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

CGImageSourceMBS.kCGImageSourceCreateThumbnailWithTransform as string

Specifies whether the thumbnail should be rotated and scaled according to the orientation and pixel aspect ratio of the full image. The value of this key must be a Boolean; the default value of this key is False.

CGImageSourceMBS.kCGImageSourceShouldAllowFloat as string

Specifies whether the image should be returned as a floating point CGImage if supported by the file format. Extended range floating point CGImage may require additional processing to render pleasingly. The value of this key must be a Boolean; the default value is False.
