Android:如何将位图数组转换为 Int 数组？

Question

我正在剪切一些 int 数组的图像...

int[] imagenes_originales = new int[] {
    R.drawable.image1,
    R.drawable.image2,
    R.drawable.image3,
    R.drawable.image4
}

int[] new_images;

for (a = 0; a <= 3; a++) {
    Bitmap bitmap = BitmapFactory.decodeResource(getResources(), imagenes_originales[a]);

    int x = bitmap.getWidth(), y = bitmap.getHeight();
    int escalax = getWindowManager().getDefaultDisplay().getWidth();

    Bitmap recorte = Bitmap.createBitmap(bitmap, 0, y / 2, escalax, 100);
}

如何转换 new_images[] 变量中的位图图像？

Answer 1

Bitmap bitmap = BitmapFactory.decodeResource(getResources(), imagenes_originales[a]);
int x = bitmap.getWidth();
int y = bitmap.getHeight();
int[] intArray = new int[x * y];
bitmap.getPixels(intArray, 0, x, 0, 0, x, y);

您的位图到 int 数组现在位于 intArray/
