Return Value
The active bits for the alpha channel. Possible values are 1 and 8. If the
value is 1 it means the 256 levels of the 8-bit alpha channels will be
transformed into two levels of value 255 or 0, using simple threshold.
The threshold value is 127, so all values gt; 127 will be set to 255 and
all values lt;= 127 will be set to 0. If the value is 8, all 256
levels of the 8-bit alpha channels will be compressed. This is the default value. This
option should be used on a 32-bit bitmap otherwise it has no effect.
