Function: A class to write CGImages.
Example:

dim logo as Picture = LogoMBS(500)
dim image as CGImageMBS = CGCreateImageMBS(logo)

dim dic as new Dictionary

// 10%
'dic.Value(CGImageDestinationMBS.kCGImageDestinationLossyCompressionQuality)=0.1

// 100%
dic.Value(CGImageDestinationMBS.kCGImageDestinationLossyCompressionQuality)=1.0

dim file as FolderItem = SpecialFolder.Desktop.Child("logo.jpg")
dim d as new CGImageDestinationMBS(file, "public.jpeg", 1)

d.AddImage(image, dic)

if d.Finalize then
  MsgBox "Saved"
else
  MsgBox "Failed to save."
end if

Notes:
CGImageDestination objects, available in Mac OS X v10.4 or later, abstract the data-writing task. An image destination can represent a single image or multiple images. It can contain thumbnail images as well as properties for each image.

The functions described in this reference can write data to three kinds of destinations: a file, an URL and a string. After creating a CGImageDestination object for the appropriate destination, you can add image data and set image properties. When you are finished adding data, call the function Finalize to write the image data and properties.
