抛出：IllegalArgumentException：X +宽度必须＆LT; = bitmap.width（）在android系统 [英] IllegalArgumentException: x + width must be <= bitmap.width() in android

问题描述

我想用保证金（10,50,10,50）分别裁剪图像（左，上，右，下）的ImageView的的。这里是我的code

I want to crop an image with in a margin (10,50,10,50),(left,top,right,bottom) respectively of an imageview. Here is my code

Bitmap bitmap = Bitmap.createBitmap(imgView.getWidth(),imgView.getHeight(), Bitmap.Config.ARGB_8888);

Bitmap result = Bitmap.createBitmap(bitmap, (imgView.getLeft() + 10),
                imgView.getTop() + 50,imgView.getRight() - 10,imgView.getBottom() - 50);
bitmap.recycle();
Canvas canvas = new Canvas(result);
imgView.draw(canvas);

也就是说，如果我的ImageView的是维200X300.then我想在指定区域中唯一的。当我试图做到这一点用得到位图图像它显示误差

ie, if my imageview is of dimension 200X300.then i want to get the bitmap image with in the specified area only .When I am trying to do this It shows error

我怎样才能解决呢？

How can i solve this?

感谢

推荐答案

尝试这一点，看看它是否工作：

try this and see if it works:

// using this method createBitmap(source, x, y, width, height)
Bitmap result = Bitmap.createBitmap(bitmap, 10,
            50, imgView.getWidth() - 20, imgView.getHeight() - 100);

getLeft 和其他用于获取在其父视图的位置。位图的不是尺寸。

getLeft and others is used to get the position of the view in its parent. Not the dimension of the bitmap.
