android - How to make glow effect around a bitmap? -


the following code got far. however, there 2 issues:

  1. i want both inner , outer glow effects, similar photoshop's blending options. managed make outer glow, if set blurmaskfilter.blur.inner or other value, whole image blocked, instead of edges.

  2. despite set "ff" alpha value, glow color still dark.

    bitmap alpha = origin.extractalpha(); blurmaskfilter blurmaskfilter = new blurmaskfilter(5, blurmaskfilter.blur.outer);  paint paint = new paint(); paint.setmaskfilter(blurmaskfilter); paint.setcolor(0xffffffff);  canvas canvas = new canvas(origin); canvas.drawbitmap(alpha, 0, 0, paint);  return origin;

alt text

try one. 

private void setbackgroundglow(imageview imgview, int imageicon,int r,int g,int b) { // added margin initial image     int margin = 24;     int halfmargin = margin / 2;     // glow radius     int glowradius = 40;      // glow color     int glowcolor = color.rgb(r, g, b);      // original image use     bitmap src = bitmapfactory.decoderesource(getresources(),imageicon);      // extract alpha source image     bitmap alpha = src.extractalpha();      // output bitmap (with icon + glow)     bitmap bmp =  bitmap.createbitmap(src.getwidth() + margin, src.getheight() + margin, bitmap.config.argb_8888);      // canvas paint on image     canvas canvas = new canvas(bmp);      paint paint = new paint();     paint.setcolor(glowcolor);      // outer glow     paint.setmaskfilter(new blurmaskfilter(glowradius, blur.outer));//for inner glow set blur.inner     canvas.drawbitmap(alpha, halfmargin, halfmargin, paint);      // original icon     canvas.drawbitmap(src, halfmargin, halfmargin, null);      imgview.setimagebitmap(bmp);   }
