| Alpha Blending is a technique that allows you to use the Alpha channel of an object to make parts of the object transparent. This concept has been used in the Blend effect option in the Effects tab of an object’s Properties dialog. The Alpha channel uses a greyscale image to set different levels of transparency. Any part of the image that is solid black is 100% transparent and any part that is solid white is opaque (i.e. 0% transparent). A sliding scale of transparency is then applied to greys so that darker greys are more transparent that lighter greys. |
