I haven't done much with bitmaps before, but am trying to do
a bunch now. I'm a little confused about the difference between the
draw() and merge() methods. Basically I want to have a square area
with a neutral grey boarder fade to a circular part in the middle
with various patterns. I'm using this for a displacement map and
want to have the neutral grey fade so that there is no hard
I'm making the neutral grey with a gradient fill set to pad
and it looks great.
I'm making the pattern that will show in the middle of the
circle with perlinNoise and it looks great.
Now I need to combine them. At first I thought merge would be
the best choice, since, well, since it is called MERGE. I did get
them to merge, but I really couldn't control it.
I then came across that the draw method can support blending
modes and that seemed to work. But then I tried it without a
blending mode and that even worked. So now I'm a bit confused
I know what the help files say, but what does that mean?
