224 Glossary
FXDeko User’s Guide
layer
A layer is one element of a FXDeko graphic. A layer is either a text
layer, a rectangle layer or an ellipse layer.
A graphic can have any number of layers. Layers are rendered from
front to back.
layer browser
The layer browser shows a thumbnail image of each layer in the
current graphic, and displays the layer’s name and order. Type the
first one or two letters of the layer name to jump to that layer’s
thumbnail. You can click a thumbnail to select a layer, or reorder
layers by dragging and dropping them within the browser.
layout
The layout is the arrangement of windows and toolbars on the
desktop. FXDeko provides several pre-configured layouts for
composing, editing and playing back graphics and macros.
leading
Leading refers to the spacing between rows of text. The higher the
leading amount, the more space there is between rows.
“Leading” rhymes with “wedding.”
linear key signal
A linear key signal varies from black to white, including
intermediate gray shades. This is in contrast (no pun intended) to a
hard key signal, which has areas of either black or white but no
gray.
A linear key signal is required for keyed graphics to look properly
anti-aliased over background video. Your switcher must be capable
of handling linear key.
list parameter
A list parameter, also known as a repeating parameter, specifies a
list of one or more values. Depending on the command, the values
on the list may or may not be of the same type.
A command can have no more than one list parameter, which is
usually the last parameter.
local variable
A local variable is used exclusively in the current macro, and is
deleted when the macro ends. By default, user-defined variables are
local variables.
One macro cannot reference a second macro’s local variables, even
if the second macro is a subroutine of the first.
look
A look controls everything about the way a text character looks—
colors, edges, shadows, etc. A look is made up of a list of details.
