The agent captures dynamic feature accesses and creates configuration files automatically. ByteBuffer bgraPixels convertToBgra(rawPixels) // convert your byte array into a ByteBuffer in bgra format.

Until recently, if you wanted to load a BufferedImage in JavaFX you were out of luck the only way to do it was to write out the BufferedImage to disk and then read it back in as a JavaFX Image. These dynamic feature usages must be configured beforehand using JSON files as described here. In this case, the feature being used, such as the name of the method called, is not known at image build time, so NIK cannot figure out exactly which method is called. Many applications make use of dynamic language features such as reflective or JNI access. H:ExcludeResources='.*'Īlternatively, resources can be configured using JSON files. There are two options to include and exclude resource identifiers, and you can use wildcards there: These resources must be made known to native-image so that it includes them in the resulting executable.
