,
I am trying to use the Jpeg2000SaveOptions in order to compress and save the Raster Image using the following method:

private byte[] Compress(byte[] imageData, int qualityFactor)
        {
            RasterImage image = LoadRasterImage(imageData);
            m_Codecs.Options.Jpeg2000.Save.CompressionControl = CodecsJpeg2000CompressionControl.QualityFactor;
            m_Codecs.Options.Jpeg2000.Save.CompressionRatio = qualityFactor;
           MemoryStream stream = new MemoryStream();
            m_Codecs.Save(image, stream, RasterImageFormat.J2k, 0);

            return stream.ToArray();
        }


No matter what qualityFactor I use, the image compression doesn't seem to be working. Am I doing something wrong out here? Any help would be highly appreciated.

Thank You
Anup

Anup,


You should not pass the QualityFactor value to the "CodecsJpegSaveOptions.CompressionRatio"
property, you should pass it to the "CodecsJpegSaveOptions.QualityFactor" property instead.
