Creating a Javafx image from a int array

问题:

I am desperately trying to create an Image from a pixel-array with integer values. Regardless of using the WritableImage or the Canvas, it is always said that the PixelFormat is BYTE_RGB or BYTE_BGRA_PRE, so that I am forced to use a byte-array.

Is there any way to change the PixelFormat to <IntBuffer> or did I overlook another component that is capable of having a PixelFormat<IntBuffer>?

回答1:

You haven't described the structure of the pixel data in your int[], but you can do something along the lines of

int[] pixels = ... ;
WritableImage img = new WritableImage(width, height);
PixelWriter pw = img.getPixelWriter();
pw.setPixels(0, 0, width, height, PixelFormat.getIntArgbInstance(), pixels, 0, width);
