从 AWT 和 JAI 转换为 Android

Question

我在将 java 项目转换为 android 项目时遇到问题。是什么让 我混淆相当于 SampleModel、ColorModel、WritableRaster， 和 Android 的 TiledImage ？以下是截取的代码：

SampleModel sampleModel = RasterFactory.createBandedSampleModel(
               DataBuffer.TYPE_BYTE, 4 * numXTiles, 4* numYTiles, 1);
   ColorModel colorModel = PlanarImage.createColorModel(sampleModel);
   WritableRaster decWRaster = RasterFactory.createWritableRaster(
               sampleModel, null);
   for (int j = 0; j < numYTiles; j++) {
            for (int i = 0; i < numXTiles; i++) {
               int indexEnc = disEnc.readByte();
               if (indexEnc < 0) indexEnc = indexEnc + 128;
               System.out.print(indexEnc + " ");

               int[] codeWord = codeBook[indexEnc];
               decWRaster.setPixels(i * 4, j * 4, 4, 4, codeWord);
            }
         }
         TiledImage decTImage = new TiledImage(0, 0, 4 * numXTiles,
               4 * numYTiles, 0, 0, sampleModel, colorModel);
         decTImage.setData(decWRaster);
         JAI.create("FileStore", decTImage, decPath + "test4.bmp",
"BMP");

该代码用于创建一个以 int[] 作为输入的图像，并平铺 每个像素为 4x4 框，宽度为 numXTiles*4，高度为 numYTiles*4。

有人可以帮忙吗？非常感谢:)
