Translating image data types between Lingo and ActionScript 17

convert()

Usage

-- Lingo syntax

convert(targetDataFormat, sourceDataRef)

sprite(whichSprite).convert(targetDataFormat, sourceDataRef)

// JavaScript syntax

convert(targetDataFormat, sourceDataRef);

sprite(whichSprite).covert(targetDataFormat, sourceDataRef);

Description

Top-level function or Flash sprite method. Translates image, rectangle, and list/array objects

between Lingo (Director) and ActionScript (Flash). Returns a reference to the converted

object. For example, in the following code,

x is a valid reference to an ActionScript Rectangle

value:

x = newObject("flash.geom.Rectangle")

In the following code, y is a a valid reference to a Lingo rect value:

y = convert(#rect, z)

The following table lists the equivalent Lingo and ActionScript objects:

Lingo data type ActionScript data type

image BitmapData

rect Rectangle

list Array

NOTE

The convert() method does not operate on points. To convert an ActionScript Point

object to a Lingo Point object, pass the ActionScript Point object to the Lingo

point()

function. To convert a Lingo

point variable to an ActionScript Point object, use the

newObject() function.

NOTE

These ActionScript data types are also called classes. They are documented in the

ActionScript classes section of the ActionScript 2.0 Language Reference in Flash Help.
