11 | | JDK8 and JDK9 already ''use'' jpeg or turbojpeg system libraries in the background to do the heavy lifting, but there does not seem to be a proper way in those JDKs to delegate the scaling wish down to the JNI level. The imageio framework has {{{canSetSourceRenderSize()}}} to check if a plugin can handel a custom source render size, but this is currently (JDK7, JDK8, JDK9) not implemented for the JPEG decoder, see |
