Hi,

I am just evaluating LeadTools at the moment.
Looking at the different ways to specify compression on saving JPG2000 images.  I can use
codecs.Options.Jpeg2000.Save.CompressionControl = CodecsJpeg2000CompressionControl
.Lossless;
OR
codecs.Options.Jpeg2000.Save.CompressionControl = CodecsJpeg2000CompressionControl
.Ratio;
and use a corresponding float value for the ratio set with:
codecs.Options.Jpeg2000.Save.CompressionRatio = Convert.ToSingle(i);

But the option:
codecs.Options.Jpeg2000.Save.CompressionControl = CodecsJpeg2000CompressionControl
.QualityFactor;
does not have a corresponding value which I can set in the codecs.Options.Jpeg2000.Save options.

Why is that and what am I doing wrong?

Many thanks

John

John,

You can change the QualityFactor when saving JPEG2000 images by using the codecs.Options.Jpeg.Save.QualityFactor property.
For more information, please read the help topic "CodecsJpeg2000CompressionControl Enumeration" in the LEADTOOLS .Net documentation.

Thanks,
