● How VC1E creates an image plane

YGV639

Image Plane Constitution

The screen which VC1E displays consists of 341 hierarchical images, called a layer, one backdrop plane,

and a border plane with a single color.

Any one among sprite, two or more lines, and text can be selected in one layer. One sprite, one character

string, and lines (up to 510) can be displayed on one layer.

(1) Sprite

(2) Two or more lines

(3) character string

abc

The display priority order of layers is in order of a layer, a backdrop plane, and a border plane from the top.

When a layer or an external video image is not displayed, the border color which is set for the border plane is

displayed.

Also when sprites are overlaid and displayed, a lower image comes to appear by setting the surroundings

of sprites as a transparent color. Moreover, images can also be overlaid as translucent. This is called alpha

blending.
