In this example, the Overlay image is simply a black shape. There is no anti-aliasing or
feathering around the edges, which appear jagged:
DVD subpicture colors are extremely limited, so each pixel in a subpicture is either a solid
color or transparent. If your Overlay images have anti-aliased edges, those pixels will
become either transparent or solid when the button is used in DVDit Pro HD. The jagged
edges are less noticeable on a TV screen than a computer monitor, due to the TV’s lower
picture quality.
Images in the Overlay layer can use up to four colors:
• Black: Red 0, Green 0, Blue 0
• White: Red 255, Green 255, Blue 255
• Red: Red 255, Green 0, Blue 0
• Blue: Red 0, Green 0, Blue 255
Transparent areas of the layer are treated as white.
In DVDit Pro HD, you map each color in the Overlay layer to a different set of selection
state colors:
