问题描述

我拼命尝试从具有整数值的像素数组创建一个Image.不管使用WritableImage还是Canvas，总是说PixelFormat是BYTE_RGB或BYTE_BGRA_PRE，所以我不得不使用字节数组.

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.

是否可以将PixelFormat更改为<IntBuffer>，或者我是否忽略了另一个具有PixelFormat<IntBuffer>功能的组件?

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

推荐答案

您尚未在int[]中描述像素数据的结构，但可以按照以下步骤进行操作:

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);
