IllegalArgumentException: x + width must be <= bitmap.width() in android

问题

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);

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

 FATAL EXCEPTION: main

How can i solve this?

回答1:

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

回答2:

    Bitmap resultBitmap = Bitmap.createBitmap(sourceBitmap, 0, 0,
            sourceBitmap.getWidth() - 1, sourceBitmap.getHeight() - 1);

Like in lists, it starts from 0, so width must be bitmap width - 1.
