> This PR is an improved version of #1093. > > JavaFX can load BMP, GIF, PNG, and JPEG images with its built-in image > loaders. It has been a long-standing request to support more image formats, > most notably (but not limited to) SVG. However, adding more built-in image > loaders is a significant effort not only in creating the functionality, but > also in maintaining the additional dependencies. > > This will probably not happen any time soon, so we are left with three > alternatives: > 1. Accept the fact that JavaFX will never be able to load additional image > formats. > 2. Create a public image loader API, and hope that developers in the JavaFX > ecosystem will create image loader plugins. > 3. Leverage the existing Java Image I/O API. > > From these options, I think we should simply support existing Java APIs; both > because it is the shortest and most realistic path forward, but also because > I don't think it is sensible to bifurcate pluggable image loading in the Java > ecosystem. > > Of course, Java Image I/O is a part of the `java.desktop` module, which as of > now, all JavaFX applications require. However, it has been noted in the > previous PR that we shouldn't lock JavaFX into the `java.desktop` dependency > even further. > > I've improved this PR to not permanently require the `java.desktop` > dependency: if the module is present, then JavaFX will use Image I/O for > image formats that it can't load with the built-in loaders; if the module is > not present, only the built-in loaders are available. > > I have prepared a small sample application that showcases how the feature can > be used to load SVG images in a JavaFX application: > https://github.com/mstr2/jfx-imageio-sample
