Example
These statements check the
coordinates of 40 and 60:
-- Lingo syntax
put(constrainV(1, 20)) -- 40
put(constrainV(1, 55)) -- 55
put(constrainV(1, 100)) -- 60
// JavaScript syntax
put(constrainV(1, 20)); // 40
put(constrainV(1, 55)); // 55
put(constrainV(1, 100)); // 60
This statement constrains a moveable slider (sprite 1) to the edges of a gauge (sprite 2) when the
mouse pointer moves past the edge of the gauge:
-- Lingo syntax
sprite(1).locV = _movie.constrainV(2, _mouse.mouseH)
// JavaScript syntax
sprite(1).locV = _movie.constrainV(2, _mouse.mouseH);

Usage

// JavaScript syntax

Description
Image method. Copies the contents of a rectangle in an existing image object into a new
image object.
When copying pixels from one area of a cast member to another area of the same member, it is
best to copy the pixels first into a duplicate image object before copying them back into the
original member. Copying directly from one area to another in the same image is not
recommended.
To simulate matte ink with
