Hi Philipp, as far as I know PixelWriter, WritableImage and ImageView fits better for handling raster images than Canvas.
TestFX uses PixelWriter.setArgb() to convert screenshots from Glass with Monocle to PNG files: https://github.com/TestFX/TestFX/blob/fd75122/subprojects/testfx-core/src/main/java/org/testfx/service/adapter/impl/GlassRobotAdapter.java#L230 --Benjamin On Wed, Apr 29, 2015 at 4:21 PM, Philipp Dörfler <phdoerf...@gmail.com> wrote: > Hello list, > > I got some very low level pixel data residing in memory with a pixel > format and want to get that into JavaFX.
