Hi,
The following is giving me a serious headache.
Bitmap mTestMap = Bitmap.createBitmap(20, 20, Config.ALPHA_8);
mTestMap.setPixel(10,10, Color.WHITE);
Log.d("Test", "HasAlpha=" + mTestMap.hasAlpha() + ", IsMutable=" +
mTestMap.isMutable() +
", PixelColor=" + mTestMap.getPixel(10,10));
The output is:
08-11 10:56:23.490: DEBUG/Test(11211): HasAlpha=true, IsMutable=true,
PixelColor=0
The question is, why does getPixel return 0? And if it was meant to
return 0, what is the correct way to retrieve pixel color information
(or alpha channel information) from an ALPHA_8 bitmap? I am trying to
use this kind of bitmap for hit-testing in a game. RGB_565 works fine,
but I am trying to reduce the memory.
