问题描述
我特林从网上下载图像,将其转换为ninepatch格式,我该如何选择拉伸像素超出范围为这个线程。
I'm tring to download an image from the net, and to convert it to ninepatch format, how I select the stretchable pixels is out of scope for this thread.
我试图使用但我无法得到它的工作。
I'm trying to use gist solution but I couldn't get it to work.
这是源$ C $ C:
This is the source code:
NinePatchDrawable np = createNinePathWithCapInsets(res, bitmap, top,left, bitmap.getWidth() - right, bitmap.getHeight() - bottom, null);
和得到的结果位图:
Bitmap outputBitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(outputBitmap);
//np.setBounds(0, 0, width, height);
np.draw(canvas);
canvas.drawBitmap(outputBitmap, width, height, new Paint());
返回的位图不包含源位图,看起来就像4分割(SEG RECT')
The returned bitmap doesn't contain the source bitmap and looks just like 4 segmentations(rect seg').
我能找到的任何其他才达到这一目标,甚至没有使用OpenGL
I could find any other to achive that goal, even not using OpenGL
所得图像是:
推荐答案
试试这个:
public static byte[] getChunk(int xs, int xe, int ys, int ye) {
ByteBuffer b = ByteBuffer.allocate(84).order(ByteOrder.nativeOrder());
b.put((byte) 1); // wasDeserialized
b.put((byte) 2); // numXDivs
b.put((byte) 2); // numYDivs
b.put((byte) 9); // numColors
b.putInt(0); // UNKNOWN
b.putInt(0); // UNKNOWN
b.putInt(0); // paddingLeft
b.putInt(0); // paddingRight
b.putInt(0); // paddingTop
b.putInt(0); // paddingBottom
b.putInt(0); // UNKNOWN
b.putInt(xs); // segX start
b.putInt(xe); // segX end
b.putInt(ys); // segY start
b.putInt(ye); // segY end
for (int i = 0; i < 9; i++) {
b.putInt(1); // NO_COLOR
}
return b.array();
}
您可以在NinePatchDrawable构造函数中使用它(位图,字节[],矩形,字符串)
you can use it in NinePatchDrawable constructor (Bitmap, byte[], Rect, String)
