Hi Guys
I have a view that contains an ImageView. The ImageView is populated with a png resource, and fills the width and height of the image view.
Instead of this configuration, I would like to display the image zoomed in by an arbitrary percentage, and translated by an arbitrary coordinate. My question is, how can I configure an image view to display a sub-region of it's src bitmap, with arbitrary translation?
I would really appreciate your help.
Thanks
You can do this with matrix scaleType
1-Make a ImageView to have matrix scaleType, android:scaleType="matrix"
2-Create and manipulate a Matrix like this,
Matrix matrix = new Matrix();matrix.postTranslate(-10, -10);matrix.postScale(2, 2);3-set this matrix to ImageView, imageView.setImageMatrix(matrix)
