alphaThreshold
Usage
-- Lingo syntax
memberObjRef.alphaThreshold
// JavaScript syntax
memberObjRef.alphaThreshold;
Description
Bitmap cast member property; governs how the bitmap’s alpha channel affects hit detection. This
property is a value from 0 to 255, that exactly matches alpha values in the alpha channel for a
32-bit bitmap image.
For a given
alphaThreshold setting, Director detects a mouse click if the pixel value of the alpha
map at that point is equal to or greater than the threshold. Setting the
alphaThreshold to 0
makes all pixels opaque to hit detection regardless of the contents of the alpha channel.
