The combined ARGB value consists of the alpha component in bits 24-31, the red component in bits 16-23, the green component in bits 8-15, and the blue component in bits 0-7 where bit 0 is the least significant bit.
// Creating a colour with an alpha component. // Note order of parameters is RGBA, not ARGB as they are internally. // Dark orange is #ff8c00 in HTML. Color almostTransparentDarkOrange = new Color( 0xff /* red */, 0x8c /* green */, 0x00 /* blue */, 0x1f /* alpha */ );
In the Masker Applet, I create an image, an email address painted on a transparent background, defined with alpha=0, then write the whole thing to a *.png image file on disk.
