Android裁剪位图

Question

I need to programmatically crop specific area from bitmap, like blue area on this image

How I can do it?

Answer 1

It's just like below:

// x refers to width, y refers to height
//first find startx, starty, endx, endy
Bitmap blueArea = Bitmap.createBitmap(bitmap, startx, starty, endx, endy);
