blendPre(byte[] pi,
byte[] pm)
Puts the
pi (the greyscale channel) into the R, G and B components of the returned int[]
after having multiplied them by the pm (the alpha channel); the alpha channel gets inserted into
the int[] as well. |
static int[] |
blendPre(byte[] r,
byte[] g,
byte[] b,
byte[] alpha)
Pre-multiplies alpha.
|
static byte[] |
merge(byte[] alpha,
byte[] outside)
Merges into alpha if outside is null, otherwise returns alpha as is.
