在Android中提取位图的顶部

Question

是否有一种简单的方法可以提取位图的顶部（如附件图像）并仅获取位图的底部？

Answer 1

It is quite easy actually. You have to use the method;

Bitmap dest=Bitmap.createBitmap(Bitmap source, int x, int y, int width, int height);

Here x and y are coordinates of starting points. In your case you want to set x to 0, y to something, width to the real width and height to a shorter one. Beware that the width and height you enter cannot be larger than the original bitmap's dimensions.
