Android 如何在不使用遮罩的情况下创建拼图?_Android_Image Processing_Bitmap - Fatal编程技术网

Android 如何在不使用遮罩的情况下创建拼图?

Android 如何在不使用遮罩的情况下创建拼图?,android,image-processing,bitmap,Android,Image Processing,Bitmap,我正在尝试创建一个拼图游戏,我想知道不使用面具创建拼图块的替代方法。目前,我有一个完整的图像拼图块,把图像分成四块(假设拼图是2x2),然后存储和应用一个面具到每一块。它看起来像下图 // create standard puzzle pieces arryPieceEndPos = new int[mCols][mRows]; arryPieceImg = new Bitmap[mCols * mRows]; arryIsPieceLocked = new bo

我正在尝试创建一个拼图游戏,我想知道不使用面具创建拼图块的替代方法。目前,我有一个完整的图像拼图块,把图像分成四块(假设拼图是2x2),然后存储和应用一个面具到每一块。它看起来像下图

    // create standard puzzle pieces
    arryPieceEndPos = new int[mCols][mRows];
    arryPieceImg = new Bitmap[mCols * mRows];
    arryIsPieceLocked = new boolean[mCols * mRows];

    int pos = 0;
    for (int c = 0; c < mCols; c++) {
        for (int r = 0; r < mRows; r++) {
            arryPieceImg[pos] = Bitmap.createBitmap(mBitmap,
            c * mPieceWidth, r * mPieceHeight,
            mPieceWidth, mPieceHeight);

            arryIsPieceLocked[pos] = false;
            arryPieceEndPos[c][r] = pos;
            pos++;
        }
    }

我看到了这篇文章>,用于将各个部分连接在一起,但是,这并没有涉及到在没有遮罩的情况下以编程方式生成各个部分。有人能提供如何实现这一点的代码示例吗?我唯一的线索是我应该使用Path,但是,我仍然不知道如何使用。提前谢谢

拼图是一个非常复杂的视图,但我可以帮助您了解如何使用路径。以下是开发人员网站的链接:

查看此链接。我做了一件小事让你开始。你需要弄清楚的一件事是如何在路径上切出一个小圆圈,我不知道。我认为你必须研究裁剪,使你的路径沿着一个圆(你也可以在工件外创建一个圆,我只是以前没有做过裁剪)

我希望这足以开始这项工作


祝你好运

谢谢你的回答。哇,要得到一个完整的拼图块形状并让它看起来很好是非常复杂的。我现在的问题是从整个图像中创建片段,而不仅仅是图像的一部分,因为我需要能够移动这些片段等等。一般来说,对于android来说,使用掩码是更好的选择吗?你可以使用它来获取位图的一部分。我不知道什么更好,但使用面膜接缝要容易得多。如果您在使用路径等方面有很多问题,那么如果它与mask配合良好,可能就不值得这么麻烦了
private Bitmap maskMethod(Bitmap bmpOriginal, Bitmap bmpMask) {

    // adjust mask bitmap if size is not the size of the puzzle piece
    if (bmpMask.getHeight() != mPieceHeight ||
        bmpMask.getWidth() != mPieceWidth) {
        Log.e("TEST", "Resize Error :: H (mask): " + bmpMask.getHeight() + " // W (mask): " +
            bmpMask.getWidth());
        Log.d("TEST", "Resize Error :: H (norm): " + mPieceHeight + " // W (norm): " +
            mPieceWidth);

    }

    Canvas canvas = new Canvas();
    Bitmap combine = Bitmap.createBitmap(bmpOriginal.getWidth(), bmpOriginal.getHeight(), Bitmap.Config.ARGB_8888);
    canvas.setBitmap(combine);
    Paint paint = new Paint();
    paint.setFilterBitmap(false);

    canvas.drawBitmap(bmpOriginal, 0, 0, paint);
    paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.DST_IN));
    canvas.drawBitmap(bmpMask, 0, 0, paint);
    paint.setXfermode(null);

    return combine;
}
private Bitmap getPuzzleBitmap(Bitmap bitmap)
{
    Bitmap output = Bitmap.createBitmap(bitmap.getWidth(), bitmap.getHeight(), Bitmap.Config.ARGB_8888);
    Canvas canvas = new Canvas(output);

    final int color = 0xff424242;
    final Paint paint = new Paint();
    final Rect rect = new Rect(0, 0, bitmap.getWidth(), bitmap.getHeight());

    calculatePuzzlePath(bitmap.getWidth(), bitmap.getHeight());

    paint.setAntiAlias(true);
    canvas.drawARGB(0, 0, 0, 0);
    paint.setColor(color);
    canvas.drawPath(puzzlePath, paint);

    paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
    canvas.drawBitmap(bitmap, rect, rect, paint);

    return output;
}
