How to cut round:

Public Bitmap Toroundbitmap (Bitmap Bitmap) {int width = bitmap.getwidth (); int height = bitmap.getheight (); float roundpx;f Loat left, top, right, bottom, Dst_left, Dst_top, Dst_right, dst_bottom;if (width <= height) {roundpx = Width/2;left = 0;top = 0;right = Width;bottom = Width;height = Width;dst_left = 0;dst_top = 0;dst_right = Width;dst_bottom = width;} else {roundpx = height/2;float clip = (width-height)/2;left = Clip;right = Width-clip;top = 0;bottom = Height;widt H = height;dst_left = 0;dst_top = 0;dst_right = Height;dst_bottom = height;} Bitmap output = bitmap.createbitmap (width, height, config.argb_8888); Canvas canvas = new canvas (output), final paint paint = new paint (), final rect src = new rect ((int) left, (int) top, (int)  Right, (int) bottom); final rect dst = new rect ((int) dst_left, (int) dst_top, (int) dst_right, (int) dst_bottom); final RECTF RECTF = new RECTF (DST);p Aint.setantialias (TRUE);//Set Brush non-aliased canvas.drawargb (0, 0, 0, 0); Fill the entire canvas//below there are two ways to draw a circle, drawrounrectand Drawcirclecanvas.drawroundrect (RECTF, ROUNDPX, ROUNDPX, paint);//Draw rounded rectangles, the first parameter is a graphic display area, the second parameter and the third parameter are the horizontal fillet radius and the vertical fillet radius, respectively.
