Hi Serge,

This is normal because JPEG files do not support images with palettes. This was like that in version 1 too. JPEG was designed for photographic like images.

To work around this, if the ImageFormat is not ifGray256 or ifTrueColor you need to use the TImageFormatTransform first to convert it. then you will be able to save as JPEG.

Best regard,
