Create a rounded image for android Image Processing

The following is an example of Improving the rounded corner image made by our predecessors.

Public static Bitmap roundCorners (final Bitmap source, final float radius ){

Int width = source. getWidth ();

Int height = source. getHeight ();

Paint paint = new Paint ();

Paint. setAntiAlias (true );

Paint. setColor (android. graphics. Color. WHITE );

Bitmap clipped = Bitmap. createBitmap (width, height, Bitmap. Config. ARGB_8888 );

Canvas canvas = new Canvas (clipped );

Canvas. drawRoundRect (new RectF (0, 0, width, height), radius, radius,

Paint );

Paint. setXfermode (new porterduxfermode (android. graphics. PorterDuff. Mode. SRC_IN ));

Canvas. drawBitmap (source, 0, 0, paint );

Source. recycle ();

Return clipped;

}

Example:

/**

* Round the corners of a {@ link Bitmap}

*

* @ Param source

* @ Param radius

* @ Return rounded corner bitmap

*/

Public static Bitmap roundCorners (final Bitmap source, final float radius ){

Int width = source. getWidth ();

Int height = source. getHeight ();

Paint paint = new Paint ();

Paint. setAntiAlias (true );

Paint. setColor (WHITE );

Bitmap clipped = Bitmap. createBitmap (width, height, ARGB_8888 );

Canvas canvas = new Canvas (clipped );

Canvas. drawRoundRect (new RectF (0, 0, width, height), radius, radius,

Paint );

Paint. setXfermode (new porterduxfermode (DST_IN ));

Bitmap rounded = Bitmap. createBitmap (width, height, ARGB_8888 );

Canvas = new Canvas (rounded );

Canvas. drawBitmap (source, 0, 0, null );

Canvas. drawBitmap (clipped, 0, 0, paint );

Source. recycle ();

Clipped. recycle ();

Return rounded;

}
