Panning and specular and reflection effects for Android images

In the previous article on the introduction of the image rotation and scaling, this article continues to describe the operation of the picture

Panning the picture

Use the following code to shift the horizontal vertical direction of the diagram by 10 pixels

Matrix.settranslate (10, 10);

You can see that the picture is incomplete and you need to modify the code:

// Create a new bitmap Bitmap Alterbitmap = Bitmap.createbitmap (Bitmap1.getwidth () * 2,                * 2, Bitmap1.getconfig ());

No other code is changed

The mirror effect of the picture

The code is as follows:

Matrix.setscale ( -1, 10);

The effect of the implementation:

The reflection effect of the picture

The code is as follows:

// Reflection Effect Matrix.setscale (1,-1); Matrix.posttranslate (0, Bitmap1.getheight ());        

The effect of the implementation:

The complete code is as follows:
