CGImageSourceMBS.kCGImageSourceCreateThumbnailFromImageAlways as string

Specifies whether a thumbnail should be created from the full image even if a thumbnail is present in the image source file. The thumbnail will be created from the full image, subject to the limit specified by kCGImageSourceThumbnailMaxPixelSize --- if a maximum pixel size isn't specified, then the thumbnail will be the size of the full image, which probably isn't what you want. The value of this key must be a Boolean; the default value of this key is False.

CGImageSourceMBS.kCGImageSourceCreateThumbnailFromImageIfAbsent as string

Specifies whether a thumbnail should be automatically created for an image if a thumbnail isn't present in the image source file. The thumbnail will be created from the full image, subject to the limit specified by kCGImageSourceThumbnailMaxPixelSize---if a maximum pixel size isn't specified, then the thumbnail will be the size of the full image, which probably isn't what you want. The value of this key must be a Boolean; the default value of this key is False.

Some examples using this method:

• /MacCG/CGImageSource/CGImageSource Thumbnails Threaded
• /MacOSX/Image Thumbnail
