another color can be selected by clicking Custom Color. A color selection dialog

will open in which the desired color can be selected. The color contained in the

Custom Color well is the actual color used for the ﬁlter.

13.32 Color to Alpha

Overview

The Color to Alpha ﬁlter replaces selected color information with alpha. The ﬁlter

will attempt to preserve antialiasing information by utilizing a partially intelligent routine

that replaces weak color information with weak alpha information. In this way, areas that

contain an element of the selected color will maintain a blended appearance with their

surrounding pixels. Color to Alpha Options
