About ActionScript image effects 15

The following example takes a Lingo image, converts it to an ActionScript BitmapData

object, applies an ActionScript blur effect to it, and renders it in Director as a 3D texture:

-- Get a Lingo image.

tImage = member("SomeImage").image.duplicate()

-- Create an ActionScript BlurFilter object. Note that the filter's

-- properties are default values. To specify non-default values,

-- pass additional parameters in the newObject() call.

tBlurFilter = newObject("flash.filters.BlurFilter")

-- Convert the image object to a BitmapData object.

tBitmapData = convert(#bitmapdata, tImage)

-- Apply the blur filter to the BitmapData object.

-- Trap the returned result value for error checking.

tResult = tBitmapData.applyFilter(tBitmapData, tBitmapData.Rectangle,

newObject("Point",0,0), tBlurFilter)

-- Use the returned result value to error check.

-- A value of zero indicates that no error occurred.

-- Negative values indicate that an error occurred.

if (tResult = 0) then

-- Convert the blurred BitmapData object back to a Lingo image object

tBlurryImg = convert(#image,tBitmapData)

-- Use the image object to create a new texture and apply it to a model in

the scene

tTexture = member("3D").newTexture("Box",#fromImageObject,tBlurryImg)

member("3D").model("Box").shader.texture = tTexture

end if

The following example pushes a Lingo image into a Flash sprite, converts the image to an

ActionScript BitmapData object, and renders the image in Flash:

-- Get a Lingo image

tImage = member("Some Image").image.duplicate()

-- Convert the image object to a BitmapData object

-- inside the Flash sprite that will render the image

tBitmapData = sprite("SWF").convert(#bitmapdata, tImage)

-- Attach the BitmapData object to a movie clip.

-- (Note: this example assumes that on the Stage in the SWF

-- is a movie clip instance named "MovieClip".)

-- (Note: there are additional optional parameters that

-- can be specified in the call to attachBitmap().)

sprite("SWF").MovieClip.attachBitmap(tBitmapData,1)
